This paper presents a high-performance reconfigurable hardware implementation of the Data Encryption Standard (DES) algorithm. This is achieved by combining pipelining concept with novel skew core key scheduling method and compared with previous illustrated encryption algorithms. The DES design is implemented on Xilinx Spartan-3e Field Programming Gate(More)
The complex business strategies of cloud services make Job scheduling a challenging issue. The mapping of user jobs onto a computing resource to achieve maximum benefit, satisfying the varying QoS of user's jobs, is the ultimate goal of a cloud provider. As this scheduling problem belongs to the family of combinatorial problems, it cannot be formulated as a(More)
Voltage scaling has been often used for reducing power dissipation of CMOS driven interconnects. An undesired effect observed due to voltage scaling is increase in propagation delay. Thus a trade off lies between power dissipation and propagation delay with voltage scaling. However, voltage scaling can result in overall reduction of power delay product(More)
Grid computing is the framework of computer systems that provides high performance computing environment. The challenging issue in grid computing is to design efficient and reliable task scheduling algorithms for efficient utilization of grid computing. In this paper, we are proposing a new Improvised Prioritized Deadline (IPD) based scheduling algorithm(More)
One of the important aspects in digital video applications is spatial and temporal characteristic. A very little progress has been achieved on spatio-temporal modeling of video data. In this paper, we present a fuzzy spatio-temporal model for video content description that supports spatio-temporal queries. Fuzzy definitions and membership functions of(More)
