| 摘 要： | 源认证是组播安全中的重要问题之一,而有损信道或不可靠传输条件下实时数据流的源认证至今仍是个难题。为此,基于前向散列链数据结构,提出了一种组播源认证方法。该方法采用静态与随机链序列相结合的方式,而且每个数据包至少携带6个前驱包的散列值,保证其认证概率达到90%以上。理论分析表明,该方法完全适用于实时组播流的源认证。

| Abstract: | Source Authentication is one of the most important problems in multicast security,but authenticating real-time data streams over loss channels or unreliable networks is very difficult.A multicast source authentication approach is proposed based on forward hashing chains.The authentication probability can reach 90% because its chaining sequence is both static and random,and every packet contains 6 hashes of its previous packets.The theoretical analysis shows this approach adapts to the source authentication of real-time multicast streams. |
