John D. Villasenor,Jiangtao Wenanisms. This paper describes an architecture of MobInfoSec system for sharing documents with sensitive information using fine-grained access rules described by general access structures. However, the proper usage of general access structures requires trusted components and strong authentication prot

Thad B. Welch,Michael J. Walker,Ray A. Foranber of independent constraints connected with: dynamic changes of the environment, security assumptions, network limitations and end-users personal requirements, the context factors need specific treatment to be real support for an optimal route selection. The proposed framework systemizes the roles

Encrypting Huffman-Encoded Data by Substituting Pairs of Code Words without Changing the Bit Count ir-by-pair, in such a way that the sums of the code word lengths of an original pair and its substitute are equal. Thus our method preserves structures and lengths of bit streams that result from the Huffman encoding. This is advantageous if such a bit stream is embedded in a higher-level data conta

Statistical Analysis of the Chaos-Driven Elliptic Curve Pseudo-random Number Generators,ptic curves over finite fields of prime order, we propose a method of generating such sequences of points with algorithms driven by a chaotic map. Our construction improves randomness of the sequence generated since it combines good statistical properties of an ECPRNG (Elliptic Curve Pseudo-Random N
