Resource Requirement Analysis for a Predictive-Hashing Based Multicast Authentication Protocol

摘要

A new multicast authentication scheme for real-time streaming applications was proposed that is resistant to denial-of-service attacks with less resource usages (CPU and buffer) at receivers compared to previously proposed schemes. This scheme utilizes prediction hashing (PH) and one-way key chain (OKC) techniques based on erasure codes and distillation codes. Detailed protocol description is presented at the sender and receiver sides, and a worst-case resource (memory and CPU) requirement at the receiver-side is obtained with an assumption of security condition.
