5.2.2 In Depth

The Advanced Encryption Standard (AES) hardware accelerator found on TI C2000 products is capable of operating in the most common modes for encryption/decryption, authentication, and authenticated encryption with associated data (AEAD). It supports the key sizes of 128 bits, 192 bits, and 256 bits, with a throughput of up to 4 bits/cycle, depending on the operation and key size. Utilizing a DMA, the engine requires very little CPU intervention, allowing you to manage the security of your communications while performing other vital tasks with the CPU.

GUID-8B6DF5E1-13B8-46ED-914E-FDBDC993F09F-low.gifFigure 5-3 AES Block Diagram

For message confidentiality alone, the following encryption/decryption modes are supported:

  • Electronic Code Book (ECB)
  • Cipher Block Chaining (CBC)
  • Counter (CTR) or Integer Counter (ICM)
  • Cipher Feedback (CFB)
  • Cipher Text Stealing (XTS)
  • F8

For message integrity alone, the following authentication modes are supported:

  • Cipher Block Chaining Message Authentication Code (CBC_MAC)
  • F9

If both confidentiality and integrity of messages are required, the following authenticated encryption with associated data (AEAD) modes are supported:

  • Galois Counter Mode (GCM)
  • Counter Mode with CBC-MAC (CCM)
