摘要:

针对椭圆曲线非相邻形式(NAF)标量乘法不能很好地抵抗简单功耗分析攻击(SPA)的问题,对NAF标量乘的实现算法以及对NAF标量乘的SPA攻击原理进行了分析,提出一种新的标量乘实现算法——平衡能量NAF标量乘法。通过对智能卡功耗分析平台的实测波形进行分析验证,平衡能量NAF标量乘法不仅继承了NAF标量乘法运算效率高的优点,而且能够很好地抵抗SPA攻击,提高密码芯片的安全性。

Abstract:

Against the problem that non-adjacent form(NAF)scalar multiplication on Elliptic curve cryptography(ECC) were not well resist the simple power attack(SPA),the implementation of NAF scalar multiplication and the mechanism of SPA attack were analyzed.Then a new algorithm,named equal power NAF scalar multiplication was presented.It was verified that equal power NAF scalar multiplication was efficient countermeasure against SPA attack by experimental analysis on power traces of the smartcard collected from the power analysis platform.
