Linear Feedback Shift Register
A stream cipher is a symmetric cipher which operates with a time-varying transformation on individual plaintext digits. By contrast, block ciphers operate with a fixed transformation on large blocks of plaintext digits. More precisely, in a stream cipher a sequence of plaintext digits, m0m1 . . ., is encrypted into a sequence of ciphertext digits c0c1 . . . as follows: a pseudorandom sequence s...
متن کاملA New Chaotic Dynamical System and Its Usage in a Novel Pseudorandom Number Generator with a Linear Feedback Register Structure
In this paper we propose a new chaotic discrete dynamical system and we prove, theoretically and numerically, its complex behavior, using Lyapunov exponent, bifurcation diagram and fractal dimensions of the attractor. Then, we use the proposed chaotic dynamical system in a new pseudorandom number generator having a structure similar to a linear feedback register. In the end, we present the resu...
متن کاملA Pseudorandom Bit Generator based on Chaotic Coupled Map Lattices
In this paper, we discuss the properties of making a deterministic algorithm suitable to generate a pseudo random sequence of numbers: high value of Kolmogorov-Sinai entropy, high dimensionality of the parent dynamical system, and very large period of the generated sequence. We propose the chaotic coupled map lattices as a pseudo random number generator. We show what chaotic features of the cou...
متن کاملData Encryption with Linear Feedback Shift Register
A data encryption technology which ensures secrecy of the data while being transferred over a long distance. It can provide about 80-85% data security as decoding of data involves inverting the feedback function or generating the binary sequence which will help in retrieving the data after some recombination operation.
متن کاملFeedback Shift Register Sequences
Feedback Shift Register (FSR) sequences have been successfully implemented in many communication systems for their randomness properties and ease of implementation. These include ranging and navigation systems, spread spectrum communication systems, CDMA mobile communication systems, and crypto systems such as streamciphers. This article gives a brief overview of FSR sequences, both linear and ...
