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 ...

What is Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP)? Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP) is an encryption ...

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.

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 ...
