Block ciphers are invertible symmetric key cryptographic algorithms. Here, symmetric means that the same cryptographic key is used to both encrypt and decrypt messages. The key is used to transform ...

Cipher block chaining (CBC) is a mode of operation for a block cipher-- one in which a sequence of bits are encrypted as a single unit, or block, with a cipher key applied to the entire block. Cipher ...

For decades, a quiet intuition shaped how engineers approached the Generalized Feistel Network — the multi-branch block cipher architecture behind Sony's CLEFIA, the international lightweight ...

Zero-correlation linear cryptanalysis is an important method to analyze the security of block ciphers. But there are few works on zero-correlation linear attacks combined with the related-key setting.

As you likely know, one of the biggees that the newly ratified 802.11i security standard will bring to the wireless LAN table is Advanced Encryption Standard, the U.S. government’s chosen standard ...
