摘　　要：功耗分析攻击已成为智能芯片最具威胁的攻击方法之一。针对安全和效率之间的矛盾,给出一种抗功耗分析攻击的安全高效标量乘算法。通过将标量编码成带符号阶乘展开式的形式,并采用基点掩码实现抵御功耗分析攻击,然后利用半点运算提高标量乘的运算效率。性能分析结果表明:新抗功耗分析攻击方案不仅能抵御多种功耗分析攻击,且同经典抗功耗分析攻击算法相比,新方案能够有效提高运算效率,在资源受限的各种应用系统中具有很好的推广应用价值。Power analysis attack has become the most threatening method for smart chips. In order to solve the contradiction between safety and efficiency, a secure and efficient scalar multiplication algorithm with power analysis attack resistance is proposed. The scalar is coded into signed factorial expansion forms and the point masking is used to resist power analysis attacks. Meanwhile, the operation efficiency of scalar multiplication could be improved by using point halving. The performance analysis results show that the novel algorithm could not only resist various power analysis attacks, but also improve the efficiency effectively by comparing with the traditional algorithm of resisting power analysis attack. So the novel scheme has a preferable value of application in variety of application systems of limited resource.
