Now days, more and more users store their important data in cloud. To ensure the security of the remotely stored data, users need to encrypt important data. From the point of data security which has always been important aspect of quality of service, cloud computing cause's new challenging security threats. Identity-based proxy re-encryption schemes have(More)
The problem of resource allocation in multiuser orthogonal frequency division multiplexing (OFDM) system is a combinatorial optimization problem. The conventional methods for the problem demand high computational complexity and are found to be long iterative algorithms. Intelligent techniques such as genetic algorithms (GAs), simulated annealing, particle(More)
Clustered voltage scaling (CVS) systems is a technique to decrease power dissipation. One of the design challenges in CVS is the efficient level converter with fewer overheads in power and delay. In this paper, we propose a novel implicit-pulsed level convert flip-flop that uses circuit techniques such as conditional discharge to reduce the overhead(More)
