Encryption Algorithm using Shuffled 2-Dimension Key

Abstract

Cryptographic algorithms are the fundamental element of security protocols and applications. They need to evolve to face the advance cyber security threats. This paper presents an encryption algorithm in which plaintext is encrypted using Shuffled 2-Dimension Key. Each time when a block is encrypted, the key is shuffled. Next time when a block is encrypted the key is different. Cipher text is more secured with shuffling 2-Dimension key as compared with same without shuffling 2-Dimension key. The results of 2-dimension array (shuffled and without shuffled) are compared with Advanced Encryption Standard (AES) algorithm. Same character is encrypted in different way as the key get changed due to shuffling.
