Problems solved by technology

It is not possible to implement multiple system environments across multiple products
"Single sign-on" technology can't integrate various original application systems of enterprises and institutions
In addition, the "single sign-on" technology only solves the login problem of the application system, and cannot solve the problem of encryption and decryption of files in the application system.

Embodiment Construction

[0016] As shown in Figure 1, smart card issuing subsystem 2, smart card 3, smart card account subsystem 4, smart card password subsystem 5, smart card encryption and decryption subsystem 6, smart card signature verification subsystem 7, smart card management subsystem 8, smart card issuing subsystem System 2 customizes the smart card 3 according to the user's information and needs, and writes the user's identity information, login account number and encryption and decryption key information into the smart card 3. When the user needs to log in to the operating system or application system, the smart card 3 and the smart card account number The system 4 is connected. After the user enters the correct user name and password to the smart card 3, if the user passes the identity authentication of the smart card 3, the smart card 3 outputs the account information corresponding to the user to the smart card account subsystem 4, and the smart card account subsystem 4 checks the user acco...

Abstract

A safety All-in-one-card system realized by intelligent card includes intelligent card-issue sub-system, intelligent card, the card sub-systems of account number, cipher, cipher / decipher, sign verification and management, capable of integrating safety appliances of multiple appliances system including identification certification, authrization and cipher / decipher. With one intelligent card, a user use all predesigned appliance systems bringing with him great conveience under the condition of securing safety of the appliance system especially suitable for enterprises having meltiple IT systems.

Description

technical field [0001] The invention relates to a one-card system, in particular to a safe one-card system realized by a smart card, and belongs to the technical field of information security. Background technique [0002] With the development of network technology, the degree of information construction of enterprises and institutions has been continuously improved, and there are more and more application systems in enterprises. Most of these application systems are implemented based on the network, so they also face the problem of information security. The "Design of Single Sign-On System Based on Public Key Infrastructure" (author Li Xiaoping) published in the Journal of Beijing Institute of Technology in April 2002 discloses a system using traditional security strategies, and each application system needs to maintain its own security strategy , including organizational structure definition, security role definition, user authentication, resource access control, etc. Si...
