摘要

In this paper, we present an access control scheme for PIM-SM multicast domain. In order to avoid the overhead of digital signature algorithm, the proposed solution makes use of the Rendezvous Point to collect keys and implement a distributed shared-key based multicast access control system. As it supplies efficient host access control in PIM-SM domain, we name this scheme PIMac. Compared with the existing multicast admission control solutions, PIMac has following advantages: (1) support both receiver and sender access control; (2) realize host exclusion based on expire time; (3) compatibility with current PIM-SM protocol; (4) lower join latency; (5) anti-replay and DoS robustness; last but not least, (6) PIMac architecture is divided into two separated domains: AAA domain and multicast routing domain, entities in each domain do not rely on PKI interoperability or common secret to authenticate each other. The experimental results show that PIMac achieves flexible manageability and improves the performance of multicast access control systems effectively.
