摘要: 为评估生物密钥系统在侧信道攻击下的安全性能,在分析生物密钥系统结构和特点的基础上,将用户的击键生物特征和秘密共享方案相结合,设计一个基于击键的安全生物密钥系统,并通过差分能量攻击技术测量安全生物密钥系统的功耗泄漏。仿真分析表明,攻击者借助少量的功耗泄露就可以破解生物密钥系统的信息。

Abstract: To assess the biometric cryptosystem performance in possible side-channel attacks, on the basis of analysis of the biometric cryptosystem structure and characteristics, a secure biometric cryptosystem based on the keystroke is designed by the combination of the user's keystroke biological characteristics and secret sharing scheme. Power consumption leakage of the safe biometric cryptosystem is measured with the Differential Power Attack(DPA). Simulation analysis shows the biometric cryptosystem can be extracted with bits of power leakages.

Key words: biometric cryptosystem, side-channel attack, Differential Power Attack(DPA), power consumption leakage
