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 ...

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 National Security Agency (NSA) is offering two families of encryption algorithms, known as block ciphers, intended to provide a level of security for such processes as authentication or ...

However, the report said Adobe had used a single block cipher throughout the database, resulting in identical passwords having the same ciphertext in the database.

An encryption method that works with continuous streams of input rather than fixed blocks. Bytes of plaintext go into the stream cipher, and bytes of encrypted text come out the other end. RC4 is ...
