Cryptanalysis on stream cipher

WebMar 14, 2024 · Linear cryptanalysis is a general style of cryptanalysis based on discovering affine approximations to the element of a cipher. Attacks have been produced for block ciphers and stream ciphers. Linear cryptanalysis is one of the two most broadly used attacks on block ciphers and the other being differential cryptanalysis. WebThe stream cipher was implemented and tested in a Field Programmable Gate Array (FPGA) and was able to generate 8-bit width data streams at a clock frequency of 134 MHz, which is fast enough for Gigabit Ethernet applications. An exhaustive cryptanalysis was completed, allowing us to conclude that the system is secure.

WebA stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream ( keystream ). In a stream cipher, each plaintext digit is encrypted one at a time with the corresponding digit of the keystream, to give a digit of the ciphertext stream. WebMost ciphers will process the message (or at least generate the keystream) in chunks of more than one bit at a time. For block ciphers in streaming modes, the chunk size will typically equal the block size of the underlying block cipher.
