The Helion AES cores implement the 128-bit block-size NIST FIPS AES algorithm. Two main functions are available, encryption and decryption, and are offered in a single core for best area efficiency. The encryptor core accepts a 128-bit plaintext input block, and generates a corresponding 128-bit ciphertext output block using a supplied 128-, 192-, or 256-bit AES key. The decryptor core provides the reverse function, generating plaintext from supplied ciphertext, using a similar AES key as was used for encryption.

Key Features

• Implements AES (Rijndael) to latest NIST FIPS PUB 197.
• Full dynamic support for all AES key sizes (128, 192 and 256-bits).
• Designed especially for low data throughput/ultra-low area applications.
• Full support available for all Block Cipher Modes.
• Available under the terms of the SignOnce IP License
