Webabout 20 years ago [9]. A common type of stream cipher is the binary additive stream cipher, in which the keystream, the plaintext, and the ciphertext are binary sequences. … Webthe cryptanalysis of some binary additive stream ciphers, in this section we present some facts about it. Definition 3. 1 If the affine function wx (~ 1 makes the following for- mula achieve its minimal value, E (f(x) (~wx(~ /), wE GF(2)", l E GF(2) then wx (~ l is called the best affine approximation of f(x).
WebDec 30, 2015 · Confidentiality Algorithm: EEA3. Built on top of ZUC, EEA3 is a binary additive stream cipher utilizing ZUC keystream words in the obvious way: Ciphertext bits are message bits XOR-summed with ZUC keystream word bits. WebThis paper deals with the merger of the two lightweight stream ciphers – A5/1 and Trivium. The idea is to make the key stream generation more secure and to remove the attacks …
Weba binary additive stream cipher. There is abundant theoretical knowledge on stream ciphers, and various design principles for stream ciphers have been proposed and extensively analyzed. For instance, in the modern stream ciphers, a secret key accompanied with a public initialization vector (IV) are used WebIn the most common form, binary digits ( bits) are used, and the keystream is combined with the plaintext using the exclusive or operation (XOR). This is termed a binary additive …
WebThe stream ciphers considered in this chapter are binary additive stream ciphers, that is, a ciphertext bitstring is produced by adding a plaintext bitstring and a binary keystream. …
WebA binary additive stream cipher generates a stream of pseudo-random symbols, called the keystream, Z, based on a secret key Kand an initialization vector, IV [38].

Synchronous and asynchronous stream ciphers could also be classified as additive. For example, binary additive would indicate that the cipher gamma output is combined by xor with the plain text to produce the cipher text.
