NIST announced a public competition on Nov. 2, 2007 to develop a new cryptographic hash algorithm. Blake is one of the candidate among five finalist selected in round three of this competition. One of the major evaluation criteria of the candidate algorithm is efficient hardware implementation. In this paper compact area-efficient design of Blake-256 algorithm is implemented on FPGA. Horizontal Folding...
In the past decade, there was an enormous increase in the subscribers of Radio Access Networks (RANs) demanding ubiquitous quality of service (QoS), and continuous availability of connectivity. Therefore, Next Generation Networks (NGNs) are in high demand, which could imperatively combine multiple RANs to form a heterogeneous IP network. As mobile user moves across heterogeneous networks, there is...
In passive Radio Frequency IDentification (RFID) systems, tags do not have their own power source and they receive their operating energy from continuous modulated RF carrier transmitted by the reader. The tag while receiving this carrier randomly selects a slot and sends back its RN16 using backscatter modulation for purpose of its identification. The efficiency of the existing UHF RFID systems is...
