Analytical Study of AES and Proposed Variant with Enhance Block Length and Key Length

Sayed Tathir Abbas | Ravindera Kumar

Abstract: Encryption and decryption are both methods used to ensure the secure passing of messages and other sensitive documents and information. The encryption process plays a major factor in our technology advanced lives. Encryption basically means to convert the message into code or scrambled form. Advanced Encryption Standard (AES) is a specification for the encryption of electronic data. It has been adopted by the U. S. government and is now used worldwide. AES is a symmetric-key algorithm, meaning the same key is used for both encrypting and decrypting the data. This paper defines the method to enhance the block and key length of the conventional AES.

Keywords: Plaintext, Cipher text, key length, block length
