On Secure Group Admission Control Using ICMetrics

Abstract

The security of a system cannot be certified unless there are formal methods of admission control. Many techniques and protocol have been proposed that try to provide security yet do not focus on the most important question about who has access to the system. When considering group communications it is more important to understand this problem as the security of the system is dependent upon having authorized entities in the group communicating securely. Admission control has previously been studied in distributed systems but repeatedly overlooked in security. In this paper we provide a polling centred admission control system based on ICMetrics. We choose the polling based system as it considers the opinion of current group members when giving access to members wishing to join the group. Our proposed protocol is based on the use of the secure ring signature along with the latest ICMetrics technology.
