It is common now a day to communicate through messages. The sending and receiving message with in a network is not more secure as the people data can be accessed by everyone within that network. In order to provide security to the data most commonly the authors are using the RSA algorithm, but there are as many as drawbacks as the advantages for the RSA algorithm. For extending the security of messages they are now using the "Message-Digest", "DSA" and PRNG (Pseudo code Random Generator) algorithms. The message Security is designed to provide security by combining the concept of both the Digital Signature and Asymmetric key (Public key) Cryptography. Here the Public key is send instead of Private Key.
