研究概况

主要从事密码理论及相关数学问题研究。在密码分析领域，提出了密码哈希函数的碰撞攻击理论，即模差分比特分析法；破解了包括MD5、SHA-1在内的5个国际通用哈希函数算法；将比特分析法进一步应用于带密钥的密码算法包括消息认证码、对称加密算法、认证加密算法的分析，给出系列重要算法HMAC-MD5、MD5-MAC、Keccak-MAC等重要分析结果；给出了格最短向量求解的启发式算法二重筛法以及带Gap格的反转定理等。在密码设计领域，主持设计的哈希函数SM3为国家密码算法标准，在金融、交通、国家电网等重要经济领域广泛使用，并于2018年10月正式成为ISO/IEC国际标准。

代表性论文50余篇，3篇获欧密会、美密会最佳论文。
