Towards generating secure keys for braid cryptography
Abstract. Braid cryptosystem was proposed in CRYPTO 2000 as an alternate public-key cryptosystem. The security of this system is based upon the conjugacy problem in braid groups. S...

Combinatorial Group Theory and Public Key Cryptography
Abstract. After some excitement generated by recently suggested public key exchange protocols due to Anshel-Anshel-Goldfeld and Ko-Lee et al., it is a prevalent opinion now that th...

New Public-Key Cryptosystem Using Braid Groups
Abstract. The braid groups are infinite non-commutative groups naturally arising from geometric braids. The aim of this article is twofold. One is to show that the braid groups ca...

Cryptanalysis of the Public-Key Encryption Based on Braid Groups
At CRYPTO 2000, a new public-key encryption based on braid groups was introduced. This paper demonstrates how to solve its underlying problem using the Burau representation. By thi...

Pseudorandomness from Braid Groups
Recently the braid groups were introduced as a new source for cryptography. The group operations are performed efficiently and the features are quite different from those of other...
