摘要
TPM具有隐私保护能力和存储保护能力。使用盲签名可以实现被签名信息的匿名性,群签名可以实现签名者的匿名性。两者相结合可以实现双方的匿名性,从而实现交互的安全性。采用椭圆曲线算法ECC加密,可以提高系统运行效率。提出了一种基于TPM和群盲签名的电子现金方案,其主要目的是在保证系统安全性的前提下,提高系统的运行效率。并对方案进行了性能分析。
TPM has privacy and storage protections. The blind signature can achieve anonymity of information that is signed,group signature can achieve anonymity of the signer. Combination of the two sides can achieve the interactive safety. ECC elliptic curve algorithm can improve system efficiency. This paper proposed electronic cash scheme based on TPM and group blind signature,its main purpose was to improve efficiency of the system under the premise of ensuring the security of the system. And then analyzed the performance of the program.
