Restricted access - publisher's policyCodes with the Identifiable Parent Property (IPP codes) form a very useful tool in traitor tracing schemes since they guarantee (with probability 1) identification of at least one of the traitors. We consider a natural ...

Restricted access - publisher's policyThe theory of separating codes has been applied in several areas of science ranging from automata synthesis to the protection of distribution rights. In this paper, we introduce a relaxed version of separating and secure ...

Open AccessIn this paper we discuss some variations of the notion of separating code for alphabets of arbitrary size. We show how the original definition can be relaxed in two different ways, namely almost separating and almost secure ...

Restricted access - publisher's policySecure frameproof code is the name given to a separating code when studied in relation to fingerprinting schemes. Separating codes are combinatorial objects that have found to be useful in many areas such as technical ...

Open AccessA traceability or fingerprinting scheme is a cryptographic scheme that facilitates the identification of the source of leaked information. In a fingerprinting setting, a distributor delivers copies of a given content to a ...
Parallelization of the interpolation process in the Koetter-Vardy soft-decision list decoding algorithm Moreira Sánchez, José; Fernández Muñoz, Marcel; Soriano Ibáñez, Miguel (2012)
Open AccessList decoding is a decoding strategy that provides a set of codewords at the output of the channel decoder. Since this technique corrects errors beyond the correcting bound of the code, upper layers in the application or ...

Open AccessThe concept of data fingerprinting is of paramount importance in the framework of digital content distribution. This project deals with fingerprinting codes, which are used to prevent dishonest users from redistributing ...
