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.

Abstract

Overview

Key topics and technical requirements

Keystream generator definitions - Formal descriptions of the initialization function (Init), next-state function (Next) and keystream function (Strm) required to define synchronous stream ciphers.
Specified algorithms - Two dedicated generators:
- Enocoro‑128v2: described with a 128‑bit key, 64‑bit IV, a 34‑byte internal state and a one‑byte keystream output per iteration. Uses arithmetic over GF(2^8) with the irreducible polynomial ψ(x) = x^8 + x^4 + x^3 + x^2 + 1.
- Trivium: included as a lightweight keystream generator with an 80‑bit key (standard specifies the generator; full algorithmic detail appears in the document).
Output and combination functions - Definition of binary-additive output functions (e.g., bitwise XOR of keystream and plaintext) and general output models for encryption/decryption.
Supporting normative and informative material - Normative object identifiers, test vectors (Annex B), implementation and usage guidance (Annex C), a feature comparison table (Annex D), and finite-field computation notes (Annex E).
Interoperability and patent notice - Cross-references to ISO/IEC 29192‑1 (general lightweight cryptography requirements) and acknowledgement of patent claims with licensing statements provided in the standard.

Practical applications

ISO/IEC 29192-3 targets environments where computational resources, power, memory, or bandwidth are constrained:

Securing communications for IoT devices, wireless sensor networks, RFID, and embedded systems
Protecting telemetry and control data in smart metering, industrial control, and wearables
Implementations on low-power microcontrollers or hardware-accelerated lightweight cryptographic modules

The specified keystream generators are designed for efficient implementation in software or hardware where traditional ciphers would be too heavy.

Who should use this standard

Cryptographic engineers and embedded systems designers selecting lightweight stream ciphers
Security architects for IoT and constrained-device deployments
Firmware developers and hardware implementers (ASIC/FPGA) needing standardized, interoperable keystreams
Certification bodies and product teams referencing ISO lightweight‑cryptography requirements
