Permutation based Image Encryption Technique
Information security is the key in the era of electronic data exchange. Images constitute a large portion of the electronic data. Confidentiality of color images is a difficult process. Most of the image encryption algorithms are complex and compromise on the quality of the image. This paper proposes a new image encryption based on random pixel permutation with the motivation to maintain the qu...
متن کاملImage Encryption Technique Based on Permutation and Combination
“Combination of Encryption and Decryption for secure communication is an application”. Here I am using Permutation and substitution technique to make our data more secure. It is concerned in hiding the information in secure and robust manner so that the confidentiality of the data remains. This paper also attempts to identify the requirement of good key generation algorithm and its decryption. ...
متن کاملCracking a hierarchical chaotic image encryption algorithm based on permutation
In year 2000, an efficient hierarchical chaotic image encryption (HCIE) algorithm was proposed, which divides a plain-image of size M×N with T possible value levels into K blocks of the same size and then operates position permutation on two levels: intra-block and inter-block. As a typical position permutation-only encryption algorithm, it has received intensive attention. The present paper an...
متن کاملA Chaos-based Image Encryption Scheme Using Permutation-Substitution Architecture
Recently, a great number of chaos-based image encryption algorithms have been proposed. But most of them are either deficient in security or complicated. In this paper, we propose a permutation-substitution image encryption scheme based on generalized Arnold map. Only one round of permutation and one round of substitution are performed to get the desirable results. The generalized chaotic Arnol...
متن کاملAlgorithm of Image Encryption based on Permutation Information Entropy
Criterion for choosing chaos map to drive image bit permutation based on chaos permutation information entropy is proposed. An algorithm for image bit permutation is designed based on the fact that the output trajectory of chaotic system is very unpredictable. Image smallest granularity scrambling, namely, bit space maximum scrambling is implemented by applying the chaos that has been selected....
