Cryptanalysis of a New Chaotic Cryptosystem Based on Ergodicity∗
This paper analyzes the security of a recent cryptosystem based on the ergodicity property of chaotic maps. It is shown how to obtain the secret key using a chosenciphertext attack. Some other design weaknesses are also shown.
متن کاملCryptanalysis of a discrete chaotic cryptosystem using external key
In recent years, a growing number of cryptosystems based on chaos have been proposed, many of them fundamentally flawed by a lack of robustness and security. In this Letter, we explain how to break a very recent block cipher algorithm based on the logistic map. This cryptosystem uses a 128-bit external key to derive the initial condition and number of iterations, but in a weak way allowing for ...
متن کاملCryptanalysis of a Chaotic Image Encryption Method
The security of digital images attracts much attention recently, and many image encryption methods have been proposed. In ISCAS2000, a new chaotic key-based algorithm (CKBA) for image encryption was proposed. This paper points out CKBA is very weak to the chosen/known-plaintext attack with only one plainimage, and its security to brute-force ciphertext-only attack is overestimated by the author...
متن کاملCryptanalysis of the Chaotic-Map Cryptosystem Suggested at EUROCRYPT'91
In this conference, Habutsuu1] suggested a cryptosystem based on iterating a chaotic map. In this paper several properties of this cryptosystem are studied and two cryptanalytic attacks are described.
متن کاملCryptanalysis of a novel cryptosystem based on chaotic oscillators and feedback inversion
An analysis of a recently proposed cryptosystem based on chaotic oscillators and feedback inversion is presented. It is shown how the cryptosystem can be broken when Duffing’s oscillator is considered. Some implementation problems of the system are also discussed.
