English abstract
Digital communication is the prominent technique used by various organizations for information exchange. It replaces the traditional methods with the help of internet and its related technologies. There is a chance to retrieve the contents of the transmitted message from the unsecure communication medium. The biggest challenge is to deploy a suitable mechanism for secure communication. Cryptography plays a dominant role in the information security domain. This paper proposes a modified Polybius square based approach for efficient key generation. New key is obtained from the original key by performing three different operations on modified Polybius square namely Square ring rotation, Square reversal and Transpose. From the security analysis it can be inferred that the proposed approach generates an efficient key.
