RFCs for block ciphers

These RFCs give specifications for the block ciphers themselves.

• RFC 2040, RC5
• RFC 2144, CAST-128
• RFC 2612, CAST-256
• RFC 3713, Camellia
• RFC 4629, SEED

There are other RFCs covering block cipher modes of operation and how these ciphers should be used in protocols such as IPsec, Open PGP, SSL and SSH. For details, see the linked articles or use RFC search.

Indexes and literature surveys

The Block Cipher Lounge was once an excellent index of current research, with links to design papers and cryptanalytic results for all the well-known block ciphers. However, it is now out-of-date.

Literature surveys:

• A Report on Block Ciphers (Literature Survey), concentrating on Feistel ciphers, from the Indian National Aeronautics Lab
• Survey and benchmark of block ciphers for wireless sensor networks, partly literature survey and partly requirements analysis for wireless applications
• Cryptanalysis of Block Ciphers: A Survey by Standaert et al.
• S-Box Design: A Literature Survey from Terry Ritter
