List of stream ciphers

WebMy own research interest in stream ciphers found a natural re sonance in one of my doctoral students at the Swiss Federal Institute of Technology in Zurich, Rainer A. Rueppe1. As Rainer was completing his dissertation in late 1984, the question arose as to where he should publish the many new results on stream ciphers that had sprung from his research.

Introduction to Cryptography: One time pads and stream ciphers

WebThe key typically used with a stream cipher is known as a one-time pad. Mathematically, a one-time pad is unbreakable because it's always at least the exact same size as the … 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 corresponding digit of the keystream, to give a digit of the ciphertext stream. Since encryption of each digit … Meer weergeven 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 random digits. The keystream is combined … Meer weergeven Binary stream ciphers are often constructed using linear-feedback shift registers (LFSRs) because they can be easily … Meer weergeven 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 … Meer weergeven • United States National Security Agency documents sometimes use the term combiner-type algorithms, referring to algorithms that use some function to combine a Meer weergeven 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 … Meer weergeven 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. Meer weergeven 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.

Web1.2 Stream ciphers A stream cipher performs an encryption which is similar to the One-time Pad (OTP) en-cryption technique. It produces a large chunk of secret, random looking data and combines it with the plaintext to produce ciphertext. Without the exact same data chunk, the plaintext cannot be uncovered from the ciphertext. Web2. Stream ciphers could be vulnerable if used incorrectly, like to use the same key more than once. 3. Stream cipher is suitable when the input stream length is not predictable or the input buffering is limited. 4. The two approaches of Block cipher as below: • Each block will be encrypted independently than the others
