ECC计时攻击研究与仿真
Research and simulation of timing attacks on ECC
摘要
Abstract
Based on the hidden Markov model (HMM) idea, a timing attack on the elliptic curve digital signature system, which adopted the “double-and-add” scalar multiplication, was proposed. Simulation experiments on the secure Koblitz curve which released by the National Institute of Standards Technology (NIST) were implemented and four secure Koblitz curves except the K-571 were attacked successfully. The experiment results show that the attack can recover almost all the key bits in a few minutes by collecting only once time data, and is easy to imple-ment at a high success rate.关键词
