| 摘 要： | 针对添加伪点加法在抵抗简单功耗分析攻击的同时效率损失过大的问题,为更好兼顾效率与安全,提出一种新的标量乘快速实现算法——随机伪操作法,通过以单片机为核心运算控制芯片的功耗分析平台进行实测分析验证,随机伪操作法不但能够很好抵抗简单功耗分析攻击,而且相对于添加伪点加法运算效率提高30%-50%。

| Abstract: | The pseudo-point additions method acquires resisting Simple Power Analysis Attacking(SPA) capability at cost of greatly power losing.The novel Random-Pseudo Operation algorithm of fast scalar multiplication method was proposed to improve its security with better efficiency.A power analyzing platform with the MCU being as kernel control chip was designed for validation purpose.Results show the novel algorithm not only could be well resisting against SPA attacks, but also increase efficiency by about 30-50 pe... |
