Intelligent agents in support of internet security

Internet today is the main medium rapidly delivering information that we need. Theinformation is delivered via a vast number of services that make our life become faster and moreconscious. The question is at what price? The solutions devised by humans are prone to errors,which furthermore entail a new type of security challenge – cyber crime. With this paper we try toshow that autonomous intelligent agent based systems are able to support or even offload humansin bringing Internet Security to the next level. The related research is focused on analyzingnetwork information flows, building knowledge base and applying reasoning techniques thatwould allow agents to track suspicious network activities, identify and profile users and finallyindicate and prevent cyber crime. The main applications for this solution are forensics and lawenforcement support

Group signature revocable anonymity scheme for network monitoring

Subscriber’s Privacy is in a constant conflict with security and accountability providing controls employed for network monitoring activities of service providers and enterprises. This paper presents the results of the author’s research in the field of distributed network security monitoring architectures and the proposal of such a system that incorporates cryptographic protocols and a group signature scheme to deliver privacy protecting, network surveillance system architecture that provides subscriber’s accountability and controlled, revocable anonymity
