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.

The creators of banking trojan programs in Brazil are using sophisticated block ciphers to encrypt their malware, making detection by anti virus products more difficult.

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.
