Image encryption using chaotic sequence and its cryptanalysis
Sagade A.G Sagade A.G · IOSR Journal of Computer Engineering · 2013
MultiMedia is growing application in various areas ,security is an important issue in communication and storage of images and Encryption is a very common technique to uphold image security.Many encryption systems have been introduced among them; image encryption using chaotic sequence has many proposals.In this paper we analyze the security weakness of the proposal.We use chosen plain-text attack and known plain-text attack to reveal the secret parameters of the algorithm.That is to say, this method is not at all secure from the point of cryptography.
