A hybrid algorithm based authentication method for internet access users
A hybrid algorithm based internet access user identity authentication method is proposed.Establish an education blockchain identity authentication framework by combining intra domain and cross domain alliance chains.After setting a fixed authoritative node in the authentication architecture,combined with certificateless signature and hash function,complete the reasonable registration of institutional nodes and user nodes.Establish a security authentication mechanism based on a hybrid algorithm.First,use the SM4 algorithm(SM4 Block cipher algorithm)in the national security algorithm to generate an initial key,and use the SM2 algorithm(SM2 elliptic curve public key cryptography algorithm)to further process the key data to obtain a random key that can be used for identity authentication.Finally,under the role of an authentication server centered on cloud computing,stage authentication is performed on the identity of internet access users.The experimental results show that when the number of concurrent users is 300,the proposed method only has a response time of 2.85 seconds for internet access user authentication,meeting the real-time requirements.
