Feedback with Carry Shift Registers (FCSRs) are a promising alternative to Linear Feedback Shift Registers (LFSRs) for the design of stream ciphers. The main difference between these two automata lies in the computation of the feedback. While LFSRs use simple bitwise addition, FCSRs use addition with carries.

A variety of different clock-controlled stream ciphers and attacks on them have been described in a number of papers. However, few word-oriented algorithms with an irregular clocking mechanism have been proposed. This paper proposes a new design of irregular clocking for word-oriented stream ciphers that is dynamic feedback control and show analysis ...

Introduction to Stream Ciphers
2019The word cryptology comes from two Greek roots meaning “hidden” and “word”, and is the generic name used to describe the entire field of secret communications. Cryptology clearly splits into two opposite but complementary disciplines: cryptography and cryptanalysis.

In this paper we propose a new synchronous stream cipher; the FBG stream cipher. This cipher is based on FBG (fuzzy bit generator) PN bit generator. The FBG cipher has been designed to produce keystream with guaranteed randomness properties; i.e. passing all the 16 tests of the NIST statistical test suite.

The family of stream ciphers MICKEY (which stands for Mutual Irregular Clocking KEYstream generator) is aimed at resource-constrained hardware platforms. It is intended to have low complexity in hardware, while providing a high level of security.

The rakaposhi Stream Cipher [PDF]
, 2009 In this paper, we introduce the rakaposhi stream cipher. The algorithm is based on Dynamic Linear Feedback Shift Registers, with a simple and potentially scalable design, and is particularly suitable for hardware applications with restricted resources.

Spectrum Analysis of the Stream Cipher
Applied Mechanics and Materials, 2012Classical cryptography theory holds that the true random sequence is better than any pseudorandom sequence on the security of stream cipher. So people prefer the pseudorandom sequence with long-period to the pseudorandom sequence with short-period. In this paper, it is proved through power spectrum analysis that the pseudorandom sequence with long ...
