摘　　要：针对嵌入式系统的安全性问题,提出了基于AES-128算法的安全实现方案.基于密码算法实现准则的优先级分析,详细阐述了AES-128算法的S盒、行移位和列混合等子部件的具体设计,形成了嵌入式系统的安全实现方案.利用差分功耗分析和相关性功耗分析技术,对该实现方案进行了多次攻击测试,从而验证该方案的安全性.结果表明,在一定计算条件下,基于AES-128算法的安全实现方案具有较高的安全性,可以抵抗DPA攻击和CPA攻击.Aiming at the security problem of embedded system,a security implementation scheme based on AES-128 algorithm was proposed.According to the priority analysis of implementation criteria of cryptographic algorithm,the specific design of sub-components,such as S-boxes,row shift and column mixing of AES-128 algorithm,was elaborated,and the security implementation scheme of embedded system was formed.In addition,differential power analysis(DPA)and correlation power analysis(CPA)techniques were used for multiple attack tests on the implementation scheme,thus the security of as-proposed scheme was verified.The results show that the security implementation scheme based on AES-128 algorithm has high security level and can resist DPA and CPA attacks under certain computing conditions.
