Design of Efficient Linear Feedback Shift Register for BCH Encoder

Design of efficient Linear Feedback Shift Register for BCH Encoder

The sequential circuit designed was Look-Ahead Transformation based LFSR in which a hardware complexity was present and it may limit their employ in many applications. The design of efficient LFSR for BCH encoder using TePLAT (Term Preserving Look-Ahead Transformation) overcame this limitation by opening the employ of minimizing the iteration bound and hardware complexity in wide range of appli...

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...

Efficient Linear Feedback Shift

Data 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.

Shift - Register Synthesis and BCH Decoding l

It is shown in this paper that the iterative algorithm introduced by Berlekamp for decoding BCH codes actually provides a general solution to the problem of synthesizing the shortest linear feedback shift register capable of generating a prescribed finite sequence of digits. The shit-register approach leads to a simple proof of the validity of the algorithm as well as providing additional insig...
