Due to The increase of using the international network, the multimedia data security becomes the most significant factor to protect data. Encryption algorithms are covers some of data security requirement like confidentiality, prevent eavesdropping of data and integrity but the others requirements like copyright protection and data authentication which can be satisfy by sharing with another security technique which is called digital watermarking. So in this paper, digital watermarking and image encryption algorithm based on chaotic map are merging in one system to satisfy these objectives. The experimental results show The proposed scheme has a high security and, the correlation coefficients approach to zero(0.008) and high speed(0.5)second with good quality of extracted image after decrypted image(37dB).

Cryptanalysis of Stream Cipher System Using Particle Swarm Optimization Algorithm

Sharifi; Hussein Ali Mohammed Al

journal of kerbala university, Volume 6, Issue 2, Pages 384-394

The meaning of the Particle Swarm Optimization (PSO) refers to a relatively new family of algorithms that may be used to find optimal (or near optimal) solutions to numerical and qualitative problems.
Stream ciphers are an important class of encryption algorithms. Shift register sequences are used in both cryptography and coding theory. There is a wealth of theory about them; stream ciphers based on shift registers have been the workhorse of military cryptography since the beginnings of electronics.
This paper aims to implement cryptanalysis attack algorithms on stream cipher systems using plaintext attack (or part from it), choosing one Linear Feedback Shift Register (LFSR), since its considered as a basic unit of stream cipher systems, in the performance of PSO by solving Linear Equations System (LES) for any number of variables of the output of LFSR.
The application divided into two stages, first, constructing LES’s for the LFSR, and the second, is attacking the variables of LES’s which they are also the initial key values the of LFSR.
