Overview
The Advanced Encryption Standard (AES) and Data Encryption Standard (DES) are two com-
monly used encryption standards. These are supported through an AES peripheral module and
a DES CPU instruction. All communication interfaces and the CPU can optionally use AES and
DES encrypted communication and data storage.
DES is supported by a DES instruction in the AVR XMEGA CPU. The 8-byte key and 8-byte
data blocks must be loaded into the Register file, and then DES must be executed 16 times to
encrypt/decrypt the data block.
The AES Crypto Module encrypts and decrypts 128-bit data blocks with the use of a 128-bit key.
The key and data must be loaded into the key and state memory in the module before encryp-
tion/decryption is started. It takes 375 peripheral clock cycles before the encryption/decryption is
done and decrypted/encrypted data can be read out, and an optional interrupt can be generated.
The AES Crypto Module also has DMA support with transfer triggers when encryption/decryp-
tion is done and optional auto-start of encryption/decryption when the state memory is fully
loaded.
