In present days electronic communication is a fundamental method of exchanging information. Secure communication is a major concern by which people can share information with varying degrees of certainty that third parties cannot capture the information that is transmitted over network. With the introduction of internet and distributed systems security issues are more challenging and complex. Hence information security is an important consideration in these days. Cryptography and information security is helping to develop more number of practical approaches to enforce security for networks. In this paper the proposed algorithm which uses basic encryption techniques like substitution, transposition, bitwise logical operations along with pairing function to encrypt the data. The algorithm itself generates the key from plain text and hides within plaintext.
