A Novel Batch Rekeying Processor Architecture for Secure Multicast Key Management

摘要

The performance of secure multicast is based on an efficient group rekeying strategy which ensures that only authorized members have access to the content. In this paper a HW-solution for group rekeying is proposed. Besides the high performance guaranteed by pipelining and dynamic tree management, the Batch Rekeying Processor enables two modes of operation: real-time and batch rekeying. In addition, our solution uses a new strategy to keep the loss of QoS and access control caused by batching within system-specific limits.
