On the Security of Y-00 under Fast Correlation and Other Attacks on the Key [PDF]

, 2006
The potential weakness of the Y-00 direct encryption protocol when the encryption box ENC in Y-00 is not chosen properly is demonstrated in a fast correlation attack by S. Donnet et al in Phys. Lett. A 35, 6 (2006) 406-410.

On the Design of Perceptual MPEG-Video Encryption Algorithms [PDF]

, 2006
In this paper, some existing perceptual encryption algorithms of MPEG videos are reviewed and some problems, especially security defects of two recently proposed MPEG-video perceptual encryption schemes, are pointed out.

Simulating Auxiliary Inputs, Revisited [PDF]

, 2016
For any pair $(X,Z)$ of correlated random variables we can think of $Z$ as a randomized function of $X$. Provided that $Z$ is short, one can make this function computationally efficient by allowing it to be only approximately correct.

Hybrid Cipher System using Neural Network

مجلة بغداد للعلوم, 2008
The objective of this work is to design and implement a cryptography system that enables the sender to send message through any channel (even if this channel is insecure) and the receiver to decrypt the received message without allowing any intruder to ...

Quantum Noise Randomized Ciphers

, 2006
We review the notion of a classical random cipher and its advantages. We sharpen the usual description of random ciphers to a particular mathematical characterization suggested by the salient feature responsible for their increased security.

Transparent code authentication at the processor level [PDF]

, 2009
The authors present a lightweight authentication mechanism that verifies the authenticity of code and thereby addresses the virus and malicious code problems at the hardware level eliminating the need for trusted extensions in the operating system.

Side Channel Attack On Stream Ciphers: A Three-Step Approach To State/Key Recovery

Transactions on Cryptographic Hardware and Embedded Systems, 2022
Side Channel Attack (SCA) exploits the physical information leakage (such as electromagnetic emanation) from a device that performs some cryptographic operation and poses a serious threat in the present IoT era. In the last couple of decades, there have

A Novel Hybrid Elementary Cellular Automata and Its Application in a Stream Cipher

Applied Sciences
The elementary cellular automata (ECAs) under the chaotic rule possess long periodicity and are widely used in pseudo-random number generators. However, their period is limited, related to the rule and the number of cells.

Stream Cipher Using Genetic Algorithm [PDF]

Al-Rafidain Journal of Computer Sciences and Mathematics, 2009
The research tackles newly suggested method  in generating the random key used in stream cipher, by generating the key randomly using rand function and then applying randomness conditions if the produced key satisfy the conditions then its accepted key ...

Strike: Stream Cipher Based on Stochastic Lightning Strike Behaviour

Applied Sciences, 2023
There is an increasing need for secure and fast encryption algorithms to support applications and communication protocols, and business models. In this paper, we present an alternative stream cipher (Strike) inspired by the stochastic behaviour of ...
