The incremental growth of computer networks by new users joining the network results in a confidentiality problem with the transmission of data. To solve this problem, symmetric/asymmetric key cryptography is mostly used. However, this cipher suffers from the problem of secret key maintenance and distribution across the internet which is unsecure channel. To get rid of this problem, different key exchange schemes have been developed and classified as a key redistribution scheme, key distribution scheme and key agreement scheme.
