Light-induced self-synchronizing flow patterns

Light-induced self-synchronizing flow patterns

In this paper, we present the observation of light-induced selfsynchronizing flow patterns in a light–fluid system. A light beam induces local flow patterns in a fluid, which oscillate periodically or chaotically in time. The oscillations within different regions of the fluid interact with each other through heatand surface-tension-induced fluid waves, and they become synchronized. We demonstra...

Optimized Self-Synchronizing Mode of Operation

Modes of operation adapt block ciphers to many applications. Among the encryption modes, only CFB (Cipher Feedback) has both of the following properties: Firstly it allows transmission units shorter than the block-cipher length to be encrypted and sent without delay and message expansion. Secondly, it can resynchronize after the loss of such transmission units. However, CFB is ine cient in such...

Self-Synchronizing Reversible Variable Length Codes

A reversible variable-length code (RVLC) is a code in which the bit stream formed by a portion of a codeword, or by the overlapped portion of two or more adjacent codewords, is not a valid codeword. A self-synchronizing RVLC allows for a sequence of codewords to be decoded either backwards or forwards without any external synchronization. In this article, we present an algorithm for constructin...

The Self-synchronizing Stream Cipher Moustique

We present a design approach for hardware-oriented selfsynchronizing stream ciphers and illustrate it with a concrete design called Moustique. The latter is intended as a research cipher: it proves that the design approach can lead to concrete results and will serve as a target for cryptanalysis where new attacks may lead to improvements in the design approach such as new criteria for the ciphe...
