Abstract The Pilsung cipher is part of the North Korean Red Star operating system, which was leaked to West in 2014. Initial analysis by Kryptos Logic reported a possibility class weak keys due use pseudo-random diffusion. Following this lead, we analyzed and identified small such keys. We developed techniques for searching key that belongs class. After spending thousands CPU hours, found suppo...

We present a row-by-row (RBR) method for solving semidefinite programming (SDP) problem based on solving a sequence of problems obtained by restricting the n-dimensional positive semidefinite constraint on the matrix X. By fixing any (n − 1)-dimensional principal submatrix of X and using its (generalized) Schur complement, the positive semidefinite constraint is reduced to a simple second-order...

In this paper, a systematic analysis for memory usage in H.264/AVC scalable extension (SVC) decoder is presented. This paper analyzes the memory requirements with three different decoding flows, macroblock, row and frame based, to find out a best method which can achieve optimal trade-off between internal memory usage and external memory access. The analysis shows that the SVC decoding needs 88...
