一种基于可信计算平台的数字签名方案

A Signature Scheme Based Trusted Computing Platform

为了提高数字签名方案的安全性,提出了一种基于可信平台的签名方案,该方案采用双私钥设计,同时,利用可信平台,以及智能卡等安全设备增加了系统的安全性.为防止消息在公共信道篡改,消息和签名将被用户与签名者的一次一密密码系统加密处理.最后,给出方案的正确性证明、安全性分析.

For improving security of the digital signature, this paper proposed a signature scheme based on trusted computing plat with two secret keys,mean while, using smarty card for enhancing the security of the system. For preventing from tampering with the information on public channel, the information and the signature would be encrypted with one-time padding system by the user and signatory. Finally, the article finished correctness confirmation and security analysis for the scheme.
