Information security and confidentiality has become of prime concern and importance as a result of the notifiable and explosive growth of the internet. Also, with the growth of information technology and communication techniques, unauthorized access for sensitive data increases daily. There are a lot of widely used techniques in the communication and computer security fields like; cryptography and...
Research has focused on static large graph management. However, most of real-world networks evolve with time. Managing these evolving networks has attracted much attention in recent years. The networks' evolved data can be kept in a dynamic graph to improve the expressiveness and the quality of search queries as well as snapshot(s) retrieval. Storing the continuous evolution of the network in a dynamic...
The information capacity is growing significantly as well as its level of importance and its transformation rate. In this paper, a blind data hiding hybrid technique is introduced using the concepts of cryptography and steganography in order to achieve double layer secured system. The proposed method consists of two phases: phase one is converting the message to DNA format using the proposed n-bits...
This paper demonstrates the inspiration of using communication technique between nanorobots and the movements of them in a swarm for the purpose of target area tracking and arrival inside human blood streaming environment. So, the blood elements and physical properties must be considered. The communication and movement problems of nanorobots are carried out in a self-organized way by applying modified...
This paper presents empirical results of the effect of the global position information on the performance of the modified local navigation algorithm (MLNA) for unknown world exploration. The results show that global position information enables the algorithm to maintain 100% success rate irrespective of initial robot position, movement speed, and environment complexity. Most mobile robot systems accrue...
