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 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 ...
متن کاملOn Generalized Inversive Congruential Pseudorandom Numbers
The inversive congruential method with prime modulus for generating uniform pseudorandom numbers has several very promising properties. Very recently, a generalization for composite moduli has been introduced. In the present paper it is shown that the generated sequences have very attractive statistical independence properties.
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 کاملHigh Efficiency Feedback Shift Register: σ−LFSR?
We introduce a new kind of word-oriented linear feedback shift register called σ−LFSR which is constructed with the instructions of the modern processor and have fast software implementation. We offer an algorithm to search for good primitive σ−LFSR. In particular, we give two examples HHZ-1 and HHZ-2 and compare their efficiency and security with those of the LFSRs appearing in stream ciphers ...
