CPK credibility authorization system

Abstract

This invention discloses a CPK trustable certification system with a chip including special COS, CPK algorithm, ID certificates, signature protocol, a cryptographic key exchange protocol, a ciphering algorithm and HASH function and divided into intelligent card, USB Key, Flash card and cell phone SIM card. One chip can bear the functions of a cipher machine, signature verification, cryptographic key storage and management.

Description

technical field [0001] The invention relates to information security technology, and in particular designs a CPK credible authentication system under the computer and network environment. Background technique [0002] With the development of the Internet, the requirements for computer and network security are getting higher and higher, and corresponding encryption algorithms and technologies are also developing vigorously. The current encryption technology can be divided into two categories, namely symmetric key technology and asymmetric key technology. Among them, the asymmetric key technology has been widely used because it can avoid the need of transmitting the decryption key, that is, the private key through the network. [0003] The most well-known technology of the asymmetric key to those skilled in the art is PKI (Public Key Infrastructure). The operation of PKI relies on two major components: a hierarchical CA organization (CertificationAuthority) and a huge certif...
