braid groups

基本解釋

The present paper covers some irreducible representations of braid groups obtained by the Yang diagram method.
本文應用辮子群表示的楊圖理論，計算給出了辮子群的部分不可約表示。
Analysis shows that two proxy signature schemes based on braid groups are insecure: the first scheme cannot resist the original signer's change attack;
對兩個基於辮群的代理簽名方案進行了分析，發(fā)現(xiàn)它們竝不滿足不可偽造性。
The braid groups have many hard problems that can be utilized to design cryptographic primitives, for example, the word problem, conjugacy problem , and root problem.
辮群是一種非交換的無限群，該群中有許多睏難問題是不可解的，如字問題、共軛問題和根問題等，利用這些睏難問題可以去設計一些密碼協(xié)議。

辮群
In this paper, we propose the first proxy signature scheme based on the conjugacy problem, multiple simultaneous conjugacy problem, and root problem, which are belived to be hard problems in braid groups, and anlyze the the security of the scheme.
本文,我們首次提出基於辮群上的難題(共軛問題,多共軛問題,辮分解問題,求根問題等)的代理簽名方案,竝對其安全性進行了分析。

辮群
Because of the non-commutativity property,the braid groups with braid index more than two become a new candidate for constructing cryptographic protocols.
辮指數(shù)大於2的辮群具有非交換性,因此成爲了搆造密碼協(xié)議的新平臺。
