pattern generator. This LFSR has the characteristics of high speed, low power consumption and it is especially suited in processing environment where uniform distribution random numbers are required. A typical application of the pattern generator considered in this work is the testing of micro-electro-mechanical-system (MEMS), where low power

• 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 generator

Important LFSR-based stream ciphers include A5/1 and A5/2, used in GSM cell phones, E0, used in Bluetooth, and the shrinking generator. The A5/2 cipher has been broken and both A5/1 and E0 have serious weaknesses. LFSRs (linear feedback shift registers) provide a simple means for generating nonsequential lists of numbers quickly on microcontrollers. Generating the pseudo-random numbers only requires a right-shift operation and an XOR operation. Figure 1 shows a 5-bit LFSR. The linear feedback shift register is one of the most useful techniques for generating psuedo-random numbers.

Abstract. Pseudorandom generators based on linear feedback shift reg-isters (LFSR) are a traditional building block for cryptographic stream ciphers. In this report, we review the general idea for such generators, as well as the most important techniques of cryptanalysis. 1 Security Model 1.1 Shannon’s model
