摘　　要：可信计算是信息安全领域研究的热点,研究可信平台模块的安全性具有重要意义。可信平台模块传统RSA加密算法缺少物理保护,具有受到侧信道攻击的风险。根据抵抗侧信道攻击的传统RSA算法,提出了一种改进方法,将RSA添加伪随机数操作方案改进为在遇到0 b时通过0,1随机数判断是否执行伪随机操作,减少了模乘运算量。研究表明,在保证安全性的前提下,改进的RSA算法可提高模块计算效率。The trusted computing is a research hotspot in the field of information security, and the study of the trusted plat- form module （TPM） security has the great significance. The traditional RSA encryption algorithm of TPM lacks of physical pro- tection, and has the risk of side-channel attacks. According to the traditional RSA algorithm to resist the side-channel attacks, an improved method is put forward. The scheme of adding pseudo-random number operation into RSA is improved to determine whether executing pseudo-random operation with 0 and 1 random numbers while encountering a 0 b, so as to reduce the modu- lar multiply operation. The research shows that the improved RSA algorithm can improve the module calculation efficiency while guaranteeing the security.
