Standardized Symmetric Cryptography

Table of Contents

back to the main page

It can be hard to navigate all the esoteric codes of the different standardizing bodies. In this page, I try and list all the standards that contain symmetric algorithms.

The information on this page is gathered from public sources, typically from the summaries of the standards provided by the different institution. While some standards are totally free to read, others must be bought (for a hefty amount!); it is in particular the case for ISO standards. However, the algorithms are often publicly available via other channels. For instance, while the ISO standard specifying the AES is behind a paywall, the NIST one is not.

This list is a work in progress: if there are algorithms missing, do let me know!

International

ISO/IEC

For some reason, hash functions are always called "hash-function" in ISO/IEC standards.

18033: Encryption Algorithms

Part 1 (18033-1) General
This standard introduces all the notations and concepts needed by the other standards in this category.
Part 2 (18033-2) Asymmetric Ciphers
This one deals with "asymmetric encryption", i.e. it is not relevant here.
Part 3 (18033-3) Block Ciphers
Several algorithms are contained in this part. Some are in the body of the text while some are in the appendix.
64-bit Block Ciphers
  • TDEA (triple DES)
  • MISTY1
  • CAST-128
  • HIGHT
128-bit Block Ciphers
  • AES
  • Camellia
  • SEED
  • SM4 and Kuznyechik were in the process of being included via an amendment but it was cancelled because of the mystery surrounding the S-box of Kuznyechik (see Section "Results on the Russian Algorithms" in this page).
Part 4 (18033-4) Stream Ciphers
  • MUGI
  • SNOW 2.0
  • Rabbit
  • Decim v2
  • KCipher-2 (K2)
Part 5 (18033-5) Identity-based Ciphers
This part deals with identity-based encryption schemes, i.e. it is not relevant here.
Part 6 (18033-6) Homomorphic Encryption
This part deals with homomorphic encryption schemes, i.e. it is not relevant here.

10118: Hash functions

Part 1 (10118-1) General
This standard introduces all the notations and concepts needed by the other standards in this category.
Part 2 (10118-2) Hash-functions using an n-bit block cipher
This standard specifies modes of operation for building a hash function out of block cipher operating on n bits. Four such techniques are provided; they are aptly called "Hash-function 1", …, and "Hash-function 4".
Part 3 (10118-3) Dedicated hash-functions
  • RIPEMD-160
  • RIPEMD-128
  • SHA-1
  • SHA-256
  • SHA-512
  • SHA-384
  • WHIRLPOOL
  • Streebog
  • SM3
Part 4 (10118-4) Hash-functions using modular arithmetic
This standard deals with hash function built using functions traditionnally used in asymmetric cryptography. It contains MASH-1 and MASH-2.

29192: Lightweight Cryptography

Part 1 (29192-1) General
This standard introduces all the notations and concepts needed by the other standards in this category. It also contains the definition of lightweightness according to ISO.
Part 2 (29192-2) Block Ciphers
The NSA ciphers SIMON and SPECK were considered for inclusion in this standard but were eventually kicked out.
  • PRESENT
  • CLEFIA
Part 3 (29192-3) Stream Ciphers
  • Enocoro
  • Trivium
Part 4 (29192-4) Mechanisms using Asymmetric Techniques
Not relevant here.
Part 5 (29192-5) Hash-Functions
  • PHOTON
  • SPONGENT
  • Lesamnta-LW
Part 6 (29192-6) Message Authentication Codes (MACs) under development
  • LightMAC (mode of operation)
  • Chaskey
Part 7 (29192-7) Broadcast Authentication Protocols under development
Not relevant here.

National

USA

American standards are handled by the National Institute of Standards and Technology (NIST). Each document is a "Federal Information Processing Standard" (FIPS).

  • FIPS PUB 197: AES

Russia

Russian standards are handled by the Euro-Asian Council for Standardization, Metrology and Certification (EASC). Each of them is a "state union standard", which in Russian is abbreviated into "GOST".

  • GOST R 34.11-2012: Streebog (hash function)
  • GOST R 34.12-2015: Kuznyechik (block cipher)

Belarus

  • Bel-T (block cipher)
