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. THIS DEFINITION IS FOR ...

Stream ciphers encrypt data by generating a stream of random bits, called a keystream, and combining it with the plaintext using a bitwise operation, such as XOR. The keystream is derived from a ...

The first constraint disqualifies any block cipher larger than 8 bits. On WebAssembly, AES-based constructions are either very slow or unprotected against side channel attacks. That leaves us with ...

the recommended choice from djb XSynd stream cipher as an interesting and nontraditional candidate also based on assumptions from coding theory; used NUMS (it requires lot of NUMS) are explained in ...

Abstract: In this letter, we conduct an experiment of quantum noise stream cipher scheme based on 3-channel-QAM mapping and DFTs-OFDM in optical back-to-back and 160km standard single mode fiber. The ...
