Abstract

The goal of intrusion detection systems(IDS) is to protect from the signs of security problems. However, since an IDS usually depends on the monitored data and has to identify an intruder, the running of IDS comes to threaten users' privacy. In this paper, we propose a new privacy preserving method in intrusion detection system by applying cryptographic methods to log files. It can meet the enhanced privacy of users as well as the security of network providers without TTP.
