Abstract: Elliptic Curve Discrete Log Problem (ECDLP) is the underlyingbasis of many popular Public Key Scheme like Diffie-Hellman and ElGamal. The strength of such public key schemes is based on the difficulty of solving the ECDLP. The best method for solving the ECDLP has time complexity exponential in the size of the underlying field. ECDLP based cryptosystems are popular because they provide good security at key sizes much smaller than number theoretical Public Key Schemes like RSA cryptosystem......

Abstract: Cloud computing can save an organization's time and money but trusting the system is very much important because the real asset of any organization is the data which they share in the cloud to use the needed service by putting it directly in the relational database.No organization can transfer its data or information to a third party until a bridge of trust is built.......

Abstract: The aim of this paper is to introduce an automatic student modeling approach for identifying learning style in learning management systems according to Felder Silverman Learning Style Model (FSLSM).This paper proposes the use of fuzzy cognitive maps FCMs as a tool for identifying learner's learning style to individualizing each learner's according to their needs. FCMs are a soft computing tool which is a combination of fuzzy logic and neural network. Result shows that according to this model student learning style can be detected which give high precision value.

Abstract: WSN uses a large number of wireless sensor nodes to collect information from their sensing terrain.WSN is battery-powered devices in which energy-saving is a crucial issue. Every node in sensor network consist of three subsystems, first sensor subsystem which senses the environment, the second processing subsystem which do local computation on sensed data and third communication subsystem which is responsible for message exchange. In this paper, various literature was reviewed on different data collection mechanism on energy efficiency and presented the current scenario

Abstract: Gates and circuits made of Quantum Cellular Automata are subject to manufacturing errors due to imprecision of measurement. Our work examines the use of game theory optimization to correct Gaussian measurement error in Quantum Cellular Automata studies. We examine the use of game theory as a possible tool of optimization, specifically that of mixed strategy games. Simulation results show improvement in standard deviation of noise for mixed strategy games, as well as improvement in average polarity of gate.
