Overview
The Advanced Encryption Standard (AES) and Data Encryption Standard (DES) are two commonly used standards for
cryptography. These are supported through an AES peripheral module and a DES CPU instruction, and the
communication interfaces and the CPU can use these for fast, encrypted communication and secure data storage.
DES is supported by an instruction in the AVR CPU. The 8-byte key and 8-byte data blocks must be loaded into the
register file, and then the DES instruction 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 encryption/decryption is started. It takes 375 peripheral
clock cycles before the encryption/decryption is done. The encrypted/encrypted data can then be read out, and an
optional interrupt can be generated. The AES crypto module also has DMA support with transfer triggers when
encryption/decryption is done and optional auto-start of encryption/decryption when the state memory is fully loaded.
