Chosen-Plaintext Cryptanalysis of a Clipped-Neural-Network-Based Chaotic Cipher
نویسندگان
چکیده
In ISNN’04, a novel symmetric cipher was proposed, by combining a chaotic signal and a clipped neural network (CNN) for encryption. The present paper analyzes the security of this chaotic cipher against chosen-plaintext attacks, and points out that this cipher can be broken by a chosen-plaintext attack. Experimental analyses are given to support the feasibility of the proposed attack.

Cryptanalysis of a cryptographic scheme based on delayed chaotic neural networks
Recently, Yu et al. presented a new cryptographic scheme based on delayed chaotic neural networks. In this letter, a fundamental flaw in Yu’s scheme is described. By means of chosen plaintext attack, the secret keystream used can easily be obtained. 2007 Elsevier Ltd. All rights reserved.
متن کاملCryptanalysis of a Cryptographic Algorithm that Utilizes Chaotic Neural Networks
This paper deals with the security and efficiency issues of a cryptographic algorithm which utilizes the principles of Chaotic Neural Network (CNN). The algorithm that we consider is the Delayed CNNBased Encryption (DCBE), which is an encryption algorithm based on the Delayed CNN. Although the cryptographic algorithm has its own salient characteristics, our analysis show that, unfortunately, th...

متن کاملCryptanalysis of Image Encryption Scheme Based on Chaotic Tent Map
With the development of chaos theory, many image encryption algorithmshave been designed using the properties associated withthechaotic map. The chaotic map shows high sensitivity to initial conditions and the sequence generated using chaotic map are unpredictable making it a good choice for performing encryption operation. But, without proper encryption algorithm design, encryption scheme desi...
