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. WebStream ciphers are symmetric encryption algorithms based on the concept of pseudorandom keystream generator. In the typical case of a binary additive stream cipher, the key and an additional parameter named initialization vector (IV) are used to generate a binary sequence called keystream which is bitwise tpl0651

WebIn this paper we propose a Guess-and-Determine based initial state recovery attack on Polar Bear, one of the ECRYPT stream cipher project candi-dates. The computational complexity and success proba ... 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. The keystream is produced by a keystream generator which takes a secret key and an initial value (IV) as a seed and generates a long pseudo-random sequence of 0s and 1s.

WebWithout this option, fopen opens the file as a text stream. Text and binary streams differ in several ways: The data read from a text stream is divided into lines which are terminated … In the most common form, binary digits are used ( bits ), and the keystream is combined with the plaintext using the exclusive or operation (XOR). This is termed a binary additive stream cipher . In a synchronous stream cipher, the sender and receiver must be exactly in step for decryption to be successful. See more A 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 … See more Binary stream ciphers are often constructed using linear-feedback shift registers (LFSRs) because they can be easily implemented in hardware and can be readily analysed mathematically. The use of LFSRs on their own, however, is insufficient to … See more For a stream cipher to be secure, its keystream must have a large period, and it must be impossible to recover the cipher's key or internal state from the keystream. Cryptographers … See more Stream ciphers can be viewed as approximating the action of a proven unbreakable cipher, the one-time pad (OTP). A one-time pad uses a keystream of completely See more 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 … See more Instead of a linear driving device, one may use a nonlinear update function. For example, Klimov and Shamir proposed triangular functions (T-functions) with a single cycle on n-bit words. See more Stream ciphers are often used for their speed and simplicity of implementation in hardware, and in applications where plaintext comes in quantities of unknowable length like a secure wireless connection.
