[1,2,10,11] show that such relations exist for several well known constructions of stream ciphers immune to all previously known attacks. In particular, they allow to break two ciphers using LFSRs and completely “well

We show the proposed method solves the DHCP for the image of braids under the Lawrence-Krammer representation and the solutions play the equivalent role of the original key for the DHCP of braids. Given a braid index . and a canonical length ., the complexity is

We demonstrate attacks which use decryption failures to recover the private key. Such attacks work for all standard parameter sets, and one
