摘要: 辫群是构造对抗量子公钥密码系统的新工具.已知的基于辫群共轭问题的公钥密码系统都受到不同程度的攻击.提出了一个基于辫群求根问题的公钥密码算法, 随后对算法的正确性、安全性、参数选择和效率进行分析.新的公钥密码算法可以抵抗各种已知攻击.Abstract: The braid group is a new tool for constructing quantum attack-resistant public key encryption algorithm.A public key encryption algorithm base on root finding problem over braid group is put forward, the analysis of its correctness, security, efficiency and parameter choice are subsequently presented.The new algorithm can resist current known attacks.
