A Review on Chaotic Map Based Cryptography
نویسنده
چکیده
this paper presents a review of Image cryptography techniques based on chaotic maps. The chaotic cryptography is gaining more attention than others because of its lower mathematical complexity & better Security. It also avoids the data spreading hence reduces the transmission cost & delay. The digital image cryptography which is based on chaotic systems utilizes the discrete non-linear system dynamics generally called chaotic maps. Depending upon the type of system many types of chaotic maps are available. By combining them a large number of cryptographic techniques could be designed in this paper we are presenting a review of some of those techniques.

Chaos-based Cryptography: an overview
We review some of the recent work on chaos-based cryptography. We argue that if a chaotic map f is used in cryptography, then it should be implemented as a bijection FM : D → D, where D is a finite set with cardinality M, such that, for large M, FM ‘approximates well’ the chaotic map f . Several examples, including chaotic block cypher and chaotic public-key encryption algorithm, are given.
متن کاملImproving security of double random phase encoding with chaos theory using fractal images
This study presents a new method based on the combination of cryptography and information hiding methods. Firstly, the image is encoded by the Double Random Phase Encoding (DRPE) technique. The real and imaginary parts of the encoded image are subsequently embedded into an enlarged normalized host image. DRPE demands two random phase mask keys to decode the decrypted image at the destination. T...

متن کاملImage encryption based on chaotic tent map in time and frequency domains
The present paper is aimed at introducing a new algorithm for image encryption using chaotic tent maps and the desired key image. This algorithm consists of two parts, the first of which works in the frequency domain and the second, in the time domain. In the frequency domain, a desired key image is used, and a random number is generated, using the chaotic tent map, in order to change the phase...
