In those papers, we exploited separately the security of evolutionary block cipher against multidimensional linear cryptanalysis and differential cryptanalysis.

Bytes of plaintext go into the stream cipher, and bytes of encrypted text come out the other end. RC4 is an example of a stream cipher (see RC4). Contrast with block cipher.

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 ...

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.

Others use the stream method, which encrypts one bit at a time. See mode of operation, cryptography, security protocol, stream cipher, block cipher and algorithm.

RC2 is a block cipher that encrypts data in blocks of 64 bits. The size of the output of the algorithm is always a multiple of the block size. The RC2 key size can range from 8 to 256 bits. RC4 A ...

This shows that our vector stream cipher IP cores are implemented as reconfigurable encryption processors with retaining multi ten Giga bit/s processing speed. CONCLUDING REMARKS We introduce an IP ...

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.
