Identity method based on public key certificate

Abstract

The invention relates to an identity verification method based on shared key certificates. It is a method of varying identity based on discrete logarithms with collision resist different functions and shared certificate. It is safe with a fast calculation speed, which has been proved. It can be used in identity verification so as to control storage, electric business, bills, certificates and the identity verification of information transmitters in communication

Description

technical field [0001] The invention relates to an identity authentication method for confidential or safe communication, in particular to an identity authentication method based on a public key certificate. Background technique [0002] Identity authentication refers to the confirmation technology of user identity, which is the first and most important line of defense of network security. Various applications and computer systems in the network need to confirm the legitimacy of a user through identity authentication, and then determine the user's personal data and specific permissions. When using a credit card in life, you need to enter a password, and you need to show your ID card when you get on the plane, etc. These are all application examples of identity authentication. The existing identity authentication methods generally include identity authentication methods based on zero-knowledge theory, identity authentication methods based on informa...

Problems solved by technology

However, for applications with limited computing resources such as smart cards, this algorithm is not ideal

Because the exchange of information with the outside is time-consuming, and the amount of storage required for each authentication makes the limited resources of the card more strained
