Compact AES-based architecture for symmetric encryption, hash function, and random number generation

Symmetric encryption, secure hashing, and random number generation are essential operations for many cryptographic applications. Realizations of these functions usually aim for high computational speed. For some applications, however, low resource usage is more important. Thus, this work presents a compact design for symmetric encryption, hash function, and Cryptographically Secure Random Number Generator. Its central element is a small AES-module, which is shared by all operations, leading to a lower resource usage than aggregated stand-alone solutions in previous work.
