Authentication and Intrusion Detection System for Mobile Ad-Hoc Networks
|Related article at Pubmed, Scholar Google|
Mobile ad-hoc network is an infrastructure less network. Continuous user authentication is an important prevention-based approach to protect the high security mobile ad-hoc networks (MANETs). Also intrusion detection systems (IDS) are also important in MANET to effectively identify malicious activities. Most previous work studies these two classes of issues separately. In this paper, we propose a framework of combining intrusion detection and continuous authentication in MANETs. In this framework, multimodal biometrics is used for continuous authentication and intrusion detection is modeled as sensors to detect system security state. To obtain the optimal scheme of combining continuous user authentication and IDSs in a distributed manner, we formulate the problem as a partially observable Markov decision process (POMDP) multi-armed bandit problem. We present a structural result method to solve the problem for large networks with number of nodes are used.
