ABSTRACT: The private-key structure of CPK has developed from single-layer and multi-layer to multi-block and composite structure. The scheme structure of CPK has formed as fixed, flexible or disposable types. CPK digital signature forms an identity signature protocol not only for data signature, but also for identity signature. CPK is not only suitable for the authentication requirements of open global communication network and business network, but also suitable for the authentication requirements of closed local communication network and business network. The disposable private-key structure can resist quantum exhaustion.
