a Pseudo-Random Number Generator (PRNG) can sometimes be good enough. A Linear Feedback Shift Register (LFSR) provides a simple form of hashing.

An LFSR (Linear Feedback Shift Register) will generate a non-repeating pseudo-random sequence of integers, that is bounded between 1 and a power of 2. The changes add a new generator, that takes a size (pixel index) as an argument, and from here will return a sequence of 2^n-1 (where n is the largest power of 2 below size) integers, seemingly • An LFSR generates periodic sequence – must start in a non-zero state, • The maximum-length of an LFSR sequence is 2n-1 – does not generate all 0s pattern (gets stuck in that state) • The characteristic polynomial of an LFSR generating a maximum-length sequence is a primitive polynomial • A maximum-length sequence is pseudo-random: LFSR-vhdl-generator. This project is based on a simple Python library and a Vhdl template for the generation of arbitary LFSR based pipelined pseudorandom number generators [1].

Digital based random number generators which are used in various cryptography applications are becoming more important. However, predictable random numbers generated by the are fatal to applications. In this study, we have identified the disadvantages (i.e., periodic and predictable random sequences) of the linear-feedback shifter register (LFSR) and proposed a polynomial modulator to …

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We give the results of a computer search for maximally-equidistributed combined linear feedback shift register (or Tausworthe) random number generators, whose components are trinomials of degrees slightly less than 32 or 64. These generators are fast and have good statistical properties. Pseudorandom number generators (PRNGs) are important role in cryptography application. Hardware based random number generators become faster. Field Programming Gate Arrays (FPGA) is one of the most valuable devices in hardware industry. This paper presents multibit linear feedback shift register (LFSR) based PRNGs circuit designed with hardware description languages (HDL).

LFSR and Ring Generator. An n-bit Linear Feedback Shift Register (LFSR) consists of 'n' memory elements (or flops) and XOR gates. There are basically two

The configurable parameters are: LFSR length: length in bits of the shift register; Tap list: indices of shift register entries for the linear-feedback. Abstract. Pseudorandom generators based on linear feedback shift reg-isters (LFSR) are a traditional building block for cryptographic stream ciphers.
