Stream cipher - Simple English Wikipedia, the free encyclopedia

WebThe mode of encryption that uses a self-synchronizing stream encryption where the initialization vector (IV) is encrypted and XORed is the Output feedback (OFB) mode. In OFB mode, the encryption of the IV generates a key stream, which is then XORed with the plaintext to produce the ciphertext. WebHowever, self-synchronizing stream ciphers fell obsolete, mainly because of the existence of a resynchronization mechanism in most modern synchronous stream ciphers. Families of Stream Ciphers.

WebMar 16, 2024 · In a synchronous stream cipher, the key stream is generated independently of the plaintext and ciphertext. In a self-synchronizing stream cipher, the previous ciphertext digits are used to compute the keystream. Stream ciphers typically execute at higher speeds and have lower hardware complexity.

WebMar 31, 2016 · By "self-synchronizing cryptosystem", I mean that the receiver attempting to recover the original plaintext will be mostly successful, with at most a dozen or so corrupted letters of plaintext corresponding to each missing ciphertext byte. Are all such cryptosystems necessarily self-synchronizing stream ciphers? In other words:

WebThis is called a binary additive stream cipher. Another approach uses several of the previous N ciphertext digits to compute the keystream. Such schemes are known as self-synchronizing stream ciphers or asynchronous stream ciphers.
