by downloading and installing new components dynamically. Dependability and security properties must be preserved under these changes while the user of the BSN must have a transparent view on data usage and installed software. To that end we propose an efficient trust management model and we investigate policies

Trust is considered as a fundamental aspect for interdomain relationships. We have reviewed existing trust models and their drawbacks when they are applied to pervasive environments. We present PTM, a new decentralised trust management model for pervasive computing environments. PTM overcomes

A number of recent proposals aim to incorporate security engineering into mainstream software engineering. Yet, capturing trust and security requirements at an organizational level, as opposed to an IT system level, and mapping these into security and trust management policies is still an open

Abstract. The entities participating in a context-aware service platform need to establish and manage trust relationships in order to assert different trust aspects including identity provisioning, privacy enforcement, and context information provisioning. Current trust management models address

Service-oriented Architectures (SOA) facilitate the dynamic and seamless integration of services offered by different service providers which in addition can be located in different trust domains. Especially for business integration scenarios, Federated Identity Management emerged as a possibility

We identify the trust management problem as a distinct and important component of security in network services. Aspects of the trust management problem include formulating security policies and security credentials, determining whether particular sets of credentials satisfy the relevant policies

Trust is considered as a fundamental aspect for inter-domain relationships. We have reviewed existing trust models and their drawbacks when they are applied to per-vasive environments. We present PTM, a new decen-tralised trust management model for pervasive comput-ing environments. PTM overcomes

The widespread use of the Internet signals the need for a better understanding of trust as a basis for secure on-line interaction. In this paper we provide and discuss existing works on trust management models in the area of Multi Agent Systems and highlight the shortcomings. Our proposed model

Peer-to-peer file-sharing networks are currently receiving much attention as a means of sharing and distributing information. However, as recent experience with P2P networks such as Gnutella shows, the anonymous, open nature of these networks offers an almost ideal environment for the spread of self-replicating inauthentic files.
