WebFeb 14, 2024 · All cryptographic methods aim to scramble data to hide it from outsiders. But unlike their counterparts, stream ciphers work on each bit of data in a message rather than chunking the message into groups and encrypting them in blocks. Stream ciphers rely on: Plaintext. You must have a message you'd like to encode. Keystreams. WebThe cryptanalyst then uses statistical analysis to search for signs of non-randomness in the ciphertexts, zeroing in on areas where the plaintexts differ. Every bit of the related ciphertexts should have a 50/50 chance of flipping; the cryptanalyst searches for areas where this is not true.
