Sparse approach for realizing AVK for Symmetric Key Encryption

Symmetric key cryptography has been a hot topic because of exchange of secure communication through various networks ligand Investigation of reversible XOR like function for symmetric key cryptography has been a big challenge. Moreover it is also desired that the reversible XOR function must be as efficient as traditional XOR. In the literature related to Automatic Variables Key, Fibonacci-Q matrix based key generation has also been proposed and used. This paper proposes a algorithm for cryptographic information exchange without transmitting key to end user. The proposed algorithm has been proposes new perspectives for secure communication using AVK approach for low power devices together with saving the key computation time.
