【摘要】 通过对HARN-LIN协议及两种改进方案进行详尽的安全性分析,指出了HARN-LIN协议存在安全缺陷的根本原因.提出了一种既完全根除HARN-LIN协议缺陷,又不违背HARN-LIN协议不使用单向哈希函数初衷的改进方案,并且从正确性、安全性和协议效率等方面对本改进方案进行了详细的论证.结果表明,本改进方案可以保障通信双方安全地建立并共享多个通信密钥.更多还原

【Abstract】 This paper analysed the HARNLIN protocol and the two modifications, and pointed out the essential cause of the bug for security. Also, this paper proposed one modification that not only eradicates the bug of the original protocol, but also obeys the original intention not to use oneway function. At last, it discussed the proposed modification in validity, security and efficiency. The results indicate that the proposed modification can guarantee the creation and sharing of multiple secret keys between communication peers.更多还原
