【摘要】 作者综合利用超递增序列、杠杆函数和HASH函数的特性提出了能有效地抵御"极小点"攻击和"LOB-L3归约基"攻击的REESSE2公开密钥密码体制,详细描述了该体制的数学基础、密钥生成算法、加密算法和解密算法。文章对REESSE2体制的安全性和优越性做了分析,并归纳了提高公钥密码体制安全性的两条途径。更多还原

【Abstract】 On the basis of the super increasing sequence ,lever function and HASH function ,the authors put forward the REESSE2 public key cryptosystem which can defend efficiently attacks by the extreme small dot and LOB-L~3 reduced base,expound the math foundation and three algorithms for generating-key,encryption and decryption of the crytosystem,analyze algorithmic security and advantage,and induce the two approaches to enhancing securities of public key crytosystems.更多还原
