ISO/IEC 29192-3:2012
Information technology — Security techniques — Lightweight cryptography — Part 3: Stream ciphers
ISO/IEC 29192-3:2012 specifies two dedicated keystream generators for lightweight stream ciphers:
- Enocoro: a lightweight keystream generator with a key size of 80 or 128 bits;
- Trivium: a lightweight keystream generator with a key size of 80 bits.
