Analysis and Implementation of Key Exchange Protocol Based on Braid Groups

Some particular word problems and conjugacy problems in braid group are unsolvable. Herein this characteristic can make use of the braid group to construct the algorithm in order to achieve data encryption in electronic commerce. Key exchange protocol enables two or more people get a key through a protocol that can be used in further data encryption. In the real world of cryptogram the key exchange plays a very important role. The implementation of the Anshel-Anshel-Goldfeld key exchange protocol and its security are emphasized here. Since the key exchange protocol can ensure the safety of the delivery between the sender and the receiver in data encryption, it will open up a vast range of prospects in the cryptography field.
