WebNov 4, 2024 · The structure of the synchronizing stream cipher as shown in Fig. 4 is still based on the pseudorandom generator proposed by Arnault which is a concatenation of a LFSR and a slightly modified FCSR. The difference with … A stream cipher generates successive elements of the keystream based on an internal state. This state is updated in essentially two ways: if the state changes independently of the plaintext or ciphertext messages, the cipher is classified as a synchronous stream cipher. By contrast, self-synchronising stream ciphers update their state based on previous ciphertext digits.

Self-synchronizing cipher recovery from dropped bits

WebSelf-synchronizing ciphers can be considered as block ciphers operating in a single-bit feedback mode . To encrypt one plaintext bit, it is required to perform the encryption function of the whole block, which is much slower than the encryption function of the self-synchronizing cipher. WebFeb 3, 2024 · A self-synchronizing stream cipher, also known as ciphertext autokey, generates the keystream block as a function of the symmetric key and fixed size (N-bits) of the previous ciphertext block. Altering the ciphertext alters the content of the next keystream so that asynchronous stream ciphers can detect active attacks.
