发布时间：2018-10-23 07:29
【摘要】：安全芯片有资源受限的问题,这致使椭圆曲线密码算法抵抗功耗攻击的方案在效率和安全两方面产生了矛盾。首先利用带符号的整数拆分形式对标量进行编码,并采用预计算和标量分割技术把标量乘运算变换成一组椭圆曲线上的点的点加运算,进而利用基点掩码实现椭圆曲线密码的抗功耗攻击。算法安全性及性能分析结果表明,基于整数拆分的抗功耗攻击方案的运算效率与传统的抗功耗攻击方法相比明显提高,可以很好地满足安全芯片等资源受限的应用系统。
[Abstract]:The security chip has the problem of limited resources, which leads to the contradiction between the efficiency and the security of the elliptic curve cryptosystem to resist the power attack. First, the scalar is coded in the form of signed integer splitting, and the scalar multiplication is transformed into a set of point addition operations on an elliptic curve by using precomputed and scalar segmentation techniques. Then the base-point mask is used to implement the power attack of elliptic curve cipher. The results of security and performance analysis show that the computational efficiency of the scheme based on integer splitting is significantly higher than that of the traditional anti-power attack method, and it can meet the needs of resource-constrained applications such as security chips.
