Vol. 2, Issue 3, March 2014 AES Algorithm Using 512 Bit The new algorithm AES 512 consists of input block of 512 bit and key 512 bit. Due to this provision it becomes more resistant to linear and differential encrypt analysis providing high security and throughput by consuming less memory and processor. The result show that the tremendous increase in the throughput to 230% than AES 128 bit algorithm. CipherShield FIPS 140-2 Level 2 512-bit AES USB 3.0/eSATA

Online Tool for AES Encryption and Decryption Advanced Encryption Standard(AES) is a symmetric encryption algorithm. AES is the industry standard as of now as it allows 128 bit, 192 bit and 256 bit encryption.Symmetric encryption is very fast as compared to asymmetric encryption and are used in systems such as database system.
