Abstract

Cryptography is the art of achieving security by encoding messages to make them non-readable. There are two basic types of cryptography: Symmetric and Asymmetric cryptography. Symmetric Key algorithms are the quickest and most commonly used type of encryption. Here, a single key is used for both encryption and decryption. There are few well-known Symmetric Key algorithms: DES, RC2, RC4, AES, etc. more amount of information are so much private, but some are less private due to this the attacker or the hackers are taking messages. DES is now considered to be insecure for many applications because the 56-bit key size being too small is possible to brute-force infinite time on a modern processor. The AES algorithm was believed to provide more security than the DES. The AES algorithm was designed to have resistance against all known attacks, speed and code compactness on a wide range of platforms and design simplicity. A new scheme of Symmetric Key algorithm DES and AES is proposed with 1024 bit key. This technique provides more security and increases the efficiency with different key length settings. Data Encryption Standard (DES) and Advanced Encryption Standard (AES) is implemented using NS2 software to make a comparison by parameters like speed, block size, and key size.
