Advanced Communications and Multimedia Security provides a state of the art assessment of present views in addition to the newest advancements within the quarter of communications and multimedia safeguard. It examines standards, matters and strategies pertinent to securing info networks, and identifies destiny security-related examine demanding situations. a large spectrum of issues is mentioned, together with:
-Applied cryptography;
-Biometry;
-Communication platforms safety;
-Applications safety; cellular defense;
-Distributed platforms safeguard;
-Digital watermarking and electronic signatures.

This quantity includes the court cases of the 6th Joint operating convention on Communications and Multimedia defense (CMS'02), which used to be subsidized via the foreign Federation for info Processing (IFIP) and held in September 2002 in Portoroz, Slovenia. It constitutes crucial studying for info safety experts, researchers and pros operating within the quarter of laptop technology and verbal exchange systems.

Sample text

Thus a malicious merchant could spread himself the copy sold to some buyer and then accuse that buyer of having done so. And on the other hand, a buyer whose fingerprint has been found in the redistributed copy could claim that it is the owner who wants to frame her that redistributed the copy with her fingerprint deliberately. In order to solve this problem, Pfitzmann and Schunter proposed the concept of asymmetric fingerprinting in [PS96]. The above problem is solved in the following way: After a sale, only the buyer knows the copy with the fingerprint.

The actual group for the calculation is determined by a set of so called domain parameters. It consists of the following items. • The field size, which defines the underlying field Fq • In case of binary fields the used basis type and in case of a polynomial base representation the irreducible polynomial, is required. • The Curve Parameters a and b E Fq • The Base Point G = (xa,Ya), xa,Ya E Fq on E of prime order. • The Order n (of the base point G). • The cofactor h = #E(Fq)/n • Optional parameters.
