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 ...

Most encryption algorithms use the block cipher method, which codes fixed blocks of input. Others use the stream method, which encrypts one bit at a time.

A block diagram of the AES engine is shown in figure 2. Fig. 2: The Xtensa processor extended with AES cipher functionality. Figure 2 shows an Xtensa processor block diagram, configured and extended ...

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.
