This is another video in my series of videos where I talk about Digital Logic. In this video, I show how you can make a Linear Feedback Shift Register, which is a circuit that allows you to generate pseudo-random numbers.

Just a simple linear feedback shift register (pseudorandom number generator) put together from stock mesecons parts. Could easily be made more efficient (fewer parts), but meh. The feedback network in use is 1 = 11 xor (13 xor (14 xor 16)).

What is SHRINKING GENERATOR? What does SHRINKING GENERATOR mean? Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. In cryptography, the shrinking generator is a form of pseudorandom number generator intended to be used in a stream cipher. It was published in Crypto 1993 by Don Coppersmith, Hugo Krawczyk, and Yishay Mansour. The shrinking generator uses two linear feedback shift registers. One, called the A sequence, generates output bits, while the other, called the S sequence, controls their output. Both A and S are clocked; if the S bit is 1, then the A bit is output; if the S bit is 0, the A bit is discarded, nothing is output, and we clock the registers again. This has the disadvantage that the generator's output rate varies irregularly, and in a way that hints at the state of S; this problem can be overcome by buffering the output. Despite this simplicity, there are currently no known attacks better than exhaustive search when the feedback polynomials are secret. If the feedback polynomials are known, however, the best known attack requires less than A•S bits of output. An interesting variant is the self-shrinking generator.

In this course you will learn the inner workings of cryptographic systems and how to correctly use them in real-world applications. The course begins with a detailed discussion of how two parties who have a shared secret key can communicate securely when a powerful adversary eavesdrops and tampers with traffic. We will examine many deployed protocols and analyze mistakes in existing systems. The second half of the course discusses public-key techniques that let two parties generate a shared secret key.

This is animation of the principle of A5/1 stream cipher used to provide over-the-air communication privacy in the GSM cellular telephone standard. It is one of seven algorithms which were specified for GSM use. A5/1 is used in Europe and the United States. A5/1 was developed in 1987, initially kept secret, the general design was leaked in 1994 and the algorithms were entirely reverse engineered in 1999 by Marc Briceno from a GSM telephone.

This project describes the minimized area hardware implementation of the Trivium Cipher based on the Shift register connected in Serial manner. The design was simulated using Xilinx ISE (Isim) to verify the correctness of the system. Also, it is synthesized using Composer Schematic for 130nm CMOS technology. The aim of the project is to reduce the area utilized by the Trivium Cipher. The shift registers are implemented using D flip flop with asynchronous reset input. The logic of D flip flop used for implementation is True Single Phase Clock type. The key stream generation consists of an iterative process which extracts the values of 15 specific state bits and uses them both to update 3 bits of the state and to compute 1 bit of key stream zi. The state bits are then rotated and the process repeats itself until the required 264 bits of key stream is generated.
