Based On The Dynamic Two-way Authentication Password Identification System Design And Implementation

With the developing of computer network and information technology, but the general administration of power supply is using the traditional static password authentication methods so that it can't meet the safety certification requirements of complex network at present. So a new dynamic password two-way authentication system is presented.The actuality of status authentication technology is analysised, combined with power supply network for the administration of IPSec VPN, the design and realization of the dynamic password two-way authentication system is studied. Discussed in detail IPSec VPN security mechanism design and identity the design stage.The security policy, security association, security policy database, security association database and a processing method of VPN server impact on data stream of input and output is designed first in the paper, then a dynamic password two-way authentication system based on challenge / response mechanism between client and server is developed. The operating environment and parts of realization interface is introduced at last.The number of entry and random data is introduced as the variable factor of authentication information, the factor of enrollment time is saved in UEBKEY only. the encrypted information of request, challenge and response is transmitted in the network of the new system, and that improves the security of the statusauthentication system.Dynamic password authentication system involves many, this article only someof these techniques are discussed and design, will be configured in the network, digital certificates. traffic control, and so on to do further study.
