: Designing security-critical systems correctly is very difficult. We present work on software engineering of security critical systems, supported by the CASE tool AUTOFOCUS. Secur...
A multi-agent marketplace, MAGNET (Multi AGent Negotiation Testbed), is a promising solution to conduct online combinatorial auctions. The trust model of MAGNET is somewhat diffe...
We present a formal analysis technique for probabilistic security properties of peer-to-peer communication systems based on random message routing among members. The behavior of g...
Abstract—In this paper, we propose a distributed key management framework based on group signature to provision privacy in vehicular ad hoc networks (VANETs). Distributed key man...
Abstract: Recently, Au et al. [Au et al. 2007] pointed out a seemingly neglected security concern for certificateless public key encryption (CL-PKE) scheme, where a malicious key g...
