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 ...

The two above-cited papers discussed the security of evolutionary block cipher against linear and differential cryptanalysis. Linear and differential cryptanalysis, introduced in the early 1990s ...

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.

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.
