Multi-Sender Multi-Receiver Authentication for Dynamic Secure Group Communication

This paper proposes an Intrusion Detection System (IDS) architecture which can detect and respond against the generation of abnormal traffic such as malicious code and Internet worms. The model the system, design and implement a simulator using OPNET Modeller, for the performance analysis on the response capacity of alert information in the proposed system. At first, its model the arrival process of alert information resulted from abnormal traffic. In order to model the situation in which alert information is intensively produced, it applied the IBP (Interrupted Bernoulli Process) which may represent well the burstiness of traffic.
