In this paper we present a software architecture and a development environment for the implementation of applications based on secure mobile agents. Recent breakthroughs in mobile agent security have unblocked this technology, but there is still one important issue to overcome: the complexity of programming applications using these security solutions. Our(More)
We present in this paper a decentralized architecture to correlate alerts between cooperative nodes in a secure multicast infrastructure. The purpose of this architecture is to detect and prevent the use of network resources to perform coordinated attacks against third party networks. By means of a cooperative scheme based on message passing, the different(More)
This paper presents a protocol for the protection of mobile agents against external replay attacks. This kind of attacks are performed by malicious platforms when dispatching an agent multiple times to a remote host, thus making it reexecute part of its itinerary. Current proposals aiming to address this problem are based on storing agent identifiers, or(More)
A general trust model and security framework for a multi- agent system designed to manage resources in future mobile communications networks is described. The multi- agent system is being developed as part of the IST SHUFFLE project [1]. A business model appropriate for selling of bandwidth resource and services is investigated and mechanisms to achieve a(More)
