A Public-Key Approach of Selective Encryption for Images
نویسندگان
چکیده
Data security protection is essential for most multimedia data transmissions today. Classical multimedia content protection is dominated by symmetric encryption methods. This paper explores the possibility of public-key media content encryption. The key problem to the asymmetric selective encryption is formalized and defined as the “bounded plaintext problem”. Possible solutions to this problem are proposed. A public-key multimedia encryption model is developed and the implementation results are provided.

A stack-based chaotic algorithm for encryption of colored images
In this paper, a new method is presented for encryption of colored images. This method is based on using stack data structure and chaos which make the image encryption algorithm more efficient and robust. In the proposed algorithm, a series of data whose range is between 0 and 3 is generated using chaotic logistic system. Then, the original image is divided into four subimages, and these four i...
متن کاملQTRU: quaternionic version of the NTRU public-key cryptosystems
In this paper we will construct a lattice-based public-key cryptosystem using non-commutative quaternion algebra, and since its lattice does not fully fit within Circular and Convolutional Modular Lattice (CCML), we prove it is arguably more secure than the existing lattice-based cryptosystems such as NTRU. As in NTRU, the proposed public-key cryptosystem relies for its inherent securi...
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...
