We propose a novel methodology to design Block Cipher functions. This methodology is illustrated with the design of a specific block cipher function Maya. Our design philosophy is to derive the SBoxes themselves from the secret key. This makes breaking any round function equivalent to guessing all the key-bits. Advantages of our design include much larger key sizes in relation to the block size...

purpose: in recent years high explosive bomb attacks have been increasingly directed against   civil structures by various terrorist organizations. this paper describes a numerical method for   assessing the interaction of high explosive air blast within the complex geometrical type of a   congested urban environment.   materials and methods: the first step in predicting blast effects on a targ...

Understanding linkage block size and molecular mechanisms of recombination suppression is important for plant breeding. Previously large linkage blocks ranging from 14 megabases to 27 megabases were observed around the rice blast resistance gene Pi-ta in rice cultivars and backcross progeny involving an indica and japonica cross. In the present study, the same linkage block was further examined...

TURBO-BLAST is a novel multitransmit multireceive (MTMR) antenna scheme for high-throughput wireless communications. It exploits the following ideas: the Bell Labs layered space time (BLAST) architecture; random layered space-time (RLST) coding scheme by using independent block codes and random space-time interleaving; sub-optimal turbo-like receiver that performs iterative decoding of the RLST...

Firing sequence of blastholes in blasting is an inherent part the blast design for various reasons that range from spatial requirements to control throw during surface mines. Despite several such patterns vogue, role firing sequences defining size fragmented block sizes not properly understood. The V-type pattern believed improve fragmentation because collision moving fragments process, thus re...
