It introduction braid group application in Cryptosystem.
介绍了辫群及其在密码学中的应用。
Finally, some newly presented public key systems, such as public key cryptosystem based on braid group and quantum cryptosystem, are briefly introduced.
最后我们简单的介绍了最近所提出的一些公钥密码体制如基于辫群的密码体制，量子公钥密码体制等。
The braid group is infinite non-commutative group, and it has many hard problems that can be utilized to design cryptographic primitives, such as the word problem, conjugacy problem and root problem.
辫群是一种非交换的无限群，该群中有许多困难问题是不可解的，如字问题、共轭问题和根问题等，利用这些困难问题可以去设计一些密码协议。
It seems that braid group is a kind of considerable public key cryptography platform, but current key agreement protocols, such as AAG, AAFG and BDH, all have different degrees of security weaknesses.
辫子群是一种新兴的适用于量子计算机时代的公钥密码平台，但是目前基于辫子群的密钥协商协议AAG、AAFG和BDH等都有不同程度的安全弱点。
