When using Built-In Self Test (BIST) for testing VLSI circuits, a major concern is the generation of proper test patterns that detect the faults of interest. Usually a linear feedback shift register (LFSR) is used to generate test patterns. We rst analyze the probability that an arbitrary pseudo-random test sequence of short length detects all faults. The term short is relative to the probabili...

A Low Transition LFSR(LT-LFSR) designed by modifying Linear Feedback Shift Register is proposed to produce low power test vectors which are given to Circuit under Test (CUT) to reduce the power consumption by CUT. This technique of generating low power test patterns is performed by increasing the co-relativity between the consecutive vectors by reducing the number of bit flips between successiv...

The filter generator is an important building block in many stream ciphers. We present here an attack that recovers the initial state of the hidden LFSR by detecting the positions where the inputs of the filtering function are equal to zero. This attack requires the precomputation of low weight multiples of the LFSR generating polynomial. By a careful analysis, we show that the attack complexit...

This research article proposed a logic BIST using linear feedback shift register (LFSR) to generate low power test patterns; It reduced the number of transitions at the input of the circuit-under-test using bit swapping technique. The designed architecture is programmed using Verilog HDL and simulated using CADENCE EDA Tool of 180 nm technology and also proposed design gives better performance ...

Linkable ring signatures can simultaneously provide the properties of anonymity, spontaneity as well as linkability. Linear feedback shift register (LFSR) sequence can be used to shorten the representation of elements in a field. This paper proposes an LFSR-based linkable ring signature scheme, whose main computation operations are performed in base field GF (q) whereas security properties are ...

Linear Consistency Test (LCT) is a well-known algebraic method of cryptanalysis of stream ciphers. In this paper, we use LCT in an attack on a noised irregularly clocked linear feedback shift register (LFSR). We show that it is possible to reconstruct the initial states of both the clocked and the clocking LFSR in this scheme by using an essentially algebraic attack method, such as LCT, as a bu...

In this paper we demonstrate a fast correlation attack on the shrinking generator with known connections. Our attack is applicable to arbitrary weight feedback polynomial of the generating LFSR and comparisons with other known attacks show that our attack offers good trade-offs between required keystream length, success probability and complexity. Our result confirms Golić’s conjecture that the...

We present a new technique for generating compact dictionaries for cause-effect diagnosis in BIST. This approach relies on the use of three compact dictionaries: (i) D1, containing compacted LFSR signatures for a small number of patterns and faults with high detection probability, (ii) an interval-based pass/fail dictionary D2 for the BIST patterns and for faults with relatively lower detection...
