基于USB Key的安全增强密钥生成方案
Security-enhanced key generation scheme based on USB Key
摘要
Abstract
Aiming at the shortage of key storage security in embedded system,a Security-Enhanced Key(SEK)genera-tion scheme is proposed.By using the unique hardware eigenvalue of the Embedded System(ES)and the random number generated by the USB Key(UK),the respective key seeds are generated without changing the architecture of the existing ES.Then the key seeds are used to generate the SEK by both sides with Diffie-Hellman Key Exchange(DHKE).Generated when needed only and destroyed immediately after used,SEK does not need to store in embedded device,but improves the security of the key fundamentally and solves the ES key leakage security issues to a certain degree.The implementa-tion of the prototype and the security evaluation show that the scheme can defense a variety of attacks on SEK, the key security is obviously improved after adding the scheme,and the additional overhead will not have a significant nega-tive impact on the system performance.关键词
