The Research of Distributed Intrusion Detection and Communication Protocol Based on Entity

The existed distributed intrusion detection system adopt the architecture which the data is collected and analyzed centrally, in which there are some defects. The defects are like simple point invalidation and bad extension. On the base of analyzing existed distributed intrusion detection system , this paper designs one distributed intrusion detection system based on the entity model and proposed a secure communication protocol. In order to guarantee security, reliability and integrity among entities in the model, this paper has designed an object- oriented exchange model of information. The paper also has designed a safe transport protocol based on ECC, DES symmetrical and the asymmetrical encryption technology, so it can assure to communicates safely and effectively with each kind of entity.
