Embodiment Construction

[0042] Figure 1 depicts a simplified diagram of a digital certificate system including a certificate authority system, a registration authority system, a certificate management system, a key management system, an information release and interface system, and a client access program. The client access program runs in the client system, and the certificate authority system, registration authority system, certificate management system, key management system, information release and interface system together constitute the server of the digital certificate system. The certificate management system, key management system, information release and interface system can be part of the registration authority system, or exist independently of the registration authority system.

[0043] The certificate authority system is responsible for creating and issuing end-entity certificates in X509 format, which represent the identity of the subject end-entity as the name of the subject being regis...

Abstract

Applying to no / weak local storage system client digital certificates system belong to a digital certificate system technology. Its features are: based on public key infrastructure architecture, containing certificates body system, a registered body system, certificate management systems, key management system, information dissemination and interface systems and procedures for client visit one or more of these components, adopted random number, salt and several rounds of iteration, etc to guarantee the security of the system and conducted by the client decryption key generation and processing operation means to achieve the system's scalability. The system without the help of key external storage devices solved the network computer systems deployed digital certificate system in the terminal when the entity's private key data storage needs of the local computer network and storage characteristics of contradictions. Thus in ensuring security and scalability simultaneity, the digital certificate system implementation complexity and costs are lower.

Description

technical field [0001] The invention relates to a digital certificate system, in particular to the technical field of a digital certificate system suitable for a client system with no / weak local storage capability. Background technique [0002] Since ENIAC, the originator of modern electronic computers, came out at the University of Pennsylvania in 1946, computer technology and computing forms themselves have undergone tremendous changes. After experiencing several waves of computer development, the current computer is developing in a comprehensive direction, and there have been mainframe (Mainframe) mode, personal computer (Personal Computer) mode, client / server (Client / Server) mode, network computer ( Network Computer) mode and other computing modes coexist. Among these numerous computing modes, there is a class of client systems with no / weak local storage capabilities, among which thin client terminals, diskless workstation terminals, network computer terminals, and tran...
