Transactions are commonly described as being ACID: All-or-nothing, Consistent, Isolated and Durable. However, although these words convey a powerful intuition, the ACID properties have never been given a precise semantics in a way that disentangles each pr ...
We propose a straightforward technique to provide peer-to-peer security in mobile networks. We show that far from being a hurdle, mobility can be exploited to set up security associations among users. We leverage on the temporary vicinity of users, during ...
The spi calculus is an extension of the pi calculus with cryptographic primitives, designed for the verification of cryptographic protocols. Due to the extension, the naive adaptation of labeled bisimulations for the pi calculus is too strong to be useful ...
This thesis is concerned with two security mechanisms: authenticated key transport and rational exchange protocols. These mechanisms are potential building blocks in the security architecture of a range of different services. Authenticated key transport pr ...
The main topic of this thesis is related to the state of the art in designing cryptographic primitives from a hardware point of view. A special emphasis is dedicated to low-power/low-energy CMOS design. A set of solutions is proposed including an LFSR base ...
Obliq is a lexically-scoped, distributed, object-based programming language. In Obliq, the migration of an object is proposed as creating a clone of the object at the target site, whereafter the original object is turned into an alias for the clone. Obliq ...

Cryptographic protocols can enforce privacy in distributed computation of functions [Goldwasser'96] and are a competitor of the distributed constructive search techniques. [Goldreich'87,Chaum'87,Chaum'88,Ben-or'88] show how cryptographic protocols can be c ...

We present three attacks against the authentication protocol that has been proposed for the so called global mobility network in \cite{kn:Suz97}. We show that the attacks are feasible and propose corrections that make the protocol more robust and resistant ...
