Differing from known cryptosystems, the evolutionary cryptosystem features dynamically alterable and increasingly cryptographically strong encryption/decryption algorithms. Two papers showed that ...

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.

Based on the algorithm, they find 14-round and 16-round zero-correlation linear distinguishers of SKINNY-n-2n and SKINNY-n-3n, two versions of a widely used block cipher, respectively.

Block Cipher algorithms need to be used in certain specific modes to encrypt bulk data larger than a single block of just 128 bits. XTS mode, which stands for “XEX (Xor-Encrypt-Xor) with tweak and CTS ...

Block ciphers are a common cryptographic tool used in many existing algorithms, including the US government encryption standard DES—a variant of which has been used to serve secure web pages ...

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 ...

These algorithms take a block of plaintext and the encryption key as input and run them through a subprocess that repeats for a set number of rounds before outputting a finished ciphertext.

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 ...
