An 8- and 12-bit block AES cipher

TL;DR

This paper documents a rare, minimalistic 8- and 12-bit block AES cipher implementation, providing detailed exposition and Java source code for educational and research purposes.

Contribution

It introduces and details a tiny AES cipher with 8- and 12-bit blocks, which is uncommon and useful for understanding cryptographic principles in constrained environments.

Findings

Provides a fully documented implementation of tiny AES cipher.

Offers Java source code for educational use.

Highlights the design considerations for small block ciphers.

Abstract

Because it is so unusual, or hard to find, or expository, a truly tiny 8- or 12-bit block AES (Rijndael) cipher is documented here, along with Java source code.
