Technical Problem
其主要目的是为了解决IP网中的信令控制，以及同软交换平台的通信，从而构成下一代的增值业务平台，但是目前在SIP认证过程中，采用非对称国密签名算法进行签名，而非对称国密签名算法会存在破解风险，容易导致SIP认证过程被泄露
Benefits of technology
综上所述，本申请实施例提供一种基于后量子和国密混合签名算法的SIP认证方法，应用于SIP客户端，该方法包括：向SIP服务端发送第一注册消息，第一注册消息包括：目标认证控制参数，第一注册消息用于使得SIP服务端根据目标认证控制参数生成SIP服务端对应的第一回复消息；接收SIP服务端发送的第一回复消息；根据第一回复消息，获取SIP客户端的第一混合签名证书、产生SIP客户端对应的第一随机数，并采用国密签名算法和后量子签名算法对第一随机数进行混合签名生成第一签名值；向SIP服务端发送第二注册消息，第二注册消息包括：第一随机数、第一签名值和第一混合签名证书，第二注册消息用于使得SIP服务端采用预先存储的SIP客户端的根证书，对第一混合签名证书进行验证，并根据SIP客户端的混合签名公钥对第一签名值进行验证；接收SIP服务端发送的第二回复信息，第二回复信息用于指示SIP客户端是否验证成功。本申请的方法，通过在SIP认证的流程中，融入后量子算法，使得SIP认证具备抗量子攻击的特性，使认证过程更加安全。

Abstract
The application provides a SIP authentication method based on a post-quantum and national secret hybrid signature algorithm, applied to a SIP client, and the method comprises the following steps: sending a first registration message to a SIP server, wherein the first registration message comprises a target authentication control parameter, so that the SIP server generates a first reply message according to the target authentication control parameter; receiving the first reply message; obtaining a first hybrid signature certificate of the SIP client according to the first reply message, generating a first random number, and performing hybrid signature on the first random number to generate a first signature value; sending a second registration message to the SIP server, so that the SIP server verifies the first hybrid signature certificate by using a pre-stored root certificate of the SIP client, and verifies the first signature value; and receiving second reply information indicating whether the SIP client is verified successfully. By integrating the post-quantum algorithm, the SIP authentication has the characteristics of resisting quantum attacks.
