Security authentication method combining multiple algorithms

Abstract

The invention provides a security authentication method combining multiple algorithms. The method comprises the following steps: 1) an authentication party sends a random number to the authenticated party; 2) the authenticated party selects an authentication algorithm to be adopted in the present authentication from at least two pre-appointed authentication algorithms according to a pre-appointedselection algorithm, then calculates an authentication check value according to the selected authentication algorithm and a received random number, and sends the authentication check value to the authentication party; 3) the authentication party selects the authentication algorithm to be adopted in the present authentication from the at least two pre-appointed authentication algorithms according to the pre-appointed selection algorithm, then calculates the authentication check value according to the selected authentication algorithm and the random number in the step 1); and 4) the authentication party compares the locally calculated authentication check value with the received authentication check value from the authenticated party to judge the authentication result. By adoption of the security authentication method, the threat of the key being broken by violence can be effectively reduced.

AI Technical Summary

Benefits of technology

This new technology helps prevent key damage from being forced open by applying strong pressure on it or trying different methods until there are no signs of any problem beforehand. It also makes sure each piece of hardware used during an attack doesn't have its own vulnerabilities.

Problems solved by technology

Technological Problem addressed in this patented text relates how sensitive personalized electronic communication services require strong cryptographic techniques such as secure multi-factor authensis (SMA) protocols like Xiaoshuo's PINKID system. While traditional password systems only allow one user access per session, these solutions use shared secrets - they may also break down due to attacks from outside sources. There needs a more efficient method to ensure reliable encrypted identity verification without compromising any trustworthiness concerns associated with conventional digital certificatings.
