摘要: 利用Hash函数和二元单向函数,通过构造两个特殊的多项式,提出一种新的组播密钥管理方案—基于哈希函数的组播密钥管理(HFMKM)方案。此方案整合了集中式与分布式的特性,克服了传统集中式平面型管理方式的安全性完全依赖于组管理者的弊端。将其与GKMP方案进行了比较和分析。结果表明,HFMKM方案安全性明显提高,并提升了整体性能,是一种安全的新型组播密钥管理方案。

Abstract: By constructing two special polynomials,a new multicast key management (MKM) scheme-Hash Function-based Multicast Kcy Management (HFMKM) scheme was proposed,which was based on hash function and two-variable one-way function. The properties of both centralized and distributed were combined in this scheme, so it overcame the defect of conventional centralized flat schemes, whose security totally depended on the Group Controller CGC). With Comparing and analyzing it with GKMP scheme, the results showed that the HFMKM scheme obviously improved the security and the overall performance. It is a new security MKM scheme.

Key words: Hash function, Two-variable one-way function, Key management, Secure group communication, Forward confidentiality, Backward confidentiality
