Image encryption using chaotic logistic map
In recent years, the chaos based cryptographic algorithms have suggested some new and efficient ways to develop secure image encryption techniques. In this communication,wepropose a newapproach for image encryption basedon chaotic logisticmaps in order tomeet the requirements of the secure image transfer. In the proposed image encryption scheme, an external secret key of 80-bit and two chaotic ...
متن کاملA Joint SVD based Watermarking and Encryption Scheme using Chaotic Logistic Map
Copyright protection and secrecy of some sensitive data is essential in this present digital era which deals with the advances in cloud computing and big data analytics. Digital watermarking is a popular method for copyright protection whereas cryptography takes care in hiding information as well as for secure transmission of data in a manner that is unreadable to a third party. Combination of ...
متن کاملImage encryption using the two-dimensional logistic chaotic map
Chaos maps and chaotic systems have been proved to be useful and effective for cryptography. In this paper, the two-dimensional logistic map with complicated basin structures and attractors are first used for image encryption. The proposed method adopts the classic framework of the permutation-substitution network in cryptography and thus ensures both confusion and diffusion properties for a se...
متن کاملA New Encryption Method Using Chaotic Logistic Map
Encryption is to rearrange the message into difference form so that the message is keep secret. The goal of encryption is to provide an easy and inexpensive means of encryption and decryption to all authorized users in possession of the appropriate key and difficult and expensive means to estimate the plain text without use of the key Nowadays the Internet becomes popular and encryption technol...
متن کاملA Novel Lossless Image Encryption Method using DNA Substitution and Chaotic Logistic Map
Presently, there is a growth in the transmission of image and video data. Security becomes a main issue. Very strong image cryptographic techniques are a solution to this problem. There is a use of a randomly generated public key and based on that there is an application of DNA algorithm. In the proposed method DNA algorithm based substitution is used for spatial domain bit permutation. Here th...
