技术领域
本发明涉及一种电子技术领域，尤其涉及一种呼叫方法及系统、固定电话机。
背景技术
在现有的固定电话通话系统下，用户可以在运营商处提出注册申请，运营商审核通过以后会分配一个网络端口和一个对应的电话号码给该用户并进行登记。之后，该用户就可以使用连接在这个网络端口的固定电话机拨打或接听电话。其他人就通过拨打给该用户分配的电话号码来联系他。
作为被叫，由于固定电话机的物理端口是固定的，如果用户不在这个电话机位置上(例如换了办公位置，或者下班回家等情况)，而其他人拨打这个电话号码将不能再找到他。或者，如果该用户变更地址后又需要重新申请号码，又要将新号码通知其他人，其他人欲通过固话找到该用户，也往往需要记录下多个固定电话号码(新的办公电话，家庭座机等号码)，非常不方便。
此外，当某一个物理端口和电话号码被分配给某个用户后，这个电话号码对应的电话端口只能被此用户所用。也就是说，别人只能用这个电话号码拨出电话，但是该端口接听的只能是该用户的被叫电话，从一定程度上，必须为每个用户均分配端口和对应的电话号码也是一种资源浪费。

根据本发明实施例，提供了一种呼叫系统。
图1为根据本发明实施例的呼叫系统的结构示意图，如图1所示，根据本发明实施例的呼叫系统包括：电子签名设备10、固定电话机20和服务器30。
电子签名设备10用于存储用户的ID。在具体应用中，用户利用其使用的电子签名设备10在服务器30进行注册，服务器30为该用户分配一个唯一标识(在本发明实施例中称之为用户的ID)，该唯一标识存储在电子签名设备10中。
固定电话机20，用于从电子签名设备10获取用户的ID，以及向服务器30发送签到请求，其中，该签到请求中携带有用户的ID。在具体应用中，当用户需要使用某个固定电话机时，使用其电子签名设备10与固定电话机20进行连接(可以是有线连接，也可以是无线连接)，固定电话机20从电子签名设备10获取用户的ID，然后向服务器30发送携带有该用户的ID的签到请求，指示服务器30该用户的ID对应的用户当前正在使用该固定电话机。其中，固定电话机20从电子签名设备100中获取用户的ID可以是电子签名设备10在与固定电话机20建立连接之后，电子签名设备10主动发送给固定电话机20，从而可以触发固定电话机向服务器30发送签到请求，或者，也可以是电子签名设备10与固定电话机20建立连接之后，固定电话机20向电子签名设备10请求的。例如，可以是固定电话机20在接收到外部输出的指令时，从电子签名设备10获取。其中，该指令可以是指示固定电话机20发送签到请求的，也可以是指示固定电话机20向电子签名设备10请求用户的ID的，具体本实施例不作限定。
服务器30，用于接收上述签到请求，将该用户的ID与发送该签到请求的固定电话机20的通信标识关联存储，以及接收对该用户的ID的呼叫，根据该用户的ID与固定电话机20的通信标识的关联关系，将呼叫接续到与该通信标识对应的固定电话机20。
在本发明实施例提供的技术方案中，将服务器30为用户分配的唯一标识(即用户的ID)存储在电子签名设备10中，通过该唯一标识，全网可以唯一的标识一个用户，该用户在任何一个固定电话机上使用该电子签名设备中存储的该用户的ID进行签到之后，服务器30都可以根据用户的ID，将呼叫该ID的通话接续到该用户当前使用的固定电话机(即固定电话机20)上，从而可以使得用户只需要携带存储ID的电子签名设备，便可以通过同一ID使用不同的固定电话机拨打或接听电话，相对于现有技术中用户的电话号码只能固定在 一个固定电话机上的缺陷，实现了电话号码可以灵活关联到任意一个固定电话机，即实现了电话号码的灵活移动。而且，不同的用户也可以通过同一固定电话机接听电话，提高了设备的利用率。
在本发明实施例提供的技术方案中，固定电话机20为支持电子签名设备的固定电话机。
在本发明实施例中，签到是指用户使用固定电话机20，将电子签名设备20中存储的用户的ID发送给服务器30，服务器30接收到该用户的ID后，将该用户的ID与固定电话机20的通信标识进行关联，从而使服务器30获知该用户当前使用的固定电话机。在该用户在固定电话机20完成在服务器30的签到之后，服务器30接收到对该用户的ID的呼叫，查找到与该用户的ID关联的通信标识，将呼叫接续到与该通信标识对应的固定电话机(即固定电话机20)。
采用本发明实施例提供的技术方案，用户的ID并不会固定的与一个固定电话机进行绑定，通过电子签名设备10，可以方便的将用户的ID与不同固定电话机进行关联，从而使得即使使用固定电话，用户也可以通过同一ID使用不同的固定电话机接听电话，实现了固定电话的移动性。另外，采用本发明实施例提供的技术方案，用户可以通过同一ID方便的使用任意固定电话机接听电话，不同的用户也可以通过同一固定电话机接听电话，提高了设备的利用率。
在本发明实施例的一个可选实施方案中，对于固定电话，固定电话机的通信标识可以是网络为该固定电话机分配的网络端口，在具体实施过程中，通信标识也可以为固定电话机的其它的标识，只要网络侧通过该标识可以与该固定电话机建立连接即可，具体本发明实施例不作限定。
在本发明实施例提供的呼叫系统中，各个用户(1,2,3,……,n-1,n)可以分别使用一个电子签名设备在一个固定电话机上向服务器30进行签到，如图2所示，服务器30将各个用户的ID与其当前使用的固定电话机的通信标识进行关联，在接收到针对某个用户的ID的呼叫时，服务器30根据保存的用户的ID与通信标识的关联关系，获取与呼叫的用户的ID关联的通信标识，将呼叫接续到与该通信标识对应的固定电话机，从而实现呼叫。
在本发明实施例的可选实施方案中，为了提高安全，电子签名设备10可以采用具有安全芯片的装置，其中，安全芯片为具有密码计算的芯片。在具体实施过程中，电子签名设备10可以采用具有安全芯片的智能卡，通过无线的方式(例如NFC、蓝牙等方式)与固定电话机连接，也可以采用具有安全芯片的电子签名钥匙(即KEY，例如：工行使用的U盾、农行使用的K宝等)通过USB接口或音频口与固定电话机30连接，具体形式本发明实施例不作限定。
在本发明实施例的一个可选实施方案中，用户在服务器30进行签到之后，还可以从服务器30释放签到，即解除服务器30中存储的用户的ID与固定电话机的通信标识的关联关系。因此，在该可选实施方式中，服务器30还用于在将所述用户的ID与所述固定电话机的通信标识关联存储之后，删除所述用户的ID与所述固定电话机的通信标识的关联关系。
在具体实施过程中，签到的释放可以是服务器30发起，也可以是固定电话机发起。例如，服务器30可以在预定一段时间内没有接收到某个用户作为被叫或主叫的通话之后，释放该用户的签到；或者，如果服务器30可以即时的获取到用户的位置，则服务器30可以在检测到用户(例如，可以是用户携带的电子签名设备)已远离其关联的固定电话机时，释放该用户的ID与该固定电话机的通信标识的关联关系，在释放该用户的ID与该固定电话机的通信标识的关联关系之后，服务器30可以通知固定电话机20，使得固定电话机20可以获知该信息，在后续如果该用户还需要使用该固定电话机，则需要再次发起签到，即在本发明实施例的一个可选实施方案中，服务器30还用于在删除用户的ID与固定电话机20的通信标识的关联关系之后，通知固定电话机20，服务器30已释放用户的ID的签到。
或者，用户也可以通过固定电话机向服务器30发送释放请求，请求服务器30释放该用户的ID与该固定电话机的通信标识的关联关系，例如，用户可以通过固定电话机拨打一个预定的附加码，向服务器30发送释放请求，或者，用户也可以通过固定电话机的特殊键(例如，删除键)向服务器30发送释放请求，或者，用户也可以通过电子签名设备10触发固定电话机20向服务器30发送释放请求(例如，可以设置长按电子签名设备上的某个功能键即发送释放指令)，释放请求中可以携带请求释放的用户的ID。即在本发明实施例的一个可选实施方案中，固定电话机20还用于在向服务器30发送签到请求之后，向服务器30发送第一释放签到请求，其中，第一释放签到请求中携带有用户的ID；服务器还用于接收第一释放签到请求，触发删除用户的ID与固定电话机20的通信标识的关联关系的操作。
例如，主叫用户在与被叫用户结束通话之后，主叫用户短时间内不会再使用该主叫固定电话机，则主叫用户可以主动通过主叫固定电话机向服务器30发送释放请求，请求服务器30释放主叫用户的ID与主叫固定电话机的通信标识的关联关系，同样，被叫用户也可以在通过被叫固定电话机向服务器30发送请求释放被叫用户的ID与被叫固定电话机的通信标识的关联关系。通过该可选实施例，用户可以在不使用某个固定电话机时，释放与该固定电话机的关联关系，从而使得其它用户可以使用该固定电话机，提高了固定电话机的利用率。
在本发明实施例的一个可选实施方式中，如果某个用户不再使用其注册的ID，则可以向服务器30发送注销请求，注销请求中可以携带请求注销的ID，服务器10在接收到该注 销请求后，可以注销该ID，或者，服务器30也可以在管理员的请求下注销某个ID，即将该ID作废，还可以将该ID重新分配给其它用户。例如，对于某局域网络，如果其中的一用户离开该局域网络，则可以注销该用户的ID。通过该可选实施方式，可以有效的管理为用户分配的ID。
在本发明实施例的一个可选实施方案中，各个电子签名设备中可以保存用户的私钥，而服务器30中可以将用户的ID与其公钥对应保存。为了确保用户身份，在交互过程中，可以对用户的身份进行认证，在认证通过之后，再执行对应的操作。即在交互过程中，电子签名设备10使用其私钥对待签名数据进行签名，然后固定电话机20将签名数据发送至服务器30，通过该签名数据可以对用户的身份进行认证。例如，电子签名设备10中可以存储用户的私钥，而服务器30中可以存储该用户的公钥以及对应的用户的ID。用户在服务器30进行签到时，可以进行签名，即在本发明实施例的一个可选实施方式中，服务器30还用于在将用户的ID与固定电话机20的通信标识关联存储之前，对所述电子签名设备进行身份认证，认证通过后，触发将所述用户的ID与所述固定电话机的通信标识关联存储的操作。具体的可以对签到数据(例如，用户的ID)进行签名，也可以对其它待签名数据(例如，电子签名设备10生成的随机数，或者，服务器30发送的待签名数据，譬如，服务器30生成的随机数或被叫用户的ID)进行签名，具体本发明实施例不作限定，服务器30在接收到签名数据后，利用用户的公钥，对签名数据进行验证，验证通过后，再将用户的ID与固定电话机20的通信标识进行关联。即在本发明实施例的一个可选实施方案中，服务器30通过以下方式对电子签名设备10进行身份认证包括：向固定电话机20发送第一验签请求，以及接收固定电话机20返回的第一验签响应，对第一验签响应中携带的第一签名数据进行验签，其中，在第一验签请求中携带第一待签名数据的情况下，第一验签响应中携带的信息包括：签名得到的第一签名数据；在第一验签请求中没有携带的第一待签名数据的情况下，第一验签响应中的携带的信息包括：第一待签名数据和签名得到的第一签名数据；固定电话机20还用于接收第一验签请求，并将第一验签请求发送给电子签名设备10，以及接收电子签名设备10返回的第一验签响应，并将第一验签响应发送给服务器30；电子签名设备10还用于接收第一验签请求，对第一待签名数据进行签名，以及第一验签响应发送给固定电话机20。
在本发明实施例的一个可选实施方案中，电子签名设备10还用于对第二待签名数据进行签名，将所述第二待签名数据及签名得到的第二签名数据发送给固定电话机20；固定电话机20还用于在向服务器30发送签到请求之前，接收电子签名设备10发送的第二待签名数据及签名得到的第二签名数据；固定电话机20发送给服务器30的签到请求中携带的信息包括：用户的ID、第二待签名数据和第二签名数据；或者，签到请求中携带的信息包括： 第二待签名数据和第二签名数据，其中，第二待签名数据包括用户的ID；服务器30通过以下方式对电子签名设备10进行身份认证：至少根据第二待签名数据对第二签名数据进行验签。
在本发明实施例的一个可选实施方案中，固定电话机20也可以对电子签名设备10进行身份认证，在认证通过的情况下，才向服务器30发送签到请求。即在该可选实施方式中，固定电话机20还用于在向服务器30发送签到请求之前，对电子签名设备10进行身份认证。具体的认证方式与上述服务器30对电子签名设备10的认证相应，即可以是电子签名设备10主动对待签名数据进行签名，将待签名数据及签名得到的签名数据发送给固定电话机20，固定电话机20根据接收到的数据进行验签。或者，也可以是固定电话机20在检测到有电子签名设备10接入时，向接入的电子签名设备10发送验签请求，电子签名设备10接收到该验签请求后，对待签名数据进行签名，然后向固定电话机20返回验签响应，固定电话机20对验签响应中携带的签名数据进行验签。
另外，在本发明实施例的一个可选实施方案中，服务器30还可以在接收到用户的ID的呼叫请求后，也对被叫用户进行身份验证，即在本发明实施例的一个可选实施方案中，服务器30还用于在接收对用户的ID的呼叫后，向固定电话机20发送携带有第五待签名数据的第三验签请求，以及接收固定电话机20返回的第五签名数据，对第五签名数据进行验签，在验签通过之后，触发将呼叫接续到固定电话机20的操作；固定电话机20还用于接收第三验签请求，并将第三验签请求发送给电子签名设备10，以及接收电子签名设备10返回的第五签名数据，并将第五签名数据发送给服务器30；电子签名设备10还用于接收第三验签请求，对第五待签名数据进行签名，以及将签名得到的第五签名数据发送给固定电话机20。
在固定电话机20发起释放请求时，固定电话机20也可以从电子签名设备10获取身份认证数据，在释放请求中携带身份认证数据(或者，也可以在发起释放请求之后，由服务器30向固定电话机20发送认证请求，固定电话机20响应服务器30的请求，由电子签名设备10对待签名数据进行签名得到身份认证数据，然后发送给服务器30)。
即，在本发明实施例的一个可选实施方案中，固定电话机20还用于向服务器30发送释放签到请求之前，接收电子签名设备10发送的第二释放签到请求，其中，第二释放签到请求中携带有第三待签名数据以及对第三待签名数据进行签名得到的第三签名数据；第一释放签到请求中还携带有第三待签名数据以及第三签名数据；服务器30按照以下方式删除用户的ID与固定电话机的通信标识的关联关系：根据第三待签名数据对第三签名数据进行验签，验签通过之后，删除用户的ID与固定电话机的通信标识的关联关系。
在本发明实施例的另一个可选实施方案中，服务器30还用于向固定电话机20发送携 带第四待签名数据的第二验签请求，以及接收固定电话机返回的第四签名数据，并对第四签名数据进行验签，在验签通过之后，触发删除用户的ID与固定电话机的通信标识关联关系的操作；固定电话机20还用于接收第二验签请求，并将第二验签请求发送给电子签名设备10，以及接收电子签名设备10返回的第四签名数据，并将第四签名数据返回给服务器30；电子签名设备10还用于接收第二验签请求，对第四待签名数据进行签名，以及将签名得到的第四签名数据发送给固定电话机20。
虽然上面只列举了上述三种情况需要进行身份认证为例进行说明，但并不限于此，在实际应用中，对于其它可能的流程，服务器30也可以先对用户进行身份认证，认证通过后再执行后续的流程。
通过对电子签名设备10进行身份认证，避免了通话某一方恶意模仿进行诈骗的情况，提高了呼叫系统的安全性。
在本发明实施例的一个可选实施方案中，为了兼容现在的电话呼叫系统，服务器30用于接收对用户的ID的呼叫之后，判断该呼叫的类型为预设的呼叫类型，触发将呼叫接续到固定电话机20的操作。即在该可选实施方式中，服务器30可以实现两种呼叫方式，一种是现有的呼叫方式，即呼叫每个固定电话机使用的电话号码的方式，另一种则是呼叫用户的ID的方式，服务器30在接收到一个呼叫之后，先判断该呼叫的类型，在该呼叫的类型为呼叫用户的ID的类型时，则按照存储的用户的ID与固定电话机的通信标识的关联关系进行呼叫接续，否则，按照现有的呼叫方式进行。
作为本发明实施例的一个可选实施方案，固定电话机20可以与电子签名设备10间通过无线方式连接，也可以通过有线方式连接，无线方式可以包括但不限于：蓝牙、WIFI、NFC、红外或RFID等方式；有线方式可以包括但不限于：USB、音频(耳机插头)RJ11、RJ45或串口等方式。
实施例2

下面将结合附图对本发明实施例的呼叫方法作进一步地描述。
如图3所示，本实施例提供的呼叫方法主要可以包括以下步骤(S302至S308)。
步骤S302，固定电话机从电子签名设备获取用户的ID。
其中，用户的ID为用户在服务器上为用户使用的电子签名设备注册的唯一标识；在注册时，电子签名设备保存用户的ID，用户的ID可以是但不限于以下方式：数字、字母、字符、汉字之一或其组合。该ID相当于现有通信系统中用户的电话号码，方便主叫固定电话机呼叫被叫用户。
其中，电子签名设备包括但不限于具有安全芯片的电子签名钥匙(KEY设备，例如工行的U盾或农行的K宝等)、具有安全芯片的智能卡等，其中，安全芯片能够进行签名运算、加解密运算、协商传输密钥的功能。

A10、固定电话机从电子签名设备的数字证书中获取电子签名设备的公钥，利用电子签名设备的公钥对接收的签名值S2进行验签，如果验签通过，则执行后续操作，如果验签不通过，则停止身份认证流程，也可以向电子签名设备反馈验签不通过的消息。
(2)方式二：
B1、固定电话机(固定电话机可以为被叫固定电话机或者主叫固定电话机)生成随机数R1，并将随机数R1发送至电子签名设备；
B2、电子签名设备(可以为第一电子签名设备或者第二电子签名设备)接收到随机数R1后，生成随机数R2，将随机数R2和电子签名设备的数字证书发送至固定电话机；
B3、固定电话机利用预存的根证书校验接收的电子签名设备的数字证书的合法性，如果校验该固定电话机的数字证书合法，则执行B4，如果校验该固定电话机的数字证书不合法，则停止身份认证流程，必要时，可以向电子签名设备反馈校验证书不通过的消息；

B5、固定电话机将签名值S1以及固定电话机的数字证书发送至电子签名设备；
B6、电子签名设备利用预存的根证书校验接收的固定电话机的数字证书的合法性，如果校验该固定电话机的数字证书合法，则执行B7，如果校验该固定电话机的数字证书不合法，则停止身份认证流程，必要时，可以向固定电话机反馈校验证书不通过的消息；
B7、电子签名设备从固定电话机的数字证书中获取固定电话机的公钥，利用固定电话机的公钥对接收的签名值S1进行验签，如果验签通过，则执行后续操作，如果验签不通过，则停止身份认证流程，也可以向固定电话机反馈验签不通过的消息。
当然，除了上述两种方式外，固定电话机对电子签名设备进行身份认证还有其他方式，本领域技术人员在本发明基础上扩展的其他身份认证方式都应该是本发明的保护范围。
步骤S304，固定电话机向服务器发送签到请求，其中，签到请求中携带有用户的ID。
在具体应用中，固定电话机可以是在电子签名设备一接入到固定电话机后，即执行步 骤S302，然后执行步骤S304，也可以是在电子签名设备接入到固定电话机后，接收到发送签到请求的指示指令时，执行步骤S304。
步骤S306，服务器接收签到请求，将用户的ID与固定电话机的通信标识关联存储。
在本发明实施例的一个可选实施方案中，用户使用电子签名设备向服务器提出注册申请，服务器可以向电子签名设备办法证书或者使用电子签名设备内已有的其他认证单位办法的证书，服务器为用户分配一个唯一标识作为用户的ID，并将用户的ID与颁发给电子签名设备的证书绑定存储，由此，服务器可以通过为电子签名设备颁发的证书来验证电子签名设备的身份。具体的，可以通过但不限于如下方式之一进行注册：
方式一：用户持电子签名设备向服务器发送账号申请，服务器审核用户身份通过后，向电子签名设备发送密钥生成指令，电子签名设备生成密钥对，并将公钥发送至服务器，服务器生成电子签名设备的公钥证书，分配唯一标识作为用户的ID，将用户的ID与公钥证书绑定存储，并为电子签名设备签发证书，并将签发的证书发送至电子签名设备，电子签名设备保存服务器签发的证书。通过此种方式，由电子签名设备生成密钥对，保证密钥的安全性。
方式二：用户持电子签名设备向服务器发送账号申请，服务器审核用户身份通过后，向电子签名设备发送读取证书指令，电子签名设备将证书发送至服务器，服务器验证证书的合法性，并在证书合法后，分配唯一标识作为用户的ID，将用户的ID与证书绑定存储。通过此种方式，利用电子签名设备已有的证书进行绑定，提高了注册效率。
当然，为了保证用户身份合法，在本发明实施例的一个可选实施方案中，在本步骤中，固定电话机在发送签到请求时，除了携带用户的ID外，还可以在签到请求中携带身份认证数据并发送至服务器，以便服务器对用户的身份进行认证，保证身份合法。即在步骤S304之前，电子签名设备对待签名数据进行签名，得到身份认证数据，将身份认证数据发送给固定电话机，固定电话机将身份认证数据携带在签到请求中发送给服务器；该身份认证数据可以通过如下方式之一得到：
方式一：电子签名设备对用户的ID进行签名获得的签名数据。
方式二：电子签名设备待签名数据进行签名获得的签名数据，该待签名数据可以包括单次认证数据，该单次认证数据可以为电子签名设备生成的(在这种情况下，签到请求中还携带有该单次认证数据)，也可以为固定电话机接收到服务器发送的并发送至电子签名设备的。该单次认证数据可以为随机数和事件因子之一或其组合，其中事件因子可以为每生成一次累计+1或任意值等方式生成的。
方式三：电子签名设备对待签名数据和用户的ID进行签名获得的签名数据，其中，该待签名数据可以包括单次认证数据，该单次认证数据可以为电子签名设备生成的(在这种 情况下，签到请求中还携带有该单次认证数据)，也可以为固定电话机接收到服务器发送的并发送至电子签名设备的。该单次认证数据可以为随机数和事件因子之一或其组合，其中事件因子可以为每生成一次累计+1或任意值等方式生成的。
方式四：电子签名设备在注册时设置的密码或者与电子签名设备关联的动态口令牌生成的动态密码。
如果固定电话机在发送的签到请求中携带了身份认证数据，在服务器收到固定电话机的签到请求之后，本步骤中，服务器还可以对接收到的被叫固定电话机发送的身份认证数据进行认证，并在认证通过后，执行将用户的ID与被叫固定电话机的通信标识进行关联并存储的步骤。具体的，服务器可以通过用户在服务器上为电子签名设备注册时存储的电子签名设备的公钥对签名数据进行验签的方式进行身份认证，也可以验证静态密码或者动态密码的方式进行身份认证。由此保证只有在认证用户身份合法后，才执行将用户的ID与固定电话机的通信标识进行关联并存储的步骤，保证用户签到的合法性。
在本发明实施例的一个可选实施方案中，如果签到请求中没有携带身份认证数据，则服务器在接收到签到请求后，向固定电话机发送第一验签请求；固定电话机接收第一验签请求，并将第一验签请求发送给电子签名设备；电子签名设备接收到第一验签请求，对第一待签名数据进行签名，向固定电话机发送第一验签响应，其中，在第一验签请求中携带第一待签名数据的情况下，第一验签响应中携带的信息包括：签名得到的第一签名数据；在第一验签请求中没有携带的第一待签名数据的情况下，第一验签响应中的携带的信息包括：第一待签名数据和签名得到的第一签名数据；固定电话机将接收到的第一验签响应发送给服务器；服务器接收到第一验签响应，对第一验签响应中携带的第一签名数据进行验签。
步骤S308，服务器接收对用户的ID的呼叫，根据用户的ID与固定电话机的通信标识的关联关系，将呼叫接续到与通信标识对应的固定电话机。
可选地，在步骤S308中，在服务器接收对用户的ID的呼叫后，服务器还可以对呼叫的用户的ID进行认证，从而可以验证被呼叫的用户是否在线。即服务器向与呼叫的用户的ID关联的通信标识对应的固定电话机发送第三验签请求，其中，第三验签请求中携带有第五待签名数据；固定电话机接收第三验签请求，并将第三验签请求发送给电子签名设备；电子签名设备接收第三验签请求，对第五待签名数据进行签名；电子签名设备将签名得到的第五签名数据发送给固定电话机；固定电话机将接收到的第五签名数据发送给服务器；服务器接收到第五签名数据，对第五签名数据进行验签，在验签通过之后，执行将呼叫接续到固定电话机的步骤。
在本发明实施例的一个可选实施方案中，为了兼容现在的电话呼叫系统，服务器接收 对用户的ID的呼叫之后，判断该呼叫的类型为预设的呼叫类型，执行将呼叫接续到固定电话机的步骤。即在该可选实施方式中，服务器可以实现两种呼叫方式，一种是现有的呼叫方式，即呼叫每个固定电话机使用的电话号码的方式，另一种则是呼叫用户的ID的方式，服务器在接收到一个呼叫之后，先判断该呼叫的类型，在该呼叫的类型为呼叫用户的ID的类型时，则按照存储的用户的ID与固定电话机的通信标识的关联关系进行呼叫接续，否则，按照现有的呼叫方式进行。判断所述呼叫的类型为预设的呼叫类型，执行将所述呼叫接续到所述固定电话机的步骤。
在本发明实施例的一个可选实施方案中，服务器在将用户的ID与固定电话机的通信标识关联存储之后，还可以删除该用户的ID与固定电话机的通信标识的关联关系。基于此，服务器可以释放对用户的签到，不影响被用户签到的固定电话机的正常使用。当然，服务器可以通过如下方式至少之一触发释放对被叫用户的签到的流程：接收被叫固定电话机发送的释放签到指令后、服务器判断需要释放签到后。
即在本发明实施例的一个可选实施方案中，在固定电话机向服务器发送签到请求之后，服务器删除用户的ID与固定电话机的通信标识的关联关系之前，固定电话机向服务器发送第一释放签到请求，其中，第一释放签到请求中携带有所述用户的ID；服务器接收所述第一释放签到请求。
在本发明实施例的一个可选实施方案中，如果服务器接收到固定电话机发送的释放签到指令，则服务器还可以对用户的身份进行验证，以保证释放签到的用户身份合法。因此，在该可选实施方式中，固定电话机向服务器发送释放签到请求之前，固定电话机接收电子签名设备发送的第二释放签到请求(可以是电子签名设备主动向固定电话机发送的，也可以是固定电话机向电子签名设备请求的)，其中，第二释放签到请求中携带有第三待签名数据以及对第三待签名数据进行签名得到的第三签名数据；则固定电话机向服务器发送的第一释放签到请求中还携带有第三待签名数据以及第三签名数据；服务器删除用户的ID与所述固定电话机的通信标识的关联关系可以包括：服务器至少根据第三待签名数据对所述第三签名数据进行验签，验签通过之后，删除用户的ID与固定电话机的通信标识的关联关系。
或者，在本发明实施例的一个可选实施方案中，服务器删除用户的ID与固定电话机的通信标识的关联关系之前，服务器可以向固定电话机发送第二验签请求，其中，第二验签请求中携带有第四待签名数据；固定电话机接收第二验签请求，并将第二验签请求发送给电子签名设备；电子签名设备接收到第二验签请求，对第四待签名数据进行签名；电子签名设备将签名得到的第四签名数据发送给固定电话机；固定电话机将接收到的第四签名数据发送给服务器；服务器接收到第四签名数据，对第四签名数据进行验签，在验签通过之后，执行删除用户的ID与固定电话机的通信标识关联关系的步骤。
在本发明实施例的一个可选实施方案中，如果是服务器判断需要释放签到，则在删除用户的ID与固定电话机的通信标识关联关系之后，服务器还可以通知固定电话机，服务器已释放用户的ID的签到。从而使得固定电话机可以获取当前服务器已释放该用户的ID的签到。
在本发明实施例中，在固定电话机与电子签名设备完成了身份认证之后，固定电话机与电子签名设备之间还可以协商出一个传输密钥，并将该传输密钥发送至服务器，服务器保存该传输密钥，用于后续固定电话机、服务器以及电子签名设备之间数据传输的加/解密。
由此可见，通过本发明实施例的呼叫方法，由于固定电话机向服务器发送了签到请求，告知服务器用户使用的是哪一个固定电话机，服务器由此可以将该固定电话机与用户进行关联，由此可以在接收到主叫固定电话机对该用户的呼叫时，将主叫固定电话机的呼叫接入该用户签到的固定电话机上，由此可以保证被叫用户无论使用哪一个固定电话机，只要在该固定电话机处进行了签到，就可以找到该被叫用户，方便了使用。
实施例3
本实施例提供了一种固定电话机。

在本发明实施例提供的技术方案中，采用本发明实施例提供的技术方案，用户的ID并不会固定的与一个固定电话机进行绑定，通过电子签名设备10，可以方便的将用户的ID与不同固定电话机进行关联，从而使得即使使用固定电话，用户也可以通过同一ID使用不同的固定电话机接听电话，实现了固定电话的移动性。另外，采用本发明实施例提供的技术方案，用户可以通过同一ID方便的使用任意固定电话机接听电话，不同的用户也可以通过同一固定电话机接听电话，提高了设备的利用率。
可选地，第一收发模块404还可以用于接收服务器发送的第一验签请求；第二收发模块还402用于将第一验签请求发送给电子签名设备，以及接收电子签名设备返回的第一验签响应，其中，在第一验签请求中携带第一待签名数据的情况下，第一验签响应中携带的信息包括：签名得到的第一签名数据，在第一验签请求中没有携带的第一待签名数据的情况下，第一验签响应中的携带的信息包括：第一待签名数据和签名得到的第一签名数据；第一收发模块404还用于将接收到的第一验签响应发送给服务器。
可选地，第二收发模块402还用于接收电子签名设备发送的第二待签名数据及电子签 名设备对第二待签名数据进行签名得到的第二签名数据；第一收发模块404发送的签到请求中携带的信息包括：用户的ID、第二待签名数据和第二签名数据；或者，签到请求中携带的信息包括：第二待签名数据和第二签名数据，其中，第二待签名数据包括用户的ID。
可选地，还可以包括：认证模块，用于对电子签名设备进行身份认证。在认证通过的情况下，第一收发模块才向服务器发送签到请求。具体的认证方式可以参见上述实施例1和实施例2中的描述，在此不再赘述。
可选地，第一收发模块404还可以用于向服务器发送第一释放签到请求，其中，第一释放签到请求中携带有用户的ID。即固定电话机可以主动发送释放签到请求，从而可以在用户不再使用时某个固定电话机时，通知服务器，使得其它用户可以使用该固定电话机，从而提高固定电话机的使用率。
可选地，第二收发模块402还可以用于接收电子签名设备发送的第二释放签到请求，其中，第二释放签到请求中携带有第三待签名数据以及对第三待签名数据进行签名得到的第三签名数据；第一收发模块404发送的第一释放签到请求中还可以携带有第三待签名数据以及第三签名数据。在该可选实施方式中，固定电话机在发起释放时，同时将身份认证数据发送给服务器，从而使得服务器可以同时进行认证，提高了安全性，并且节约了流程。
可选地，第一收发模块404还可以用于接收服务器发送的携带第四待签名数据的第二验签请求；第二收发模块402还可以用于将第二验签请求发送给电子签名设备，以及接收电子签名设备返回对第四待签名数据进行签名得到的第四签名数据；第一收发模块402还可以用于将第四签名数据返回给服务器。在该可选实施方式中，在服务器发起验签要求的情况下，固定电话机通知电子签名设备进行签名。
可选地，第一收发模块404还可以用于接收服务器发送的通知，其中，通知指示服务器已释放用户的ID的签到。在该可选实施方案中，在服务器主动释放签到的情况下，固定电话机可以及时获知，避免由于用户不知道服务器以释放签到的情况下，而漏掉重要电话的情况。
可选地，第一收发模块404还可以用于在通话模块接收服务器发送的呼叫之前，接收服务器发送的携带有第五待签名数据的第三验签请求；第二收发模块402还可以用于将第三验签请求发送给电子签名设备，以及接收电子签名设备返回对第五待签名数据进行签名得到的第五签名数据；第一收发模块404还可以用于将第五签名数据发送给服务器。从而使得服务器可以在将呼叫接续到固定电话机之前，确定用户是否在线。
从上述实施例可以看出，相对于现有技术，上述实施例中提供的呼叫方法及系统，可以将用户的ID与不同固定电话机关联，从而使得用户只需要携带存储ID的电子签名设备，便可以通过同一ID使用不同的固定电话机拨打或接听电话，相对于现有技术中用户的电话 号码只能固定在一个固定电话机上的缺陷，实现了电话号码可以灵活关联到任意一个固定电话机，即实现了电话号码的灵活移动。而且，不同的用户也可以通过同一固定电话机接听电话，提高了设备的利用率。固定电话机可以利用其电子签名设备进行身份认证以及协商传输密钥，通过对主叫用户或被叫用户进行身份认证，避免了通话某一方恶意模仿进行诈骗的情况，提高了通话系统的安全性。在通话过程中，使用传输密钥对传输数据进行加解密，保证通话数据的安全。

通过本可选实施方案，能够利用智能密码设备对通话一方或双方或多方通信人身份进行认证，确保通话一方或双方或多方的身份合法，保证通话的安全。
在本实施例的一个可选实施方式中，通话过程中，可以通过电子签名设备200对终端100发送的通话数据进行加密，对终端100接收到的通话数据进行解密。因此，在该可选实施方式中，第二通话数据可以为经由电子签名设备200对第一通话数据进行解密得到的；第四通话数据可以为经由电子签名设备200对第三通话数据进行加密得到的。通过该可选实施方式，由通信接口101接收网络上其他终端发来的加密数据，将收到的加密数据经由电子签名设备200进行解密后传输给听筒104，用户在听筒104听到正确解密的数据(即用户可以正常听到对方的说话)；当用户需要说话时，麦克105接收到用户的语音数据，将该语音数据发送至电子签名设备200，由电子签名设备200加密后再发送至通信接口101进行往外发出，从而保证了收发数据的安全性，防止用户信息的外泄。
在本实施例的可选实施方式中，电子签名设备200中使用的对通话数据进行加解密的 加解密密钥(可以称之为传输密钥)还可以及时地进行更换，提高安全级别，例如，通话双方的电子签名设备200可以按照以下方式更换传输密钥：(1)根据跳变触发因子，将当前的传输密钥跳变为新的传输密钥；(2)获取到密钥跳变指令，将当前的传输密钥跳变为新的传输密钥。其中，跳变触发因子包括但不限于以下至少之一：跳变周期、跳变时间点、和通话数据量。密钥跳变指令包括但不限于以下至少之一：通话对端发送的密钥跳变指令、输入的密钥跳变指令、和根据预设规则生成的密钥跳变指令。通过该可选实施方式，可以为用户提供多种传输密钥更换的实现方案。

实施例5
本实施例提供另一种终端，本实施例的终端与实施例4中的终端的区别在于，本实施例中控制模块是安全芯片，该安全芯片具有密码计算功能，可以完成加/解密操作。以下仅对本实施例中与实施例4中不同之处进行简单说明。
如图8所示，终端300包括：通信接口301，控制模块302以及电子签名设备接口303；其中，电子签名设备接口303，用于从电子签名设备接收签到数据，并将签到数据发送至控制模块302，签到数据至少包括终端的用户的ID；控制模块302，用于将签到数据发送 至通信接口301；通信接口301，用于将签到数据外发。
可选地，该终端300还可以包括：听筒304以及麦克305；通信接口301，还可以用于接收来自外部的第一通话数据，并将第一通话数据发送至控制模块302；控制模块302，还可以用于将第一通话数据对应的第二通话数据发送至听筒304；接收麦克305发送的第三通话数据，将第三通话数据对应的第四通话数据发送至通信接口301；通信接口301，还可以用于将第四通话数据外发。
本实施例中，控制模块302为安全芯片307。该安全芯片可以独立地完成数据的加解密，从而无需将数据传输给电子签名设备进行加解密，节约了传输时间，提高了通话效率。
具体的，第二通话数据为经由安全芯片307对第一通话数据进行解密得到的；第四通话数据为经由安全芯片307对第三通话数据进行加密得到的。由通信接口301接收网络上其他电话发来的加密数据，将收到的加密数据经由安全芯片307进行解密后传输给听筒，用户在听筒听到正确解密的数据(即用户可以正常听到对方的说话)；当用户需要说话时，麦克接收到用户的语音数据，将该语音数据发送至安全芯片307，由安全芯片加密后再发送至通信接口进行往外发出，从而保证了收发数据的安全性，防止用户信息的外泄。
在本实施例的一个可选实施方式中，终端300还可以包括：输入装置306，用于为用户提供输入信息到终端的装置，输入装置可以是键盘等。当用户需要拨打电话时，可以通过输入装置输入被叫用户的ID。
在本实施例的一个可选实施方式中，安全芯片307还可以对输入装置306输入的数据进行加密，在该可选实施方式中，输入装置306，用于接收到输入的第一输入数据，并将第一输入数据发送至安全芯片307；安全芯片307，用于将第一输入数据对应的第二输入数据发送至通信接口301；第二输入数据为经由电子签名设备40对第一输入数据进行加密得到的。从而可以保证用户输入信息的传输安全。
此外，安全芯片307，还用于从电子签名设备接口303接收到传输密钥，并保存传输密钥。安全芯片307使用的传输密钥由电子签名设备200生成，进一步保证数据传输的安全性。
在本实施例的一个可选实施方式中，安全芯片307还可以用于从电子签名设备接口303或者通信接口301或者输入装置接收释放签到数据，将保存的传输密钥删除。当通话结束后，或者用户不在终端身旁，或者按下特殊按钮均可以触发释放签到流程。当触发释放签到流程时，终端上的安全芯片307在接收到释放签到数据时，为了保证密钥的安全，在释放签到时，同时也将保存的传输密钥删除。通过该可选实施方式，可以及时释放终端中存储的传输密钥，避免由于没能及时删除传输密钥而导致别的用户无法使用该终端的问题。
在本实施例的一个可选实施方式中，安全芯片307还可以用于对电子签名设备40进 行认证。安全芯片307可以预先保存被叫用户的公钥，在从电子签名设备40获取被叫用户的ID或签名数据或传输密钥时，可以指示电子签名设备40发送身份认证数据，电子签名设备40接收到指示后，利用保存在私钥对待签名数据进行签名后得到身份认证数据，将身份认证数据发送给安全芯片307，安全芯片307利用公钥对身份认证数据进行认证，并在认证通过后，继续执行后续流程。其中，在该可选实施方式中，待签名数据可以是安全芯片307发送给电子签名设备40的，也可以是电子签名设备40自己确定的，这种情况下，电子签名设备40可以将待签名数据的明文与身份认证数据一起发送给安全芯片307。当然，安全芯片307对电子签名设备40进行身份认证还可以是其他形式的认证，例如通过密码方式进行认证等。通过该可选实施方式，使得终端也能验证电子签名设备的真实身份，防止被假的电子签名设备欺诈，保证用户的安全。
此外，安全芯片307，还可以用于将当前传输密钥条变为新的传输密钥。定期更换新的传输密钥，保证传输安全。
实施例6
根据本发明实施例，提供了一种通话系统。
图9为根据本发明实施例的通话系统的结构示意图，如图9所示，根据本发明实施例的通话系统包括：被叫终端110、主叫终端120、服务器130、以及与被叫终端110连接的第一电子签名设备140。
在本发明实施例提供的技术方案中，被叫终端110为支持电子签名设备的终端，被叫用户利用其使用的第一电子签名设备140在服务器130进行注册，服务器130为被叫用户分配一个唯一标识(在本发明实施例中称之为被叫用户的ID)，该唯一标识存储在第一电子签名设备140中，通过该唯一标识，全网可以唯一的标识被叫用户，被叫用户在任何一个终端上签到之后，服务器都可以根据被叫用户的ID，将呼叫该ID的通话接续到该用户当前使用的终端(即被叫终端110)上。
在本发明实施例中，签到是指用户使用被叫终端110，将第一电子签名设备140中存储的被叫用户的ID发送给服务器130，服务器130接收到该被叫用户的ID后，将该被叫用户的ID与被叫终端130的通信标识进行关联，从而使服务器130获知该被叫用户当前使用的终端。在被叫用户在被叫终端110完成在服务器130的签到之后，服务器130接收到主叫终端120呼叫该被叫用户的ID的呼叫请求后，查找到与该被叫用户的ID关联的通信标识，将呼叫接续到与该通信标识对应的终端(即被叫终端110)。
采用本发明实施例提供的技术方案，被叫用户的ID并不会固定的与一个终端进行绑定，通过第一电子签名设备140，可以方便的将被叫用户的ID与不同终端进行关联，从而 使得即使使用固定电话，用户也可以通过同一ID使用不同的终端接听电话，实现了固定电话的移动性。并且，对于移动终端，用户也不必像现有技术中一般，无论到什么地方都需要携带安装SIM卡的移动终端，只需要携带存储ID的第一电子签名设备140即可。另外，采用本发明实施例提供的技术方案，用户可以通过同一ID方便的使用任意终端(包括固定终端和移动终端，即被叫终端110可以是固定终端也可以是移动终端)接听电话，不同的用户也可以通过同一终端接听电话，提高了设备的利用率。
在本发明实施例的一个可选实施方案中，对于固定电话，终端的通信标识可以是网络为该终端分配的网络端口，对于移动终端，终端的通信标识可以是移动终端的SIM卡的鉴权密钥等，对于终端上的可以进行通话的客户端，该通信标识可以是客户端当前使用的IP地址等，在具体实施过程中，通信标识也可以为终端的其它的标识，只要网络侧通过该标识可以与该终端建立连接即可，具体本发明实施例不作限定。
在本发明实施例的一个可选实施方案中，该系统还可以包括：与主叫终端120连接的第二电子签名设备150。通过该可选实施方案，主叫用户也可以通过主叫终端120向服务器130发起签到，从第二电子签名设备150中读取主叫用户的ID，并将主叫用户的ID发送给服务器130，服务器130将该主叫用户的ID与主叫终端120的通信标识进行关联。采用该可选实施方案，服务器130在接收到主叫终端120的呼叫请求时，可以根据与主叫终端120关联的主叫用户的ID，向被叫提供主叫用户的ID，从而使得被叫用户可以判断主叫用户的身份。即在本发明实施例中，可以采用如图7所示的系统，各个用户(1,2,3,……,n-1,n)分别使用一个电子签名设备在一个终端上向服务器130进行签到，服务器130将各个用户的ID与其当前使用的终端的通信标识进行关联，主叫用户使用被叫用户的ID作为被叫标识通过主叫终端120发起呼叫到服务器130，服务器130接收到呼叫请求后，从呼叫请求中获取到被叫用户的ID,查找与该被叫用户的ID关联的通信标识，然后将呼叫接续到与该通信标识对应的被叫终端110。
在现有技术中，作为主叫，当用户不在其使用的电话机位置上时，比如用其他用户的电话拨打电话时，被叫用户则无法得知该电话是由该用户拨打的，有可能会不接或漏接，错过重要的电话，或给双方造成误解，对用户的工作或生活都会带来不便。通过本发明实施例的上述可选实施方式，即使主叫用户不是在其绑定的电话机拨打电话，但被叫显示的还是该主叫用户的ID，从而解决了被叫用户无法得知拨打该呼叫的主叫用户的身份的问题，从而提高了用户体验。
在本发明实施例的一个可选实施方案中，用户在服务器130进行签到之后，还可以从服务器130释放签到，即解除服务器130中存储的用户的ID与终端的通信标识的关联关系。在具体实施过程中，签到的释放可以是服务器130发起，也可以是终端发起。例如，服务 器130可以在预定一段时间内没有接收到某个用户作为被叫或主叫的通话之后，释放该用户的签到；或者，如果服务器130可以即时的获取到用户的位置，则服务器130可以在检测到用户(例如，可以是用户携带的电子签名设备)已远离其关联的终端时，释放该用户的ID与该终端的通信标识的关联关系。或者，用户也可以通过终端向服务器130发送释放请求，请求服务器130释放该用户的ID与该终端的通信标识的关联关系，例如，用户可以通过终端拨打一个预定的附加码，向服务器130发送释放请求，或者，用户也可以通过终端的特殊键(例如，删除键)向服务器130发送释放请求，或者，用户也可以通过电子签名设备触发终端向服务器130发送释放请求(例如，可以设置长按电子签名设备上的某个功能键即发送释放指令)，释放请求中可以携带请求释放的用户的ID。例如，主叫用户在与被叫用户结束通话之后，主叫用户短时间内不会再使用该主叫终端120，则主叫用户可以主动通过主叫终端120向服务器130发送释放请求，请求服务器130释放主叫用户的ID与主叫终端120的通信标识的关联关系，同样，被叫用户也可以在通过被叫终端110向服务器130发送请求释放被叫用户的ID与被叫终端130的通信标识的关联关系。通过该可选实施例，用户可以在不使用某个终端时，释放与该终端的关联关系，从而使得其它用户可以使用该终端，提高了终端的利用率。
在本发明实施例的一个可选实施方式中，如果某个用户不再使用其注册的ID，则可以向服务器130发送注销请求，注销请求中可以携带请求注销的ID，服务器130在接收到该注销请求后，可以注销该ID，或者，服务器130也可以在管理员的请求下注销某个ID，即将该ID作废，还可以将该ID重新分配给其它用户。例如，对于某局域网络，如果其中的一用户离开该局域网络，则可以注销该用户的ID。通过该可选实施方式，可以有效的管理为用户分配的ID。
在本发明实施例的可选实施方案中，为了提高安全，第一电子签名设备140可以采用具有安全芯片的装置，其中，安全芯片为具有密码计算的芯片。在具体实施过程中，第一电子签名设备140可以采用具有安全芯片的智能卡，通过无线的方式(例如NFC、蓝牙等方式)与终端连接，也可以采用具有安全芯片的电子签名钥匙(即KEY，例如：工行使用的U盾、农行使用的K宝等)通过USB接口或音频口与终端连接，具体形式本发明实施例不作限定。在本发明实施例的一个可选实施方案中，第二电子签名设备150可以采取与第一电子签名设备140相似的方式，具体不再赘述。
在本发明实施例的一个可选实施方案中，各个电子签名设备中可以保存用户的私钥，而服务器130中可以将用户的ID与其公钥对应保存。为了确保用户身份，在交互过程中，可以对用户的身份进行认证，在认证通过之后，再执行对应的操作。即在交互过程中，电子签名设备使用其私钥对待签名数据进行签名，然后终端将签名数据发送至服务器，通过 该签名数据可以对用户的身份进行认证。例如，以被叫侧为例，第一电子签名设备140中可以存储被叫用户的私钥，而服务器130中可以存储被叫用户的公钥以及对应的被叫用户的ID。被叫用户在服务器进行签到时，可以进行签名，具体的可以对签到数据(例如，被叫用户的ID)进行签名，也可以对其它待签名数据(例如，第一电子签名设备140生成的随机数，或者，服务器130发送的待签名数据，譬如，服务器130生成的随机数或被叫用户的ID)进行签名，具体本发明实施例不作限定，服务器130在接收到签名数据后，利用被叫用户的公钥，对签名数据进行验证，验证通过后，再将被叫用户的ID与被叫终端110的通信标识进行关联。另外，在本发明实施例的一个可选实施方案中，服务器130还可以在接收到被叫用户的ID的呼叫请求后，也对被叫用户进行身份验证，即向被叫用户的ID关联的通信标识对应的被叫终端110发送验证请求，请求被叫终端110发送身份认证数据，然后对被叫终端130发送的身份认证数据进行认证，认证通过后再将呼叫接续到被叫终端130。在被叫终端110发起释放请求时，被叫终端110也可以从第一电子签名设备140获取身份认证数据，在释放请求中携带身份认证数据(或者，也可以在发起释放请求之后，由服务器130向被叫终端110发送认证请求，被叫终端110响应服务器130的请求，由第一电子签名设备140对待签名数据进行签名得到身份认证数据，然后发送给服务器130)。
虽然上面只列举了上述三种情况需要进行身份认证为例进行说明，但并不限于此，在实际应用中，对于其它可能的流程，服务器130也可以先对被叫用户进行身份认证，认证通过后再执行后续的流程。
虽然上述只列举了被叫侧的情况，但对于主叫侧来说，也可以执行相应的流程对主叫用户进行认证，例如，主叫终端120在发起呼叫时，可以发送签名数据，服务器130根据该签名数据对主叫用户进行认证，认证通过后再将呼叫接续到被叫终端110。具体不再赘述。
通过对主叫用户或被叫用户进行身份认证，避免了通话某一方恶意模仿进行诈骗的情况，提高了通话系统的安全性。
在本发明实施例的一个可选实施方案中，为了保证通话数据的安全，还可以对通话过程中的传输数据进行加密。在该可选实施方式中，主叫终端120和被叫终端110可以通过各自连接的电子签名设备与对端协商传输密钥，在通话过程中，主叫终端120和被叫终端110通过其连接的电子签名设备对传输数据进行加解密。或者，也可以在主叫终端120和被叫终端110中分别设置一个加解密模块，通过加解密模块分别与对应的电子签名设备协商传输密钥，在通话过程中，通过加解密模块对传输数据进行加解密。通过该可选实施方式，可以确保通话数据的安全。
在本发明实施例的一个可选实施方案中，被叫终端110可以包括实施例2及其中各个 可选的实施方式的结构装置，主叫终端120可以包括实施例8及其中各个可选的实施方式的结构装置，服务器130可以包括实施例9及其中各个可选的实施方式的结构装置，具体描述参见下述各个实施例的描述，在此不再赘述。
实施例7
本实施例提供了一种通话装置，该通话装置可以设置在实施例所述的系统的被叫终端110中。
图10为本实施例提供的通话装置的结构示意图，如图10所示，本实施例提供的通话装置主要包括：发送模块112，用于向服务器130发送签到请求，其中，该签到请求中携带有被叫用户的ID，用于指示服务器130将被叫用户的ID与被叫终端130的通信标识关联；被叫用户的ID为被叫用户在服务器130上为被叫用户使用的第一电子签名设备140注册的唯一标识；接收模块114，用于接收到服务器130发送的呼叫请求，其中，该呼叫请求为主叫终端120对被叫用户的ID发起的呼叫请求；通话模块116，用于与主叫终端120建立通话链路，与主叫终端120进行通话。
采用本发明实施例提供的技术方案，被叫终端通过发送模块112向服务器130发送签到请求，请求将被叫用户的ID与被叫用户当前使用的被叫终端110的通信标识进行关联，在服务器130接收到呼叫该被叫用户的ID时，呼叫被接续到该被叫终端110上。因此，被叫用户的ID并不会固定的与一个终端进行绑定，通过第一电子签名设备140，可以方便的将被叫用户的ID与不同终端进行关联，从而使得即使使用固定电话，用户也可以通过同一ID使用不同的终端接听电话，实现了固定电话的移动性。并且，对于移动终端，用户也不必像现有技术中一般，无论到什么地方都需要携带安装SIM卡的移动终端，只需要携带存储ID的第一电子签名设备140即可。另外，采用本发明实施例提供的技术方案，用户可以通过同一ID方便的使用任意终端(包括固定终端和移动终端，即被叫终端110可以是固定终端也可以是移动终端)接听电话，不同的用户也可以通过同一终端接听电话，提高了设备的利用率。
在本发明实施例的一个可选实施方案中，该通话装置还可以包括：第一获取模块，用于从与被叫终端110连接的第一电子签名设备获取被叫用户的ID。通过第一电子签名设备140存储被叫用户的ID，可以方便的将被叫用户的ID与不同终端进行关联，从而使得即使使用固定电话，用户也可以通过同一ID使用不同的终端接听电话，实现了固定电话的移动性。
在本发明实施例的一个可选实施方案中，该通话装置还可以包括：认证模块，用于对第一电子签名设备140进行身份认证。在该可选实施方式中，认证模块可以预先保存被叫 用户的公钥，在从第一电子签名设备140获取被叫用户的ID时，可以指示第一电子签名设备140发送身份认证数据，第一电子签名设备140接收到指示后，利用保存在私钥对待签名数据进行签名后得到身份认证数据，将身份认证数据发送给认证模块，认证模块利用公钥对身份认证数据进行认证，并在认证通过后，可以使用第一电子签名设备140中存储的被叫用户的ID。其中，在该可选实施方式中，待签名数据可以是认证模块发送给第一电子签名设备140的，也可以是第一电子签名设备140自己确定的，这种情况下，第一电子签名设备140可以将待签名数据的明文与身份认证数据一起发送给认证模块。当然，认证模块对第一电子签名设备140进行身份认证还可以是其他形式的认证，例如通过密码方式进行认证等。

具体的，主叫终端可以通过如下方式之一获取到被叫用户的ID：主叫用户通过主叫终 端的输入装置向主叫终端输入被叫用户的ID，主叫用户通过语音方式向主叫终端输入被叫用户的ID等。
其中，被叫用户的ID为被叫用户在服务器上为被叫用户使用的第一电子签名设备注册的唯一标识；在注册时，第一电子签名设备保存被叫用户的ID，ID可以是但不限于以下方式：数字、字母、字符、汉字之一或其组合。该ID相当于现有通信系统中用户的电话号码，方便主叫终端呼叫被叫用户。
其中，第一电子签名设备包括但不限于具有安全芯片的电子签名钥匙(KEY设备，例如工行的U盾或农行的K宝等)、具有安全芯片的智能卡等，其中，安全芯片能够进行签名运算、加解密运算、协商传输密钥的功能。

在本发明实施例的一个可选实施方案中，本实施例的呼叫方法还可以包括主叫终端向服务器发起签到的步骤，具体包括：
主叫终端向服务器发送签到请求，签到请求中携带有主叫用户的ID，用于指示服务器将主叫用户的ID与主叫终端的通信标识关联；其中，主叫用户的ID为主叫用户在服务器上为主叫用户使用的第二电子签名设备注册的唯一标识。
在现有技术中，作为主叫，当用户不在其使用的电话机位置上时，比如用其他用户的电话拨打电话时，被叫用户则无法得知该电话是由该用户拨打的，有可能会不接或漏接，错过重要的电话，或给双方造成误解，对用户的工作或生活都会带来不便。通过本发明实施例的上述可选实施方式，即使主叫用户不是在其绑定的电话机拨打电话，但被叫显示的还是该主叫用户的ID，从而解决了被叫用户无法得知拨打该呼叫的主叫用户的身份的问题，从而提高了用户体验。
在本发明实施例的一个可选实施方案中，在主叫终端向服务器发送签到请求之前，本实施例的呼叫方法还包括：从与主叫终端连接的第二电子签名设备获取主叫用户的ID。从主叫终端获取到主叫用户的ID，主叫用户无需记忆该ID，方便用户使用，提高用户体验。
其中，第二电子签名设备包括但不限于具有安全芯片的电子签名钥匙(KEY设备，例 如工行的U盾或农行的K宝等)、具有安全芯片的智能卡等，其中，安全芯片能够进行签名运算、加解密运算、协商传输密钥的功能。第二电子签名设备在服务器注册时，将服务器侧分配的唯一标识即ID保存。
在本发明实施例的一个可选实施方案中，本实施例的呼叫方法还包括：主叫终端在签到请求中携带身份认证数据，以实现服务器侧对主叫用户的身份认证，保证主叫用户身份的合法，进而保证通话安全。
其中，主叫终端在签到请求中携带身份认证数据可以通过但不限于如下方式之一实现：
方式一：作为一种可选的方式，如图14所示，在主叫终端向服务器发送签到请求时，主叫终端可以主动在签到请求中携带身份认证数据，具体包括：
S701：主叫终端从第二电子签名设备获取身份认证数据；
身份认证数据为第二电子签名设备对待签名数据进行签名获得的认证数据；其中，待签名数据包括主叫用户的ID和/或第二电子签名设备自己生成的单次认证数据，该单次认证数据可以为随机数和事件因子之一或其组合，其中事件因子可以为每生成一次累计+1或任意值等方式生成的。
S702：主叫终端在签到请求中携带身份认证数据并发送至服务器。
方式二：作为另一种可选的方式，如图15所示，在主叫终端向服务器发送签到请求时，主叫终端还可以根据服务器发送的待签名数据生成身份认证数据，携带在签到请求中，具体包括：

S803：主叫终端接收第二电子签名设备至少对待签名数据进行签名获得的身份认证数据，并在签到请求中携带身份认证数据并发送至服务器。
具体的，在本步骤中，除了对待签名数据进行签名外，还可以一并对主叫用户的ID进行签名。
在步骤S602之后，在步骤S603之前，作为本发明实施例的可选实施方式，本实施例的呼叫方法还包括验签的步骤，具体包括：主叫终端接收到服务器发送的验签请求；从第二电子签名设备获取签名数据，签名数据为第二电子签名设备对待签名数据进行签名获得的数据；将签名数据发送至服务器。
其中，待签名数据包括以下至少一项：第二电子签名设备生成的随机数、验签请求中 携带的待签名数据(如服务器生成的随机数)以及主叫用户的ID。
本实施例中，服务器在呼叫连通之前，会验证主叫用户是否在线，即主叫用户的第二电子签名设备是否与当前通信端口的终端连接，如果服务器可以获得通过第二电子签名设备对待签名数据进行签名的签名数据，则说明主叫用户在线，进一步地，通过签名数据可以验证主叫用户的身份是否合法，从而保证通话安全。
在本发明实施例的一个可选实施方案中，在主叫终端向服务器发送签到请求之后，本实施例的呼叫方法还包括：主叫终端向服务器发送释放签到请求，释放签到请求中携带有主叫用户的ID，用于指示服务器删除主叫用户的ID与主叫终端的通信标识的关联关系。由此，主叫终端可以释放签到，不影响被主叫用户签到的终端的正常使用。
其中，触发主叫终端向服务器发送释放签到请求之前，主叫终端还可以接收释放签到指令，具体包括以下方式的一种或多种：
方式一：主叫终端接收到主叫用户输入的释放签到指令，例如，主叫用户输入“9#”，表示主叫用户请求释放签到；
方式二：主叫终端接收到服务器发送的释放签到指令；
方式三：主叫终端接收到与其连接的第二电子签名设备的释放签到指令，例如，主叫用户按着第二电子签名设备上的C键断开第二电子签名设备与主叫终端的连接，这时，第二电子签名设备在与主叫终端断开连接时也会发出一个释放签到指令给主叫终端。
通过该可选实施例，用户可以在不使用某个终端时，释放与该终端的关联关系，从而使得其它用户可以使用该终端，提高了终端的利用率。
为了进一步保证通话安全，保证释放签到是由真实的主叫用户发起的，在本发明实施例的一个可选实施方案中，本实施例的呼叫方法还可以包括：主叫终端在释放签到请求中携带身份认证数据，以实现服务器侧对主叫用户的身份认证，保证通话安全。该释放签到请求中携带的身份认证数据可以与在签到请求中携带的身份认证数据以相同的机制生成，例如：
作为一种可选的方式，主叫终端主动在释放签到请求中携带身份认证数据，具体实现与图14所示的方式类似，只是将签到请求替换为释放签到请求，此处不再赘述。
作为另一种可选的方式，主叫终端还可以根据服务器发送的待签名数据生成身份认证数据，携带在释放签到请求中，具体实现与图15所示的方式类似，只是将签到请求替换为释放签到请求，此处不再赘述。
为了进一步保证通话双方的安全，在本发明实施例的一个可选实施方案中，本实施例的呼叫方法还包括：主叫终端与被叫终端协商传输密钥，并利用传输密钥对传输数据加解密的步骤，具体包括：
在与被叫用户使用的被叫终端建立通话链路之后，与被叫终端进行通话之前，主叫终端与被叫终端利用各自的电子签名设备协商传输密钥，主叫终端将传输密钥协商过程中接收到的信息发送给第二电子签名设备，指示第二电子签名设备根据接收到的信息获取传输密钥；
在与被叫终端进行通话的过程中，主叫终端将从被叫终端接收到的加密数据发送给第二电子签名设备，并接收第二电子签名设备通过传输密钥对接收到的加密数据进行解密后返回的明文数据；以及将需要发送给被叫终端的传输数据发送给第二电子签名设备，接收第二电子签名设备通过传输密钥对需要发送的传输数据进行加密后的返回的密文数据，并将密文数据发送给被叫终端。
在本发明实施例的一个可选实施方案中，本实施例的主叫终端还可以包括安全芯片，该安全芯片可以用于对第二电子签名设备进行身份认证，并将第二电子签名设备与对端协商的传输密钥保存，从而不需要第二电子签名设备就可以对传输数据进行加解密，提高了处理效率。

在本发明实施例的一个可选实施方案中，在与被叫终端进行通话结束之后，本发明实施例的呼叫方法还包括：将保存的传输密钥删除。由此，主叫终端将传输密钥删除后，不影响主叫终端的正常使用；同时也无法利用该主叫终端以保存的传输密钥冒充主叫用户进行加密通话了。
在本发明实施例的一个可选实施方案中，本实施例还可以在通话过程中，进行通话跳变，以防止电话被监听，将重要的通话信息泄露。通话跳变包括密钥跳变和/或线路跳变。

(1)方式一：
C1、终端(终端可以为被叫终端或者主叫终端)生成随机数R1；
C2、终端对随机数R1进行签名，生成签名值S1；
C3、终端将随机数R1、签名值S1以及终端的数字证书发送至电子签名设备(可以为第一电子签名设备或者第二电子签名设备)；
C4、电子签名设备利用预存的根证书校验接收的终端的数字证书的合法性，如果校验该终端的数字证书合法，则执行C5，如果校验该终端的数字证书不合法，则停止身份认证流程，必要时，可以向终端反馈校验证书不通过的消息；

当然，除了上述两种方式外，终端对电子签名设备进行身份认证还有其他方式，本领域技术人员在本发明基础上扩展的其他身份认证方式都应该是本发明的保护范围。
在实施例10和实施例11中，当主叫终端或者被叫终端具有安全芯片时，在终端与电子签名设备完成了身份认证之后，终端与电子签名设备之间还可以协商出一个传输密钥，并将该传输密钥发送至服务器，服务器保存该传输密钥，用于后续终端、服务器以及电子签名设备之间数据传输的加/解密。主叫终端和被叫终端所协商出的传输密钥可以是相同的密钥，也可以是不同的密钥。当服务器与主叫终端之间进行通信时，利用主叫终端的传输密钥对信息进行加/解密；当服务器与被叫终端之间进行通信时，利用被叫终端的传输密钥对信息进行加/解密。当然，当电子签名设备需要向服务器进行签到时，可以在向服务器发送签到请求的同时发送协商密钥至服务器；在其他场合，向终端发送传输密钥也可以单独完成。
在具体的实施方式中，上述过程均可以采用至少如下六种方式进行：
(1)方式一：
E1、终端(终端可以为被叫终端或者主叫终端)生成随机数R3，利用电子签名设备的公钥对随机数R3加密生成R3的密文，并将R3的密文发送至电子签名设备；

E3、终端利用私钥解密获得R4，利用R3和R4生成传输密钥(该生成密钥的过程与 电子签名设置生成密钥的过程相同，例如连接R3和R4成为传输密钥)；
E4、终端向服务器发送签到请求，当然，终端也可以不在发送签到请求的情况下单独发送保存传输密钥的请求，例如，当电子签名设备不需要向服务器签到时，则不需要发送签到请求，此时仅需要单独发送保存传输密钥的请求；
E5、服务器生成待签名信息，该待签名信息可以是随机数或其他因子，发送签名指令(用于指示电子签名设备对该待签名信息进行签名)和该待签名信息发送至电子签名设备；
E6、电子签名设备利用服务器的公钥对传输密钥进行加密，并对待签名信息和加密后的传输密钥进行签名生成签名值S3，将签名值S3和加密后的传输密钥发送至服务器；
E7、服务器对签名值S3进行验签，如果验签通过，则服务器利用私钥解密获得传输密钥，保存传输密钥。该传输密钥与电子签名设备的ID一一对应。
(2)方式二：
与方式一不同的是，方式二中是由电子签名设备生成传输密钥发送至终端，具体过程如下：
F1、电子签名设备生成传输密钥，该传输密钥用于后续与终端之间通信的加/解密，电子签名设备利用终端的公钥将该传输密钥进行加密，将加密后的传输密钥发送至终端；

实施例12
图17示出了本发明实施例的一种呼叫方法，该呼叫方法可以采用上述的服务器130实现，参见图17，本发明实施例的呼叫方法，包括下述步骤S1001～S1003：其中：
S1001：服务器接收到被叫终端发送的签到请求，签到请求中包括被叫用户的ID；被叫用户的ID为被叫用户在服务器上为被叫用户使用的第一电子签名设备注册的唯一标识。
具体的，用户在服务器上为用户使用的电子签名设备进行注册，从而使得电子签名设备具有唯一标识，将该唯一标识作为用户的ID。ID可以是但不限于以下方式：数字、字母、字符、汉字之一或其组合。该ID相当于现有通信系统中用户的电话号码，方便主叫终端呼叫被叫用户。在进行呼叫时，可以仅提供用户的ID给服务器，服务器即可以知晓主叫用户和被叫用户为哪个。
在本发明实施例的一个可选实施方案中，用户使用电子签名设备箱服务器提出注册申请，服务器可以向电子签名设备办法证书或者使用电子签名设备内已有的其他认证单位办法的证书，服务器为用户分配一个唯一标识作为用户的ID，并将用户的ID与颁发给电子签名设备的证书绑定存储，由此，服务器可以通过为电子签名设备颁发的证书来验证电子签名设备的身份。具体的，可以通过但不限于如下方式之一进行注册：
方式一：用户持电子签名设备向服务器发送账号申请，服务器审核用户身份通过后，向电子签名设备发送密钥生成指令，电子签名设备生成密钥对，并将公钥发送至服务器，服务器生成电子签名设备的公钥证书，分配唯一标识作为用户的ID，将用户的ID与公钥证书绑定存储，并为电子签名设备签发证书，并将签发的证书发送至电子签名设备，电子签名设备保存服务器签发的证书。通过此种方式，由电子签名设备生成密钥对，保证密钥的安全性。
方式二：用户持电子签名设备向服务器发送账号申请，服务器审核用户身份通过后，向电子签名设备发送读取证书指令，电子签名设备将证书发送至服务器，服务器验证证书的合法性，并在证书合法后，分配唯一标识作为用户的ID，将用户的ID与证书绑定存储。通过此种方式，利用电子签名设备已有的证书进行绑定，提高了注册效率。
在具体使用时，被叫用户需要在使用的终端上，向服务器发送签到请求，该签到请求中至少包括被叫用户的ID，以告知服务器被叫用户使用的是哪一个终端，以便服务器确定被叫终端。
当然，为了保证被叫用户身份合法，在本发明实施例的一个可选实施方案中，在本步骤中，被叫终端在发送签到请求时，除了携带被叫用户的ID外，还可以在签到请求中携带身份认证数据并发送至服务器，以便服务器对被叫用户的身份进行认证，保证被叫身份合法。该身份认证数据可以通过如下方式之一得到：
方式一：第一电子签名设备对被叫用户的ID进行签名获得的签名数据。
方式二：第一电子签名设备待签名数据进行签名获得的签名数据，该待签名数据可以包括单次认证数据，该单次认证数据可以为第一电子签名设备生成的，也可以为被叫终端接收到服务器发送的并发送至第一电子签名设备的。该单次认证数据可以为随机数和事件因子之一或其组合，其中事件因子可以为每生成一次累计+1或任意值等方式生成的。
方式三：第一电子签名设备对待签名数据和被叫用户的ID进行签名获得的签名数据。
方式四：第一电子签名设备在注册时设置的密码或者与第一电子签名设备关联的动态口令牌生成的动态密码。
S1002：将被叫用户的ID与被叫终端的通信标识进行关联并存储；
具体的，服务器在收到被叫终端发送的被叫用户的ID后，将被叫用户的ID与被叫终端的通信标识进行关联并存储，由此，服务器可以知晓被叫用户使用的终端，以便找到被叫用户。该被叫终端的通信标识可以为固定电话的端口号、网络电话的IP地址、SIM的鉴权密钥等。
另外，在本发明实施例的一个可选实施方案中，在步骤S1001中，如果被叫终端在发送的签到请求中携带了身份认证数据，在服务器收到被叫终端的签到请求之后，本步骤中，服务器还可以对接收到的被叫终端发送的身份认证数据进行认证，并在认证通过后，执行将被叫用户的ID与被叫终端的通信标识进行关联并存储的步骤。具体的，服务器可以通过被叫用户在服务器上为第一电子签名设备注册时存储的第一电子签名设备的公钥对签名数据进行验签的方式进行身份认证，也可以验证静态密码或者动态密码的方式进行身份认证。由此保证只有在认证被叫用户身份合法后，才执行将被叫用户的ID与被叫终端的通信标识进行关联并存储的步骤，保证被叫用户签到的合法性。
当然，在本发明实施例的一个可选实施方案中，在本步骤S1002，将被叫用户的ID与被叫终端的通信标识进行关联并存储之后，还可以包括，服务器删除被叫用户的ID与被叫终端的通信标识的关联关系。基于此，服务器可以释放对被叫用户的签到，不影响被被叫用户签到的终端的正常使用。当然，服务器可以通过如下方式至少之一触发释放对被叫用户的签到的流程：接收被叫终端发送的释放签到指令后、服务器判断需要释放签到后。
在本发明实施例的一个可选实施方案中，如果服务器接收到被叫终端发送的释放签到指令，则服务器还可以对被叫用户的身份进行验证，以保证释放签到的被叫用户身份合法。此时，服务器可以接收被叫终端返回的身份认证数据，并进行身份认证，在身份认证通过后，执行服务器删除被叫用户的ID与被叫终端的通信标识的关联关系的步骤。具体的，被叫终端返回的身份认证数据可以采用与被叫终端发送签到请求时相同的方式生成，服务器可以采用对应的认证方法进行认证，在此不再赘述。
S1003：在接收到主叫终端对被叫用户的ID的呼叫请求后，根据被叫用户的ID与被叫终端的通信标识的关联关系，建立主叫终端与被叫终端的通话链路。
具体的，服务器在接收到主叫终端对被叫用户的ID的呼叫请求后，可以依据存储的被叫用户的ID与被叫终端的通信标识的关联关系，查找到被叫终端的通信标识，从而确定被叫终端的位置，建立主叫终端与被叫终端的通话链路。由此可以实现只要被叫用户的ID与被叫终端的通信标识进行了关联，即可以找到被叫用户的位置。
另外，在本发明实施例的一个可选实施方案中，在本步骤中，在接收到主叫终端对被叫用户的ID的呼叫请求后，服务器还可以向被叫终端发送验签请求，在接收到被叫终端返回的签名数据后进行验签，并在验签通过后，执行建立主叫终端与被叫终端的通话链路的步骤。具体的，该验签请求可以为单次签名数据，例如随机数和/或事件因子等。服务器只有在被叫终端返回签名数据并验签通过后才建立主叫终端与被叫终端的通话链路，由此验证了被叫用户是否在线，保证接听电话的用户确实为被叫用户本人，防止非被叫用户本人接听电话，提高了呼叫的安全性。
此外，在本发明实施例的一个可选实施方案中，在本步骤中，在接收到主叫终端对被叫用户的ID的呼叫请求之后，服务器还可以判断呼叫请求的类型为预设的呼叫请求类型，执行建立主叫终端与被叫终端的通话链路的步骤。由此，服务器可以兼容现有的通话系统，不影响正常使用，即使被叫终端已经进行了签到，也不影响正常接入该被叫终端的呼叫。
具体的，服务器可以判断接收到的主叫终端的呼叫请求的类型，判断其为被叫用户的ID，还是普通电话号码，如果为普通电话号码，则将主叫终端的呼叫接入至普通电话号码对应的被叫终端上，建立主叫终端与普通电话号码对应的被叫终端的通话链路；如果为被叫用户的ID，则将主叫终端的呼入接入至被叫用户的ID签到的被叫终端上，建立主叫终端与关联了被叫用户的ID的终端通信标识对应的终端的通话链路。
由此可见，通过本发明实施例的呼叫方法，由于被叫终端向服务器发送了签到请求，告知服务器被叫用户使用的是哪一个终端，服务器由此可以将该终端与被叫用户进行关联，由此可以在接收到主叫终端对被叫用户的呼叫时，将主叫终端接入被叫用户签到的终端上，由此可以保证被叫用户无论使用哪一个终端，只要在该终端处进行了签到，就可以找到该被叫用户，方便了使用。
此外，为了可以在被叫终端处知晓主叫的身份，在本发明实施例的一个可选实施方案中，还可以在被叫终端处显示主叫的来电显示，此时，服务器还可以接收到主叫终端发送的签到请求，签到请求中携带有主叫用户的ID；将主叫用户的ID与主叫终端的通信标识进行关联并存储。由此，服务器可以在主叫发起对被叫用户的ID的呼叫请求时，知晓主叫用户的身份。
当然，为了保证主叫用户身份的合法，在本发明实施例的一个可选实施方案中，在服务器收到主叫终端的签到请求之后，服务器还可以对接收到的主叫终端发送的身份认证数据进行认证，并在认证通过后，执行将主叫用户的ID与主叫终端的通信标识进行关联并存储的步骤。主叫终端发送的身份认证数据可以采用与被叫终端发送签到请求时相同的方式生成，服务器可以采用对应的认证方法进行认证，在此不再赘述。
当然，在本发明实施例的一个可选实施方案中，服务器在将主叫用户的ID与主叫终端的通信标识进行关联并存储之后，还可以删除主叫用户的ID与主叫终端的通信标识的关联关系。基于此，服务器可以释放对主叫用户的签到，不影响被主叫用户签到的终端的正常使用。当然，服务器可以通过与被叫终端释放签到相同的方式释放对主叫用户的签到，在此不再赘述。
在本发明实施例的一个可选实施方案中，如果服务器接收到主叫终端发送的释放签到指令，则服务器还可以对主叫用户的身份进行验证，以保证释放签到的主叫用户身份合法。此时，服务器可以接收主叫终端返回的身份认证数据，并进行身份认证，在身份认证通过后，服务器删除主叫用户的ID与主叫终端的通信标识的关联关系的步骤。具体的，主叫终端返回的身份认证数据可以采用与被叫终端返回身份认证数据的方式相同，服务器可以采用对应的认证方法进行认证，在此不再赘述。
另外，在本发明实施例的一个可选实施方案中，在接收到主叫终端对被叫用户的ID的呼叫请求后，服务器还可以向主叫终端发送验签请求，在接收到主叫终端返回的签名数据后进行验签，并在验签通过后，执行建立主叫终端与被叫终端的通话链路的步骤。具体的，该验签请求可以为单次签名数据，例如随机数和/或事件因子等。服务器只有在主叫终端返回签名数据并验签通过后才建立主叫终端与被叫终端的通话链路，由此验证了主叫用户身份的真实性，保证拨打电话的用户确实为主叫用户本人，防止非主叫用户本人拨打电话，提高了呼叫的安全性。
为了保证主叫终端与被叫终端的通话的安全性，主叫终端与被叫终端之间的通话数据或者其他数据可以经由传输密钥进行加密后在线路上传输。
在本发明实施例的一个可选实施方案中，具体的，服务器可以通过如下方式之一保证主叫终端与被叫终端之间通话的安全性：
方式一：服务器可以接收被叫终端发送的第一传输密钥并保存第一传输密钥，以及接收主叫终端发送的第二传输密钥并保存第二传输密钥；利用第一传输密钥对与被叫终端之间的传输数据进行加密或解密，以及利用第二传输密钥对与主叫终端之间传输数据进行加密或解密。通过此种方式，服务器还可以接收主叫终端发送来的加密数据，解密后再加密发送至被叫终端，也可以接收被叫终端发送来的加密数据，解密后再加密发送至主叫终端， 由于主叫终端与被叫终端分别采用了不同的传输密钥，防止破解，保证了主叫终端与被叫终端之间通话的安全性，同时，如果通话双方的某一方释放了签到，还不影响另一方正常使用自己的传输密钥。
方式二：服务器也可以将主叫终端发送来的传输密钥发送至被叫终端，此时，经由主叫终端发送来的加密数据，可以由服务器直接发送至被叫终端，而不需要经服务器解密再加密后发送，提高数据的传输效率，减少服务器的工作负担。
当然，在本发明实施例的一个可选实施方案中，服务器还需要删除第一传输密钥和/或第二传输密钥。此时，触发服务器删除第一传输密钥和/或第二传输密钥的触发时机可以包括但不限于如下至少一种方式：
服务器接收到主叫终端发送的释放签到指令、服务器接收到被叫终端发送的释放签到指令、本次通话完成之后(例如挂机)、和服务器根据预设的规则判断出需要删除(例如：服务器判断预设时间到即删除等)等。
当然，在本发明实施例的一个可选实施方案中，如果服务器主动发起(例如服务器根据预设的规则判断)删除第一传输密钥和/或第二传输密钥时，还可以向被叫终端和/或主叫终端发送密钥删除请求，用于指示被叫终端和/或主叫终端删除保存的传输密钥。此时，被叫终端和/或主叫终端可以删除保存在终端内的传输密钥，也可以指示与其连接的电子签名设备删除保存在电子签名设备内的传输密钥，例如：被叫终端指示第一电子签名设备删除保存在第一电子签名设备内的传输密钥。
此外，在本发明实施例的一个可选实施方案中，如果服务器经由接收到终端发送的释放签到指令后触发删除第一传输密钥和/或第二传输密钥时，服务器还可以对终端的用户的身份进行验证，以保证释放签到的用户身份合法。例如：服务器可以接收被叫终端返回的身份认证数据，并进行身份认证，在身份认证通过后，删除第一传输密钥。当然，主叫终端发送释放签到指令时，也可以采用相同的方式触发服务器删除第二传输密钥。具体的，终端返回的身份认证数据可以采用与终端发送签到请求时相同的方式生成，服务器可以采用对应的认证方法进行认证，在此不再赘述。
在本发明实施例中，为了进一步保证主叫终端与被叫终端通话的安全性，在本发明实施例的一个可选实施方案中，在主叫终端与被叫终端进行通话的过程中，服务器还可以根据预设的跳变规则将当前的第一传输密钥跳变为新的第一传输密钥并利用新的第一传输密钥对传输数据进行加密或解密；和/或根据预设的跳变规则将当前的第二传输密钥跳变为新的第二传输密钥并利用新的第二传输密钥对传输数据进行加密或解密。由此可以保证在通话过程中不再使用单一的传输密钥，采用变化的传输密钥来提高传输密钥的安全性，防止被破解，从而提高通话的安全性。
具体的，服务器根据预设的跳变规则将当前的第一传输密钥跳变为新的第一传输密钥，和/或，将当前的第二传输密钥跳变为新的第二传输密钥，包括但不限于如下以下至少之一：
方式一：根据跳变触发因子，将当前的第一传输密钥跳变为新的第一传输密钥，和/或，将当前的第二传输密钥跳变为新的第二传输密钥；具体的，该跳变触发因子，包括以下至少之一：跳变周期、跳变时间点、和通话数据量等。即服务器可以预先与主叫终端和/或被叫终端协商出跳变周期，之后可以根据跳变周期进行密钥跳变，服务器也可以预先与主叫终端和/或被叫终端协商出跳变时间点，之后可以根据跳变时间点进行密钥跳变，服务器还可以与主叫终端和/或被叫终端预先协商出通话数据量，之后可以根据通话数据量进行密钥跳变。

在本发明实施例中，为了进一步保证主叫终端与被叫终端通话的安全性，在本发明实施例的一个可选实施方案中，在主叫终端与被叫终端进行通话的过程中，服务器还可以根据预设的线路跳变规则将当前的传输线路跳变为新的传输线路，并利用新的传输线路对传输数据进行传输。由此可以保证传输线路的安全性，防止通话被监听。具体的，服务器可以预先存储有通话线路池，服务器可以根据预设的跳变规则在通话线路池中选择与本通话线路不同的线路进行数据传输。该预设的跳变规则可以包括但不限于如下方式至少之一：
方式一：根据跳变触发因子，将当前的传输线路跳变为新的传输线路。具体的，该跳变触发因子，包括以下至少之一：跳变周期、跳变时间点、和通话数据量等。即服务器可以预先设置跳变周期，之后可以根据跳变周期进行密钥跳变，服务器也可以预先设置跳变时间点，之后可以根据跳变时间点进行密钥跳变，服务器还可以预先设置通话数据量，之后可以根据通话数据量进行密钥跳变。
方式二：获取到线路跳变指令，将当前的传输线路跳变为新的传输线路。具体的，线路跳变指令包括以下至少之一：被叫终端和/或主叫终端发送的跳变指令、和根据预设规则生成的线路跳变指令。即服务器可以接收被叫终端和/或主叫终端发送的线路跳变指令，并在接收到线路跳变指令后进行线路跳变；服务器还可以自主生产线路跳变指令，例如：服务器判断可以进行线路跳变(例如周期到、时间点到、数据量到、有监听等)后，进行线 路跳变。
另外，在本发明实施例的一个可选实施方案中，本发明实施例还提供一种多方通话的呼叫方法，由此，可以令多方通话的被叫用户可在任一位置接听电话，此时，被叫用户包括多个，呼叫请求中携带有各个被叫用户的ID；服务器根据被叫用户的ID与被叫终端的通信标识的关联关系，建立主叫终端与被叫终端的通话链路可以通过但不限于如下方式实现：
服务器向各个被叫用户的ID关联的通信标识对应的被叫终端发送多方通话请求；接收到多个被叫终端中的一个或多个返回的确认响应后，建立主叫终端与一个或多个被叫终端、以及一个或多个被叫终端之间的通话链路。
由此，服务器基于被叫用户可以在任一位置接听电话的基础上，实现了多方通话。
此外，为了保证多方通话的安全性，对主叫终端与一个或多个被叫终端、或者多个被叫终端之间的通话数据进行加密，此时，建立主叫终端与一个或多个被叫终端、以及一个或多个被叫终端之间的通话链路之前，服务器还可以接收主叫终端发送的共享传输密钥；将共享传输密钥发送至一个或多个被叫终端。基于此，主叫终端与被叫终端可以利用共享传输密钥进行通话数据的加密传输，保证了通话数据的安全性。
在上述实施例10至实施例12中，作为本发明实施例的一个可选实施方案，终端(即主叫终端120和被叫终端110)可以与电子签名设备间通过无线方式连接，也可以通过有线方式连接，无线方式可以包括：蓝牙、WIFI、NFC、红外或RFID等方式；有线方式可以包括：USB、音频(耳机插头)RJ11、RJ45或串口等方式。另外，如果通话数据需要加密，那么在本发明实施例中，可以通过如下方式实现通话：
方式一：终端可以通过与终端连接的电子签名设备进行加解密操作。例如：终端通过其网络接口(例如电话端口、SIM卡的鉴权密钥、IP地址等)接收加密后的通话数据，将加密后的通话数据发送至电子签名设备，由电子签名设备解密后发送至终端，再由终端送至听筒供用户收听；终端接收到用户通过麦克输入的语音数据，再发送至电子签名设备，由电子签名设备加密后发送至终端，再由终端经由网络接口外发。
方式二：数据可以均由电子签名设备发送至网络，再由终端收听语音数据和/或采集语音数据。例如：电子签名设备通过其网络接口接收加密后的通话数据，将加密后的通话数据进行解密并经由电子签名设备与终端的连接发送至终端，再由终端发送至听筒供用户收听；终端接收到用户通过麦克输入的语音数据，再经由与电子签名设备的连接发送至电子签名设备，经由电子签名设备加密后通过电子签名设备的网络接口外发。

其中，终端还需发送KEY的数字证书至服务器，如果在步骤S1204中对终端自身生成的随机数签名，则签到请求中还需携带终端自身生成的随机数，以便服务器进行身份认证。
S1207：服务器对接收到的终端发送的身份认证数据进行认证；
其中，服务器对身份认证数据进行认证，具体包括：校验终端发送的证书以及校验签名后的身份认证数据，此为现有技术，这里不再赘述。
S1208：服务器在认证通过后，将用户的ID与终端的通信标识进行关联并存储。
通过本实施例中提供的方法，用户只要随身携带其KEY，将其KEY连接到任意一个终端上，这个终端在服务器签到后，即服务器将用户的ID与终端的通信标识关联后，该终端就可以接收到其他终端对该用户的ID的呼叫，在呼叫其他终端时，在对端的来电显示也是该用户的ID，从而利用KEY实现移动接听或拨打电话。并且，在签到时，服务器可以通过主被叫终端发送的身份认证数据验证主被叫用户的身份是否合法，以保证与终端的通信标识关联的ID的身份合法性，从而保证通话安全。
如图20所示，本实施例提供了一种发起释放签到的流程，终端包括主叫终端和/或被叫终端，相应的，用户包括主叫用户和/或被叫用户，电子签名设备以KEY为例，具体包括以下步骤：
S1301：终端接收到释放签到指令；
其中，释放签到的发起方可以是通话的一方，也可以是服务器。终端接收到释放签到指令，具体包括以下方式的一种或多种：
方式一：主叫终端接收到主叫用户输入的释放签到指令，例如，主叫用户输入“9#”，表示主叫用户请求释放签到；
方式二：主叫终端接收到服务器发送的释放签到指令；
方式三：主叫终端接收到与其连接的第二电子签名设备的释放签到指令，例如，主叫用户按着第二电子签名设备上的C键断开第二电子签名设备与主叫终端的连接，这时，第二电子签名设备在与主叫终端断开连接时也会发出一个释放签到指令给主叫终端。
S1302：终端向服务器发送释放签到指令；
S1303：服务器向终端返回待签名数据；
其中，待签名数据中包含服务器生成的随机数。
S1304：终端将待签名数据发送至与其连接的KEY；
S1305：KEY对服务器发送的随机数、用户的ID或KEY自身生成的随机数之一进行签名得到身份认证数据；
其中，用户的ID为用户在服务器上为用户使用的KEY注册的唯一标识。在注册时，KEY保存用户的ID；
S1306：KEY将身份认证数据以及用户的ID发送至终端；
其中，KEY还需发送其数字证书至终端，如果在步骤S1304中对终端自身生成的随机数签名，则KEY还需将终端自身生成的随机数发送至终端。
S1307：终端向服务器发送释放签到请求，释放签到请求中携带身份认证数据；
其中，终端还需发送KEY的数字证书至服务器，如果在步骤S1304中对终端自身生成的随机数签名，则释放签到请求中还需携带终端自身生成的随机数，以便服务器进行身份认证。
S1308：服务器对接收到的终端发送的身份认证数据进行认证；
其中，服务器对身份认证数据进行认证，具体包括：校验终端发送的证书以及校验签名后的身份认证数据，此为现有技术，这里不再赘述。
S1309：服务器在身份认证通过后，删除用户的ID与终端的通信标识的关联关系。
其中，如果终端具有安全芯片，则在步骤S1303中服务器向终端返回待校验数据，步骤S1304～S1306合为一步，均由终端执行，无需发给KEY进行签名，终端的安全芯片可以对服务器发送的待校验数据加密得到身份认证数据。步骤S1308中，服务器对身份认证数据进行认证，即利用对称密钥对身份认证数据解密
通过本实施例中提供的方法，用户可以在不使用某个终端时，释放与该终端的关联关系，从而使得其它用户可以使用该终端，提高了终端的利用率。并且，在释放签到时，服务器可以通过主被叫终端发送的身份认证数据验证主被叫用户的身份是否合法，以保证释放签到的发起者的身份是安全的，以防止被恶意释放签到的情况。

实施例17
图26示出了本发明实施例的一种签到方法，应用于服务器侧，参见图26，本发明实施例的签到方法，包括下述步骤S1901～S1902：其中：
S1901：服务器接收到终端发送的通信标识和签到请求，签到请求中包括用户ID；用户ID为用户在服务器上为用户使用的第一电子签名设备注册的唯一标识。
具体的，用户在服务器上为用户使用的电子签名设备进行注册，从而使得电子签名设备具有唯一标识，将该唯一标识作为用户ID。用户ID可以是但不限于以下方式：数字、字母、字符、汉字之一或其组合。该用户ID相当于用户的身份识别号码。在进行签到时， 用户需要在使用的终端上，向服务器发送签到请求，该签到请求中至少包括用户ID，以使得服务器可以知晓正在使用终端的用户的身份。此外，终端还发送通信标识，通信标识为终端在服务器上的通信标识，服务器可通过该通信标识寻找到终端，通信标识可以为终端的端口号(如固定电话的端口号)、IP地址/MAC地址(PC等的IP地址/MAC地址)、SIM卡的鉴权密钥(如移动终端的SIM卡)等，以便告知服务器用户使用的是哪一个终端，以便服务器确定终端。本实施例中，电子签名设备包括但不限于具有安全芯片的电子签名钥匙(KEY设备，例如工行的U盾或农行的K宝等)、具有安全芯片的智能卡等，其中，安全芯片能够进行签名运算、加解密运算、协商传输密钥的功能。
当然，为了保证用户身份合法，在本发明实施例的一个可选实施方案中，在本步骤中，终端在发送签到请求时，除了携带用户ID外，还可以在签到请求中携带用户身份认证数据并发送至服务器，以便服务器对用户的身份进行认证，保证身份合法，服务器在对用户身份认证数据进行认证后，再执行将用户ID与终端的通信标识进行关联并存储的步骤。其中，用户身份认证数据是电子签名设备对待签名数据签名得到的，待签名数据可以通过如下方式之一得到：
方式一：待签名数据可以就是用户ID。
方式二：待签名数据可以包括单次认证数据，该单次认证数据可以为电子签名设备生成的，也可以为终端接收到服务器发送的并发送至电子签名设备的。该单次认证数据可以为随机数和事件因子之一或其组合，其中事件因子可以为每生成一次累计+1或任意值等方式生成的。
方式三：方式二中的单次认证数据和用户ID的组合。
方式四：电子签名设备在注册时设置的密码或者与电子签名设备关联的动态口令牌生成的动态密码。
S1902：将用户ID与终端的通信标识进行关联并存储；
具体的，服务器在收到终端发送的用户ID后，将用户ID与终端的通信标识进行关联并存储，由此，服务器可以知晓用户使用的终端，以便通知终端开启用户请求使用的业务。在用户不携带需要使用电子设备情况下，只要随身携带电子签名设备，与任意终端连接，在服务器上签到关联终端的通信标识与用户的ID，服务器便可以将该用户ID的业务接续到用户当前签到的终端上，从而使得用户可以使用同一ID在任何终端上实现其请求的业务。为用户对电子设备的使用提供了便捷。
另外，在本发明实施例的一个可选实施方案中，在步骤S1901中，如果终端在发送的签到请求中携带了用户身份认证数据，在服务器收到终端的签到请求之后，本步骤中，服务器还可以对接收到的终端发送的用户身份认证数据进行认证，并在认证通过后，执行将 用户ID与终端的通信标识进行关联并存储的步骤。具体的，服务器可以通过用户在服务器上为电子签名设备注册时存储的电子签名设备的公钥对签名数据进行验签的方式进行身份认证，也可以验证静态密码或者动态密码的方式进行身份认证。由此保证只有在认证用户身份合法后，才执行将用户ID与终端的通信标识进行关联并存储的步骤，保证用户签到的合法性。
当然，在本发明实施例的一个可选实施方案中，服务器设定为，可以同时存储一个以上的用户ID与不同终端的通信标识的关联关系，用户可以在一个以上的不同终端进行签到，所有终端均开启用户请求使用的业务。进一步的，当服务器需要向用户正在使用的终端发出信息或建立进一步的通信联系时，可向一个以上的不同终端广播待响应信息，用户正在使用的终端根据待响应信息向服务器发出响应信息，服务器根据响应信息确定用户正在使用的终端，响应信息可以是前述可选实施方案中的用户身份认证数据。保障仅用户本人可以接收到服务器发出的信息或与服务器建立进一步的通信联系。
当然，在本发明实施例的一个可选实施方案中，服务器设定为仅可以存储一个用户ID与终端的通信标识的关联关系，即在本步骤S1902，将用户ID与终端的通信标识进行关联并存储之前，还可以包括，服务器检测用户ID是否已存在关联关系，如果用户ID已存在关联关系，则服务器需先解除关联关系，保障用户仅可同时使用一个终端设备，避免非法签到。可选的，在解除关联关系后，服务器向解除关联关系的终端发送删除关联信息，该终端根据删除关联信息关闭用户请求使用的功能。
当然，在本发明实施例的一个可选实施方案中，在本步骤S1902，将用户ID与终端的通信标识进行关联并存储之后，还可以包括，服务器发送关联成功信息至终端。用于提示终端开启用户申请使用的功能，便于用户正常使用终端。
当然，在本发明实施例的一个可选实施方案中，在本步骤S1902，将用户ID与终端的通信标识进行关联并存储之后，还可以包括，服务器删除用户ID与终端的通信标识的关联关系。基于此，服务器可以释放对用户的签到，不影响被用户签到的终端的正常使用。当然，服务器可以通过如下方式触发释放对用户的签到的流程：接收终端发送的释放签到指令，服务器判断需要释放签到后：在本发明实施例的一个可选实施方案中，如果服务器接收到终端发送的释放签到指令，则服务器还可以对用户的身份进行验证，以保证释放签到的用户身份合法。此时，服务器可以接收终端返回的用户身份认证数据，并进行身份认证，在身份认证通过后，执行服务器删除用户ID与终端的通信标识的关联关系的步骤。具体的，终端返回的用户身份认证数据可以采用与终端发送签到请求时相同的方式生成，服务器可以采用对应的认证方法进行认证，在此不再赘述。
通过本实施例中提供的方法，在用户不携带需要使用电子设备情况下，只要随身携带 电子签名设备，与任意终端连接，在服务器上签到关联终端的通信标识与用户的ID，服务器便可以将该用户ID的业务接续到用户当前签到的终端上，从而使得用户可以使用同一ID在任何终端上实现其请求的业务，此外，本实施例中，通过终端对电子签名设备进行身份认证，服务器对终端及用户身份进行认证，在认证通过后，就可以利用电子签名设备使任意终端在服务器上获得权限，从而可将任意终端随时个人化。如用户在未携带个人电脑的情况下，可在任意终端上通过电子签名设备在服务器上获得终端与用户ID的关联，获得权限，进而使用用户已购买的收费软件，在结束使用时，使用电子签名设备结束终端与用户ID的关联(即释放签到)，不影响用户在其他终端上使用，在此情况下，公共终端可以预装任意收费软件，已购买权限的用户可使用用户ID与终端关联的方式使用收费软件。或者，用户可使用任意固定电话、PC或移动终端拨打或接听电话，通过电子签名设备在服务器上进行终端的通信标识与用户ID的关联，进而用该终端拨打或接听个人来电，无须携带手机。
实施例18
如图27所示，本实施例提供了一种签到方法，应用于终端侧，该签到方法可以通过实施例1中的终端实现，主要可以包括以下步骤：(S2001～S2002)
S2001：终端判断是否满足触发签到的规则；
在本发明实施例的一个可选实施方案中，终端判断是否满足签到的规则，其中，签到规则至少包含以下一项：终端接收到用户输入的签到指令；终端接收到服务器发送的签到指令；终端接收到与其连接的电子签名设备的签到指令。终端满足签到规则后向服务器发送通信标识和签到请求，可避免恶意签到。
S2002，在满足触发签到的规则后，终端向服务器发送通信标识和签到请求，签到请求中携带有用户ID，用于指示服务器将用户ID与终端的通信标识关联；
其中，用户ID为用户在服务器上为用户使用的电子签名设备注册的唯一标识；在注册时，电子签名设备保存用户ID，用户ID可以是但不限于以下方式：数字、字母、字符、汉字之一或其组合。该用户ID相当身份识别号码，方便服务器识别用户。电子签名设备包括但不限于具有安全芯片的电子签名钥匙(KEY设备，例如工行的U盾或农行的K宝等)、具有安全芯片的智能卡等，其中，安全芯片能够进行签名运算、加解密运算、协商传输密钥的功能。
通信标识为终端在服务器上的通信标识，服务器可通过该通信标识寻找到终端，通信标识可以为终端的端口号(如固定电话的端口号)、IP地址/MAC地址(PC等的IP地址/MAC地址)、SIM卡的鉴权密钥(如移动终端的SIM卡)等，以便告知服务器用户使用的是哪一个终端，以便服务器确定终端。
在本发明实施例的一个可选实施方案中，在步骤S2001之前，本实施例的签到方法还包括：终端获取用户ID。可选的，从与终端连接的电子签名设备获取用户ID，从终端获取到用户ID，用户无需记忆该ID，方便用户使用，提高用户体验(其中，该用户ID可以是电子签名设备存储的，也可以是电子签名设备接收用户通过键盘输入的)，或者，终端获取用户通过终端键盘输入的用户ID。
作为本发明实施例的一种可选方式，本实施例的签到方法还包括：终端在签到请求中携带用户身份认证数据，以实现服务器侧对用户的身份认证，保证用户身份的合法，进而保证终端使用的安全。身份认证数据是电子签名设备对待签名数据签名得到的。其中，待签名数据的获取方式与实施例1中待签名数据的获取方式相同，在此不再赘述。
作为本发明实施例的一种可选方式，本实施例的签到方法还包括：终端接收服务器发送的关联成功信息，终端根据该通知开启用户请求使用的业务。
作为本发明实施例的一种可选方式，在终端向服务器发送签到请求之后，本实施例的签到方法还包括：终端向服务器发送释放签到请求，释放签到请求中携带有用户ID，用于指示服务器删除用户ID与终端的通信标识的关联关系。由此，终端可以释放签到，不影响被用户签到的终端的正常使用。
其中，触发终端向服务器发送释放签到请求之前，终端还可以接收释放签到指令，具体包括以下方式的一种或多种：
方式一：终端接收到用户输入的释放签到指令，例如，用户输入“9#”，表示用户请求释放签到；
方式二：终端接收到服务器发送的释放签到指令；
方式三：终端接收到与其连接的电子签名设备的释放签到指令，例如，用户按着电子签名设备上的C键断开电子签名设备与终端的连接，这时，电子签名设备在与终端断开连接时也会发出一个释放签到指令给终端。
通过该可选实施例，用户可以在不使用某个终端时，释放与该终端的关联关系，从而使得其它用户可以使用该终端，提高了终端的利用率。
作为本发明实施例的一种可选方式，为了进一步保证安全，保证释放签到是由真实的用户发起的，本实施例的签到方法还包括：终端在释放签到请求中携带身份认证数据，以实现服务器侧对用户的身份认证，保证安全。该释放签到请求中携带的身份认证数据可以与在签到请求中携带的身份认证数据以相同的机制生成，在此不再赘述。
