Encryption is the most useful technique used for security of data during storage and transmission. A well-known encryption scheme called Double Random Phase encoding was introduced by Refregier Javidi. But due to its linear nature, this has been proven vulnerable against Known plaintext chosen attacks. Here in paper, we propose a chaotic map-based nonlinear that enhances DRPE images. Clifford a...

In order to overcome the shortcomings of standard compressive sensing (CS) encryption framework, a novel fusion application scheme CS and optical transformation technology is proposed. The proposed scheme, making full use feature achieve compression simultaneously, compresses encrypts two images into one image, which not only reduces storage space transmission bandwidth, but also improves secur...

This study presents a new method based on the combination of cryptography and information hiding methods. Firstly, the image is encoded by the Double Random Phase Encoding (DRPE) technique. The real and imaginary parts of the encoded image are subsequently embedded into an enlarged normalized host image. DRPE demands two random phase mask keys to decode the decrypted image at the destination. T...

the aim of the present study was the estimation of (co) variance components and genetic parameters for body weight of moghani sheep, using random regression models based on b-splines functions. the data set included 9165 body weight records from 60 to 360 days of age from 2811 moghani sheep, collected between 1994 to 2013 from jafar-abad animal research and breeding institute, ardabil province,...

In this paper a path planning algorithm is proposed for mobile robots. The algorithm utilizes piecewise cubic splines to create a smooth path in the 2D workspace of a mobile robot, while specifying targeted random control points based on the collision detection and penetration characteristics of the candidate paths. The main advantage of the proposed method compared to other probabilistic path ...

Mobile Ad Hoc Networks (MANET) are formed by wireless devices that intercommunicate without the utilization of any centralized entity that manages the radio resources. As direct communication is only possible for neighbour nodes, the transmission of information between distant devices is supported by the cooperation of intermediate nodes that retransmit and route their packets. Path duration is...
