具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
图1是本申请实施例的一个通信系统的网络架构示意图。如图1所示，通信系统100可以包括终端设备110和网络设备120。网络设备120可以通过空口与终端设备110通信。终端设备110和网络设备120之间支持多业务传输。
应理解，本申请实施例仅以通信系统100进行示例性说明，但本申请实施例不限定于此。也就是说，本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(Long Term Evolution，LTE)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、物联网(Internet of Things，IoT)系统、窄带物联网(Narrow Band Internet of Things，NB-IoT)系统、增强的机器类型通信(enhanced Machine-Type Communications，eMTC)系统、5G通信系统(也称为新无线(New Radio，NR)通信系统)，或未来的通信系统等。
在图1所示的通信系统100中，网络设备120可以是与终端设备110通信的接入网设备。接入网设备可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备110(例如 UE)进行通信。

例如，终端设备通过NR接口与接入网设备建立空口连接，用于传输用户面数据和控制面信令；终端设备可以通过NG接口1(简称N1)与AMF建立控制面信令连接；接入网设备例如下一代无线接入基站(gNB)，可以通过NG接口3(简称N3)与UPF建立用户面数据连接；接入网设备可以通过NG接口2(简称N2)与AMF建立控制面信令连接；UPF可以通过NG接口4(简称N4)与SMF建立控制面信令连接；UPF可以通过NG接口6(简称N6)与数据网络交互用户面数据；AMF可以通过NG接口11(简称N11)与SMF建立控制面信令连接；SMF可以通过NG接口7(简称N7)与PCF建立控制面信令连接。
图1示例性地示出了一个基站、一个核心网设备和两个终端设备，可选地，该无线通信系统100可以包括多个基站设备并且每个基站的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。
需要说明的是，图1只是以示例的形式示意本申请所适用的系统，当然，本申请实施例所示的方法还可以适用于其它系统。此外，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。还应理解，在本申请的实施例中提到的“指示”可以是直接指示，也可以是间接指示，还可以是表示具有关联关系。举例说明，A指示B，可以表示A直接指示B，例如B可以通过A获取；也可以表示A间接指示B，例如A指示C，B可以通过C获取；还可以表示A和B之间具有关联关系。还应理解，在本申请的实施例中提到的“对应”可表示两者之间具有直接对应或间接对应的关系，也可以表示两者之间具有关联关系，也可以是指示与被指示、配置与被配置等关系。还应理解，在本申请的实施例中提到的“预定义”或“预定义规则”可以通过在设备(例如，包括终端设备和网络设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现，本申请对于其具体的实现方式不做限定。比如预定义可以是指协议中定义的。还应理解，本申请实施例中，所述“协议”可以指通信领域的标准协议，例如可以包括LTE协议、NR协议以及应用于未来的通信系统中的相关协议，本申请对此不做限定。
为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范 围。本申请实施例包括以下内容中的至少部分内容。
零功耗通信技术在设备的功耗、尺寸以及成本等方面将具有显著优势。例如，零功耗通信技术从功耗上有望将设备功耗从窄带物联网(Narrow Band Internet of Things,NB-IoT)设备的数十毫瓦的功耗降低至几十微瓦甚至数微瓦；从成本上有望将设备成本从最便宜的NB-IoT设备的十几元降低至1元甚至更低。零功耗通信技术的主要特点是通过调制来波信号实现反向散射通信，同时它还可以通过能量采集获得能量以驱动数字逻辑电路或芯片(如微控制单元或传感器芯片)，实现对信号的编码、加密或简单计算等功能。
然而，零功耗通信技术中射频能量的转化效率往往不足10％，决定了驱动数字逻辑电路或芯片用于计算的功耗要求不能太高。虽然随着工艺的改进和设计的优化有所提高，每微焦耳能量可使用于计算的次数增多，但是仍不能满足复杂的计算。零功耗设备计算功能非常有限，无法支持如SHA-256定义的安全函数，更无法支持3GPP的认证机制。因此，零功耗设备或其他低能力设备如何对上行数据的传输进行授权，避免攻击者或者伪基站恶意触发设备的上行数据传输，保证上行传输数据的安全，是亟待解决的技术问题。
基于此，本申请实施例提供一种安全实现方法，参考图2所示，该方法包括但不限于以下步骤：
步骤210、第一设备获取第一网元的授权凭证；该授权凭证用于验证第一网元是否具有接收数据的权限；数据来自于与第一设备关联的至少一个第二设备；授权凭证包括第一数字签名。
步骤220、在基于第一数字签名对授权凭证验证通过的情况下，第一设备确定第一网元具有接收至少一个第二设备发送的数据的权限。
本申请实施例中，第一设备可以是支持设备认证机制算法的设备，例如，第一设备可以是用户设备UE，基站，以及其他可支持复杂运算的设备，本申请实施例对此不做限制。
第二设备可以是不支持设备认证机制算法的低运算能力的设备，即第二设备是无法单独进行安全运算的设备，例如，第二设备可以是零功耗设备(Zero Power Device，ZPD)，或者运算能力较弱的低能力设备，或者剩余电量较少的设备，本申请实施例对此不做限制。
本申请实施例中，由于第二设备的运算能力较低，因此，第二设备可以与第一设备进行绑定以形成关联关系，这样，第二设备可以利用其关联的第一设备的完备的运算能力和/或通信机制，实现对网络侧网元的授权。其中，第一设备可以与一个或者多个第二设备绑定。
可选地，第二设备可以与第一设备通过调制来波信号实现反向散射的技术进行通信。
另外，本申请实施例所提及的第一网元可以是网络侧网元，其中，第一网元可以是核心网网元、接入网网元、第三方应用网络中的网元等，本申请实施例对此不做限制。例如，第一网元可以是感知服务器，感知服务器可以是提供感知服务(例如定位、测速、健康呼救服务)的应用服务器。
可选地，当第一设备为UE时，第一网元可以为基站或应用服务器。当第一设备为基站时，第一网元可以为应用服务器。
本申请实施例中，第一设备可以获取第一网元的授权凭证，根据该授权凭证验证第一网元是否具有获取该第一设备关联的至少一个第二设备的数据的权限。其中，第一网元的授权凭证可以包括第一数字签名，第一设备可以利用第一数字签名来对授权凭证进行验证，以确定第一网元是否具有获取上述至少一个第二设备数据的权限。
可选地，本申请实施例中所提及的数据可以是第二设备的上行数据，该数据可以包括无线信号、反射信号、控制面数据、用户面数据等，本申请实施例对第二设备发送的数据不做限制，示例性的，第二设备作为感知设备时，该数据可以是感知数据。
可选地，第一设备确定第一网元具有获取其关联的至少一个第二设备的数据后，第二设备可以将产生的数据直接发送给第一网元，第二设备也可以将其产生的数据通过第一设备转发给第一网元，本申请实施例对此不做限制。
也就是说，第一网元可以接收第一设备发送的数据，该数据是至少一个第二设备发送给第一设备的，或者，第一网元可以接收至少一个第二设备发送的数据。
综上所述，本申请实施例提供的安全实现方法中，第一设备可以代理其关联的至少一个第二设备对第一网元的授权凭证进行验证。在验证通过的情况下，第一设备可以确定第一网元具有接收至少一个第二设备的数据的权限。这样，低运算能力的第二设备可以实现对网络侧的网元进行验证，避免第二设备数据传输过程中的窃取和泄露问题，保证了第二设备的数据传输的安全性。
可选地，第一数字签名可以是凭证发放设备的签名，也就是说，第一数字签名可以是利用凭证发放设备的私钥对授权凭证中的其他信息进行签名得到的。应理解，凭证发放设备是生成第一网元授权凭证的设备。
可选地，第一网元的授权凭证包括以下中的至少一项：业务标识信息、凭证发放设备的公钥、凭证发放设备的公钥、第一网元的标识信息、第一网元的公钥、第一网元对应的RSA累加器参数、数据标识信息。
其中，若第一网元根据业务需要而获取数据时，则第一网元的授权凭证中可以包括业务标识信息。该业务标识信息可以用于指示第一网元需要的数据对应的业务类型。其中，业务类型可以包括定位业务、测速业务、健康呼救业务、环境监测业务等，本申请实施例对此不做限制。
可选地，业务标识信息可以是一固定长度的比特数据，其中，不同比特数据对应不同的业务类型。第一设备通过查表的方式确定该比特数据对应的业务类型。
可选地，业务标识信息可以是第一网元的标识信息，一般来说，第一网元可以提供一种或多种业务，因此所需的业务类型不同。基于此，本申请实施例中可以通过第一网元的标识信息来表征数据的业务类型。
其中，第一网元对应的RSA累加器参数用于验证第一网元的授权凭证是否被撤销。应理解，实际应用中存在授权凭证被撤销的情况，因此，在授权凭证中需要携带该授权凭证的RSA参数，以供第一设备验证所获取的第一网元的授权凭证是否被撤销。
另外，数据标识信息，可以用于指示上述数据对应的数据类型，数据类型包括一种或多种。示例性的，如果业务为健康呼救业务，那么数据类型可以包括心率数据、体温数据、运动量数据、血压数据、呼吸频率数据等，如果业务为环境监测业务，那么数据类型可以包括位置数据、风速数据、温度数据、日晒数据、高度数据等。本申请实施例对数据类型不做限制。
需要说明的是，凭证发放设备可以在第一网元的请求下，为第一网元生成授权凭证。凭证发放设备可以是应用提供商证书颁发机构(Certificate Authority，CA)，也可以是业务服务器，也可以是运营商CA，本申请实施例对此不做限制。另外，第一网元请求凭证发放设备生成授权凭证的相关内容详见下文描述，为了简洁，此处不做赘述。
可选地，第一数字签名可以是利用凭证发放设备的私钥对上述信息中的全部内容或部分内容进行签名得到。对应的，参考图3所示，步骤220之前，还可以通过以下步骤实现对授权凭证的验证：
步骤230、第一设备利用凭证发放设备的公钥对第一数字签名进行验证，得到第一验证信息；
步骤240、若第一验证信息与授权凭证中除第一数字签名之外的其他信息一致，则确定授权凭证验证通过。
可以理解的是，既然第一数字签名是利用凭证发放设备的私钥签名得到，那么第一设备可以利用凭证发放设备的公钥对第一数字签名进行验证，得到第一验证信息。只有在第一验证信息与授权凭证中的其他信息一致，第一设备才可以确定第一网元具有获取至少一个第二设备的数据的权限。若不一致，则第一设备不进行进一步处理。
需要说明的是，第一设备可以从授权凭证中获取凭证发放设备的公钥，对第一数字签名进行验证。第一设备也可以提前存储凭证发放设备的公钥，利用预先存储的公钥对第一数字签名进行验证，本申请实施例对凭证发放设备的公钥来源不做限制。
可选地，在一些实施例中，授权凭证包括第一网元对应的RSA累加器参数时，步骤220中在基于第一数字签名对授权凭证验证通过的情况下，第一设备确定第一网元具有接收至少一个第二设备发送的数据的权限，还可以通过以下方式实现：
在基于第一数字签名对授权凭证验证通过的情况下，第一设备基于RSA累加器参数，验证第一网元的授权凭证是否被撤销；
若授权凭证未被撤销，则第一设备确定第一网元具有接收至少一个第二设备的数据的权限。
可以理解的是，在对第一网元的授权凭证验证通过之后，第一设备还可以根据RSA累加器参数验证该授权凭证是否被撤销。若第一网元的授权凭证未被撤销，则第一设备可以确定第一网元具有接收其关联的至少一个第二设备的数据的权限。若第一网元的授权凭证被撤销，则第一设备可以确定第一网元不具有获取第二设备的数据的权限。如此，可以提高第一设备针对第二设备上行数据的授权效率。
可选地，若第一网元的授权凭证中包括业务标识信息和/或数据标识信息，则在对授权凭证进行验证之前，第一设备还需要判断与其关联的第二设备是否支持该业务标识信息指示的业务类型，和/或数据标识信息指示的数据类型。
其中，授权凭证中携带的业务标识信息，可以用来表征第一网元需要获取的数据的业务类型。授权凭证中携带的数据标识信息，可以用来表征第一网元需要获取的数据的数据类型。因此，第一设备获取到第一网元的授权凭证之后，需要先判断与其关联的至少一个第二设备是否支持第一网元 所需的业务类型，和/或数据类型。
可选地，第一设备可以维护一份业务类型列表，该列表可以存储与其关联的每个第二设备的标识信息，以及每个第二设备支持的业务类型。这样，第一设备在获取到第一网元的授权凭证之后，可以将授权凭证中的业务标识信息对应的业务类型与上述列表中每个第二设备支持的业务类型进行对比，从而确定支持该业务类型的第二设备。
可选地，第一设备还可以维护一份数据类型列表，该列表可以存储与第一设备关联的每个第二设备的标识信息，以及每个第二设备支持的数据类型。这样，第一设备在获取到第一网元的授权凭证之后，可以将授权凭证中的数据标识信息对应的数据类型与上述列表中每个第二设备支持的数据类型进行对比，从而确定支持该数据类型的第二设备。
若与第一设备关联的至少一个第二设备中任意一个第二设备支持该业务类型和/或数据类型，则第一设备才启动对第一网元的授权凭证的验证过程，进而基于第一数字签名对第一网元的授权凭证进行验证。若与第一设备关联的至少一个第二设备均不支持该业务类型和/或数据类型，则第一设备忽略该授权凭证，不对该授权凭证进行验证处理。如此，可以保证第一网元接收到的数据的业务类型是符合其需求的业务类型，和/或第一网元接收到的数据的数据类型是符合其需求的数据类型，如此，提高数据授权的效率。
可选地，参考图4所示的流程示意图，本申请实施例提供的安全实现方法中，步骤220中第一设备确定第一网元具有接收至少一个第二设备发送的数据的权限之后，还可以包括以下步骤：
步骤250、第一设备接收第一网元发送的第一指示信息；该第一指示信息用于指示至少一个第二设备中需要向第一网元发送数据的第二设备；
步骤260、第一设备向第一指示信息所指示的第二设备发送第一请求信息；第一请求信息用于请求第一指示信息所指示的第二设备的数据。
本申请实施例中，在第一设备确定第一网元具有获取数据的权限之后，第一网元通过第一指示信息告知第一设备需要哪些第二设备向其发送数据。进而，第一设备可以向第一指示信息所指示的第二设备发送第一请求信息，以请求这些第二设备的数据。
需要说明的是，第一设备关联的至少一个第二设备中包括第一指示信息所指示的第二设备。
可选地，第一指示信息中可以包括需要向第一网元传输数据的第二设备的标识信息。这样，第一设备可以向第一指示信息中携带的标识信息所对应的第二设备发送第一请求信息。
可选地，第一设备信息所指示的第二设备接收到第一请求信息后，可以直接向第一网元发送自己的数据，也可以通过第一设备向第一网元转发自己的数据。本申请实施例对此不做限制。
可选地，参考图4所示，本申请实施例的安全实现方法中步骤260之后，还可以包括以下步骤：
步骤270、第一设备接收第一指示信息所指示的第二设备发送的数据；
步骤280、第一设备向第一网元发送所述数据。
本申请实施例中，第一设备向第一指示信息所指示的第二设备发起数据请求之后，第一设备还可以作为中继设备，将这些第二设备反馈的数据转发给第一网元。如此，实现数据的精准传输，保证数据传输的效率。
可选地，当授权凭证中包括业务标识信息和/或数据标识信息时，上述步骤260第一设备向第一指示信息所指示的第二设备发送第一请求信息，还可以通过以下方式实现：
第一设备向第一指示信息所指示的第二设备中，支持业务标识信息指示的业务类型和/或数据标识信息指示的数据类型的第二设备发送第一请求信息。
也就是说，第一设备在接收到第一指示信息之后，可以仅向第一指示信息所指示的第二设备中，支持上述业务标识信息对应的业务类型和/或支持上述数据标识信息对应的数据类型的第二终端发送第一请求信息。如此，可以保证第二设备发送的数据的业务类型与第一网元所需的业务类型匹配，提高传输效率。
可选地，在一些实施例中，步骤260中第一设备向第一指示信息所指示的第二设备发送第一请求信息之前，还可以与这些第二设备进行互相认证，以确保对方均为受信任的设备。在第一设备与第二设备相互认证通过后，第一设备才继续执行上述步骤260和步骤270，以实现与第二设备之间的物理层安全的数据传输。如此，避免第三方攻击者窃取和篡改数据。
本申请实施例中，第一设备可以与第二设备之间进行简单的设备认证过程，例如，第一设备与第二设备之间可以基于第二设备的初始秘钥K进行认证。其中，初始秘钥K可以是对称秘钥，每个第二设备的本地存储空间均可以存储自己的初始秘钥K。第一设备与第二设备之间也可以基于初始秘钥K进行协商，得到物理层安全秘钥s，进而第一设备与第二设备基于秘钥s进行设备认证，本 申请实施例第一设备与第二设备认证的方式不做限制。
本申请实施例中，第一设备获取第一网元的授权凭证的方式包括多种，下面详细介绍其中的两种。
方式一、
在本申请一实施例中，参考图5所示，步骤210中第一设备获取第一网元的授权凭证，可以通过以下步骤实现：
步骤2101、第一设备接收第一网元发送的第二请求信息；第二请求信息用于请求第一设备授予第一网元获取至少一个第二设备的数据的权限；第二请求信息中包括授权凭证；
步骤2102、第一设备从第二请求信息中获取授权凭证。
可以理解的是，第一网元需要获取第二设备的数据时，可以向第二设备绑定/关联的第一设备发送第二请求信息。这里，第一网元可以在第二请求信息中携带第一网元的授权凭证。这样，第一设备在接收到第二请求信息之后，可以从第二请求信息中获取第一网元的授权凭证，并基于授权凭证中的第一数字签名对该授权凭证进行验证，以确定第一网元是否具有获取第二设备数据的权限。
可选地，第一设备在接收到第二请求信息之后，可以先对发送第二请求信息的第一网元进行身份验证，确定该第一网元是否为受信任的网元，以及确定第二请求信息是否被篡改。只有在对第一网元的身份验证通过的情况下，第一设备才基于第一请求信息获取授权凭证并对该授权凭证进行验证，以此保证后续传输过程中，与第一关联的第二设备的数据不被泄露和窃取。
可选地，第一设备可以使用与第一网元之间的共享秘钥对第一网元进行身份验证，第一设备也可以使用第一网元的公钥对第一网元进行身份验证，本申请实施例对此不做限制。
可选地，第二请求信息中可以包括以下信息中的至少一项：

应理解，在第一请求信息中包括第二数字签名时，第一设备可以利用第二数字签名对第一网元进行身份验证。其中，第一设备对第一网元进行身份验证的方式包括如下内容：
第一设备利用第一网元的公钥对上述第二数字签名进行验证处理，得到第二验证信息；若第二验证信息与第二请求信息中除第二数字签名之外的其他信息一致，则第一设备确定第一网元身份验证通过。
可选地，第一设备可以维护一份公钥列表，该列表中存储了多个网元的标识信息，以及每个网元对应的公钥。第一设备接收到第一网元发送的第二请求信息后，可以从上述公钥列表中查找第一网元的标识信息对应的公钥。进而第一设备可以基于该公钥对第二数字签名进行验证，得到第二验证信息。
可选地，若第二请求信息中包括第一网元的公钥时，第一设备也可以基于第二请求信息中携带的公钥对第二数字签名进行验证，得到第二验证信息。本申请实施例对第一网元的公钥的获取方式不做限制。
应理解，在第二验证信息与第二请求信息中除第二数字签名之外的其他信息一致的情况下，第一设备确认第一网元为受信任的网元，并且第二请求信息未被篡改，第一网元进一步可以基于第二请求信息中的授权凭证进行验证，以确定第一网元是否具有获取第二设备数据的权限。
在第二验证信息与第二请求信息中除第二数字签名之外的其他信息不一致的情况下，第一设备可以认为第一网元为不受信任的网元，和/或，第一请求信息被第三方篡改。在此情况下，第一设备可以忽略该第二请求信息，不进行进一步处理。
综上所述，本申请实施例提供的安全实现方法中，第一网元可以主动向第一设备发送携带其授权凭证的第一请求信息，以请求第一设备进行验证从而授予其获取第二设备数据的权限。如此，保证第二设备的上行数据不被泄露和窃取。

可选地，授权凭证可以不存储在第一网元的本地，而是通过去中心化身份(Decentralized Identity，DID)方式，分布式存储于区块链节点中。当第一网元需要获取第二设备的数据时，可以先从区块 链节点的存储区块中获取第一网元的授权凭证。其中，参考图5所示的流程示意图，第一网元向第一设备发送第二请求信息之前，还可以执行以下步骤：
步骤2001、第一网元向区块链节点发送第四请求信息；第四请求信息用于请求第一网元的授权凭证；第四请求信息包括授权凭证在区块链节点的存储位置信息；
步骤2002、第一网元接收区块链节点发送的该第一网元的授权凭证。
也就是说，第一网元在向第一设备发送第二请求信息之前，可以根据第一网元授权凭证的存储位置信息，向区块链节点请求获取第一网元的授权凭证。在接收到区块链节点反馈的授权凭证之后，第一网元可以将获取到的授权凭证携带在第二请求信息中发送给第一设备，以使第一设备授予其获取与第一设备关联的第二设备的数据。
可选地，由于授权凭证中包括凭证发放设备的第一数字签名，基于此，第一网元接收到区块链节点发送的授权凭证之后，可以使用凭证发放设备的公钥对第一数字签名进行验证，以确定授权凭证的真实性。第一网元在对第一数字签名验证通过后，将该授权凭证携带在第一请求信息中发送给第一设备。
应理解，第一网元的授权凭证可以预先通过凭证发放设备生成。这里，凭证发放设备生成授权凭证之后，可以将授权凭证回传给第一网元，或者将授权凭证上传到区块链节点进行分布式存储。进一步地，当第一网元根据业务需要而获取数据时，可以从本地存储空间获取授权凭证，或者从区块链节点中请求授权凭证，并将获取到的授权凭证通过第一请求信息发送给第一设备。如此，提高第一设备进行数据授权的灵活性。
