Description
Advanced Encryption Standard (AES) is a United States government standard algorithm for encrypting and decrypting data.
The Adaptive Digital Technologies AES Encryption and Decryption allow a Texas Instruments DSP or Texas Instruments MSP430 application to Encrypt and Decrypt character data according to the FIPs – 197 AES Standard.
The Advanced Encryption Standard specifies a FIPS-approved cryptographic algorithm that can be used to protect electronic data. The AES algorithm is a symmetric block cipher that can encrypt (encipher) and decrypt (decipher) information. Encryption converts data to an unintelligible form called ciphertext; decrypting the ciphertext converts the data back into its original form, called plaintext.
Each AES cipher has a 128-bit block size, with key sizes of 128, 192 and 256 bits, respectively. The AES ciphers have been analyzed extensively and are now used worldwide. AES is one of the most popular algorithms used in symmetric key cryptography.
