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. If you wanted to do this you could just do the 3DES trick but with 256 bit AES. (Triple DES - Wikipedia) Because of the meet-in-the-middle attack there would be roughly 512 bits of security, even with [math]3\cdot 256 [/math] key bits. Also it is naturally 3 times slower than 256 bit AES. AES is a variant of Rijndael, with a fixed block size of 128 bits, and a key size of 128, 192, or 256 bits. By contrast, Rijndael per se is specified with block and key sizes that may be any multiple of 32 bits, with a minimum of 128 and a maximum of 256 bits. AES operates on a 4 × 4 column-major order array of bytes, termed the state. AES provides 128 bit, 192 bit and 256 bit of secret key size for encryption. Things to remember here is if you are selecting 128 bits for encryption, then the secret key must be of 16 bits long and 24 and 32 bits for 192 and 256 bits of key size. Now you can enter the secret key accordingly. May 01, 2013 · For 128/192/256-bit AES, this formula’s correctness is confirmed. 256-bit AES has (256/32)+6 rounds or simply fourteen rounds. By applying the same equation, the number of rounds for 512-bit and 1024-bit can be determined such that 512-bit AES iteration rounds would be (512/32)+6 or 22 rounds and 1024-bit AES rounds would be 38 rounds. BUSlink CipherShield 512-bit Encrypted External Hard Drive provides first class hardware encryption to ensure integrity and confidentiality of critical data such as sensitive medical records for healthcare institutions in their effort to comply with HIPAA, classified legal information for law firms, and to protect company's financial information from theft. The new algorithm (AES-512) uses input block size and key size of 512-bits which makes it more resistant to cryptanalysis with tolerated area increase. AES-512 will be suitable for applications
