Abstract
Cryptanalysis of symmetric key cryptography encourages large key size and complex operations to achieve message confidentiality. All these techniques pose computational overhead at both the sender & receiver ends. In this paper, we propose a simple yet powerful Block Cipher Multiple Key Symmetric Encryption (BCMKSE) algorithm for achieving both confidentiality & integrity with reduced computational and message overheads. Our algorithm changes the key after encrypting/decrypting a piece of the whole message. While the key changes during the whole message encryption/decryption process without increasing network traffic or message overhead. This methodology becomes faster as it uses the simplest operations like shift, XOR, addition and comparison operations.
