Current theories of massless free particle assume unitary space inversion and anti-unitary time reversal operators. In so doing robust classes possible are discarded. the present work systems derived through a strictly deductive development from principle relativistic invariance, that kind or operator is ruled out only if it causes inconsistencies. As results, new consistent for isolated explic...

Achieving data availability and reliability guarantees against disk failure using redundancy coding scheme. X-code is a double tolerant to achieve the optimal update complexity. It reduces the possibility of data unavailability when disk/node fails. X-code based optimal recovery scheme Minimum-disk-read-recovery (MDRR) and Group-based MDRR (GMDRR) minimizes the number of disk reads for a single...

As applications of secure multicast in networks continue to grow, the demand for an efficient scheme to manage group keys for secure group communication becomes more urgent. In this paper, we propose a new key tree structure for group key management. With this optimal tree structure, system resources such as network bandwidth can be saved. We devise an algorithm to generate this optimal tree an...

Juels, Catalano, and Jakobsson (JCJ) proposed at WPES 2005 the first scheme that considers real-world threats and that is more realistic for remote elections. Their scheme, though, has quadratic work factor and thereby is not efficient for large scale elections. Based on the work of JCJ, Smith proposed an efficient scheme that has linear work factor. In this paper we first show that the Smith’s...
