The feature that makes the braid groups useful to cryptography includes the followings: (i) The word problem is solved via a fast algorithm which computes the canonical form which can be efficiently manipulated by computers. (ii) Th

Cannabis Laboratory Fundamentalseme is provably secure in the random oracle model, assuming that inverting RSA is hard. In this paper we exhibit a slightly di.erent proof which provides a tighter security reduction. This in turn improves the e.ciency of the scheme since smaller RSA moduli can be used for the same level of security

Due to these weaknesses one should impose at least certain restrictions on the allowed parameter values when using the SL.(.) hashing scheme for cryptographic purposes.
