3.1.1 Advance Encryption Standard (AES)

The AES module provides hardware-accelerated data encryption and decryption operations based on a binary key. The AES is a symmetric cipher module that supports a 128-, 192-, or 256-bit key in hardware for encryption and decryption. The AES module is based on a symmetric algorithm, which means that the encryption and decryption keys are identical. To encrypt data means to convert it from plain text to an unintelligible form called cipher text. Decrypting cipher text converts previously encrypted data to its original plain text form. The main features of the AES accelerator are:

AES encrypt and decrypt operations are supported by:

  • Galois/Counter mode (GCM), with basic GHASH operation
  • Counter mode with CBC-MAC (CCM)
  • XTS mode

The following feedback operating modes are available:

  • Electronic code book mode (ECB)
  • Cipher block chaining mode (CBC)
  • Counter mode (CTR)
  • Cipher feedback mode (CFB), 128-bit
  • F8 mode
  • Key sizes: 128, 192, and 256 bits
  • Support for CBC_MAC and Fedora 9 (F9) authentication modes
  • Basic GHASH operation (when selecting no encryption)
  • Key scheduling in hardware
  • Support for µDMA transfers
  • Fully synchronous design
