Signature authentication

Another method of IAM authentication is signature. This method uses AKSK for API signature. The specific process is that the user uses the interface information of SK and API to generate a signature string, and this signature string contains the information of AK. After receiving the request, Baidu AI Cloud verifies the signature string accordingly. The verification method is to replay the user signature process, and then determine whether the signature string is valid. It can be understood as a symmetric encryption method. By default, the authentication for accessing Baidu AI Cloud requires a signature authentication method.
