下面结合场景实施例对本发明进行描述。
本实施例给出了客户端自签名数字证书的产生和使用方法。客户端自行产生和配置数字证书，业务平台(或称为服务端)将用户和/或设备与数字证书进行绑定，从而可通过数字证书实现对客户端用户和/或设备的认证。
实施例一
该实施例为客户端自签名数字证书产生、发送和绑定流程，包括：
步骤一：客户端软件在设备中安装时，客户端产生公私钥对，并产生自签名数字证书。
可选的，为了实现客户端与设备的绑定，该自签名数字证书中还可以包括设备信息和/或客户端信息；其中，设备信息如设备序列号，或者设备的指纹信息，客户端信息如版本号。
步骤二：客户端将该自签名数字证书发送到区块链数字证书系统中。
其中，区块链数字证书系统是已有技术，区块链数字证书系统中的节点对自签名数字证书进行验证，通过共识后将该自签名数字证书记录到区块链数字证书系统中，基于区块链的数字证书系统如图5所示，其中，本实施例中的客户端对应于所述证书用户/设备，本实施例中的业务平台对应于所述验证方，具体不再详述。
步骤三：用户在首次成功登录上述已安装的客户端时，客户端将用户信息和证书信息(可以是完整证书，也可以是证书ID，证书的散列值，或其他能够标识出该数字证书的信息)发送到业务平台。
步骤四：业务平台记录用户信息和证书信息的对应关系。
这里，由于自签名数字证书是在客户端安装时产生，因此不具有用户信息，如果多个用户使用同一设备的同一客户端，那么将导致多个用户对 应于同一个数字证书，在客户端使用证书登录时，仅使用证书信息无法区分用户，需要辅助使用其他信息才能区分用户，如本地生物校验或口令校验等方式；也可以采用如下实施例二解决上述用户认证问题。
实施例二
本实施例为客户端自签名数字证书产生、发送和绑定流程，包括：
步骤一：客户端软件安装到设备中；
步骤二：用户在首次成功登录上述已安装的客户端时，客户端产生公私钥对，并产生自签名数字证书。
这里，为了实现证书与用户和/或设备和/或客户端的绑定，该自签名数字证书中还可以包括用户信息和/或设备信息和/或客户端信息；其中用户信息如用户ID；所述设备信息如设备序列号，或者设备的指纹信息；所述客户端信息如版本号。
步骤三：客户端将该自签名数字证书发送到区块链数字证书系统中。
其中区块链数字证书系统是已有技术，系统中的节点对自签名数字证书进行验证，通过共识后将该自签名数字证书记录到区块链系统中。
步骤四：客户端将用户信息和证书信息(可以是完整证书，也可以是证书ID，证书的散列值，或其他能够标识出该数字证书的信息)发送到业务平台。
步骤五：业务平台记录用户信息和证书信息的对应关系。
实施例三
该实施例为客户端自动登录过程，当上述客户端证书产生、发送和绑定流程执行完毕之后，业务平台已经记录用户信息与证书信息的对应关系。该流程包括：
步骤一：用户启动该客户端程序时，客户端向业务平台发送登录请求；
步骤二：业务平台收到登录请求后，向客户端发送随机数；
步骤三：客户端调用与当前客户端用户对应的私钥对收到的随机数进行签名，并将当前客户端用户的证书信息以及签名结果发送给业务平台，其中证书信息可以是完整的数字证书，也可以是证书的ID、散列值等可以标识证书的其他信息；
可选的，调用私钥时，还可以采用生物认证或口令认证等方式对私钥加以保护，确定只有认证通过时才可调用私钥进行签名。
步骤四：业务平台利用区块链数字证书系统验证数字证书，验证内容包括证书未被撤销，证书处于有效期等；如果步骤三中未包含完整的数字证书，那么业务平台还可以利用区块链数字证书系统查询到完整的数字证书。
步骤五：业务平台验证客户端的数字签名，若签名正确，则根据数字证书查找到相应的用户和/或设备和/或客户端，从而实现对用户和/或设备和/或客户端的认证。
上述步骤四、五也可参考相关技术。
本实施例客户端自行产生和配置数字证书，无需引入CA或第三方，业务平台(或称为服务端)将用户或/和设备与数字证书进行绑定，从而可通过数字证书实现对客户端用户和/或设备的认证，为用户提供个性化服务，提升用户体验；与口令认证方式相比，可避免口令存储和传输的风险，也避免了弱口令风险，提升安全性；与生物认证方式相比，对终端要求比较低，兼容性高；较传统证书方式相比，不涉及CA或第三方，减少了向第三方CA机构购买证书、或者建设和维护CA的成本。
以上所述，仅为本发明的较佳实施例而已，并非用于限定本发明的保护范围。
