Chaotic Filter Bank for Computer Cryptography
A chaotic filter bank for computer cryptography is proposed. By encrypting and decrypting signals via a chaotic filter bank, the following advantages are enjoyed: 1) one can embed signals in different frequency bands by employing different chaotic functions; 2) the number of chaotic generators to be employed and their corresponding functions can be selected and designed in a flexible manner bec...
متن کاملCryptanalysis of a computer cryptography scheme based on a filter bank
This paper analyzes the security of a recently-proposed signal encryption scheme based on a filter bank. A very critical weakness of this new signal encryption procedure is exploited in order to successfully recover the associated secret key.
متن کاملReconfigurable hardware implementation of a modified chaotic filter bank scheme
Chaotic filter bank schemes have been proposed in the research literature to allow for the efficient encryption of data for real-time embedded systems. Some security flaws have been found in the underlying approaches which makes such a scheme unsafe for application in real life scenarios. In this paper, we first present an improved scheme to alleviate the weaknesses of the chaotic filter bank s...
متن کاملCryptography Using Chaotic Neural Network
The goal of any cryptographic system is the exchange of information among the intended users without any leakage of information to others who may have unauthorized access to it. In 1976, Diffie and Hellmann found that a common secret key could be created over public channel accessible to any opponent. Since then many public key cryptography have been presented which are based on number theory a...
