Taking the block cipher AES as an example, the criterion nonlinearity of S-box was introduced to quantify its resistance related to linear cryptanalysis; while the differential uniformity was used ...

Unlike traditional Cipher Block Chaining (CBC) modes, the Fast Cipher Block Chaining (FCBC) method, which is derived from CBC, reduces the encryption time per block by 15% to 25%.

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.

The algorithm expands a single message by up to 8 bytes. DES is a block cipher that encrypts data in blocks of 64 bits. SAS Proprietary This provides basic fixed encoding encryption services on all ...
