Security observance throughout the life-cycle of embedded systems

Arjen Lenstra

Embedded systems are an established part of life. Their security requirements underline the importance of properly formulated, implemented, and enforced security policies throughout their life-cycle. Currently, security is just an afterthought, and most so ...

Toward Quantifying System Manageability

George Candea

Manageability directly influences a system's reliability, availability, security, and safety, thus being a key ingredient of system dependability. Alas, we do not have today a good way to measure manageability or reason quantitatively about it, and this is ...

Security in distributed metadata catalogues

Nuno Filipe de Sousa Santos

Catalogue services provide the discovery and location mechanisms that allow users and applications to locate data on Grids. Replication is a highly desirable feature in these services, since it provides the scalability and reliability required on large dat ...

Architecture for Secure and Private Vehicular Communications

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Maxime Raya, Levente Buttyan

The deployment of vehicular communication (VC) systems is strongly dependent on their security and privacy features. In this paper, we propose a security architecture for VC. The primary objectives of the architecture include the management of identities a ...

A model for the design of effective and resilient supply chain security management systems

Ximena Gutiérrez Rueda

The current business environment has become more risky and variable. In particular, the recent terrorist attacks against western economies have revealed the vulnerability of global supply chains. These events showed that companies that move cargo internati ...

Efficient and Robust Pseudonymous Authentication in VANET

Jean-Pierre Hubaux, Panagiotis Papadimitratos

Effective and robust operations, as well as security and privacy are critical for the deployment of vehicular ad hoc networks (VANETs). Efficient and easy- to-manage security and privacy-enhancing mechanisms are essential for the wide-spread adoption of th ...

Security Aspects of Inter-Vehicle Communications

Jean-Pierre Hubaux, Maxime Raya

Inter-Vehicular Communications (IVC) are a cornerstone of the future intelligent transportation systems. A crucial enabling component of IVC is its security and privacy. Indeed, as vehicular computing systems become interconnected, there will be new venues ...

Optimal location of FACTS devices to enhance power system security

Stéphane Gerbex

This paper compares three heuristic methods (SA, TS and GA) applied to the optimal location of FACTS devices in a power system. The optimizations are made on three parameters: the location of the devices, their types and their sizes. The FACTS devices are ...

Beyond "Web of Trust": Enabling P2P E-commerce

Karl Aberer, Manfred Hauswirth, Anwitaman Datta

The huge success of eBay has proven the demand for customer-to-customer (C2C) electronic commerce. eBay is a centralized infrastructure with all its scalability problems (network bandwidth, server load, availability, etc.). In this paper we argue that C2C ...

Mobility Helps Security in Ad Hoc Networks

Jean-Pierre Hubaux, Levente Buttyan, Srdan Capkun

Contrary to the common belief that mobility makes security more difficult to achieve, we show that node mobility can, in fact, be useful to provide security in ad hoc networks. We propose a technique in which security associations between nodes are establi ...
