【摘要】：隨著網(wǎng)絡和通信技術的發(fā)展,多服務器的身份認證問題成為近幾年研究的重點。針對Chuang等人提出的基于生物特征的多服務器密鑰認證方案存在的安全性不足等問題,Wang等人進行了改進,但是仍未解決不同服務器密鑰相同造成的惡意攻擊和偽造攻擊等問題。因此,提出了一種更安全的基于智能卡的多服務器身份認證方案。該方案在服務器注冊階段,將高熵秘密數(shù)與服務器的ID進行計算再重新分配給服務器,使得不同的服務器具有不同的密鑰。最后通過五個方案功能和性能比較分析,得出改進方案比前三種方案時間上分別縮短了16.67%、20%、28.57%,且能有效阻止惡意服務器攻擊、偽造攻擊、重放攻擊和中間人攻擊等多種攻擊,安全性得到了提高,滿足實際網(wǎng)絡的高可靠性需求。
[Abstract]:With the development of network and communication technology, multi-server identity authentication has become the focus of research in recent years. In order to improve the security of Chuang et al.'s biometric-based multi-server key authentication scheme, Wang et al has improved it, but it has not solved the problem of malicious attack and forgery attack caused by the same key of different servers. Therefore, a more secure multi-server authentication scheme based on smart card is proposed. In the stage of server registration, the high entropy secret number and the ID of the server are calculated and redistributed to the server, which makes different servers have different keys. Finally, by comparing and analyzing the function and performance of the five schemes, it is concluded that the improved scheme can shorten 16.67 times compared with the previous three schemes, and can effectively prevent the malicious server attack, forgery attack, replay attack and man-in-the-middle attack, and so on, and can effectively prevent the attack, such as malicious server attack, forgery attack, replay attack and man-in-the-middle attack, etc. The security is improved to meet the high reliability requirements of the actual network.
