On Privacy Losses in the Trusted Agent Model (Abstract)

Tamper-proof devices are pretty powerful. They typically make security applications simpler (provided that the tamper-proof assumption is not violated). For application requiring privacy, we observe that some properties may become harder (if possible at al ...

On Tamper-Resistance from a Theoretical Viewpoint: The Power of Seals

Serge Vaudenay

Tamper-proof devices are pretty powerful. They can be used to have better security in applications. In this work we observe that they can also be maliciously used in order to defeat some common privacy protection mechanisms. We propose the theoretical mode ...

Authentication of secure items by shape level lines

Roger Hersch, Sylvain Chosson

The disclosed method and system may be used for creating advanced protection means for various categories of documents (e.g. bank notes, identity documents, certificates, checks, diploma, travel documents, tickets) and valuable products (e.g. optical disks ...

Precoding for broadcasting with linear network codes

Ali H. Sayed

A technique based on linear precoding is introduced for broadcasting on linear networks. The precoding allows the different message components of a broadcast message to be separated and decoded at the desired sink nodes, thus providing a systematic design ...

Fair Exchange with Guardian Angels

Serge Vaudenay, Gildas Avoine

In this paper we propose a new probabilistic Fair Exchange Protocol which requires no central Trusted Third Party. Instead, it relies on a virtually distributed and decentralized Trusted Third Party which is formalized as a Guardian Angel: a kind of Observ ...

Introducing Trusted Third Parties to the Mobile Agent Paradigm

Uwe Wilhelm

Systems that support mobile agents are increasingly being used on the global Internet. An important application that is considered for these agents is electronic commerce, where agents roam the World Wide Web in search of goods for their owners. In these a ...

On the Problem of Trust in Mobile Agent Systems

Levente Buttyan, Uwe Wilhelm

Systems that support mobile agents are increasingly being used on the global Internet. Security concerns dealing with the protection of the execution environment from malicious agents are extensively being tackled. We concentrate on the reverse problem, na ...

Recursive solutions of rational interpolation problems via fast matrix factorization

Ali H. Sayed

We describe a novel approach to analytic rational interpolation problems of the Hermite-Fejér type, based on the fast generalized Schur algorithm for the recursive triangular factorization of structured matrices. We use the interpolation data to construct ...
