| 摘 要： | STR组密钥管理协议因采用非平衡二叉树结构使得密钥更新过程简化,它可以有效降低组密钥管理的通信开销,但这是以高额的计算开销为代价的.提出一种基于STR非平衡密钥树结构的混合分层组密钥管理方案,在继承STR协议低通信开销的特点的同时,该方案显著降低了组密钥管理的计算开销并提高了密钥更新效率.

| 关 键 词： | 组密钥管理 密钥更新效率 计算开销 通信开销 安全 |

| Abstract: | STR group key management protocol can simplify key updating for its unbalanced binary-tree structure and decrease communication cost by increasing computing cost in group key management.A hybrid group key management scheme based on STR unbalanced tree was presented.It significantly decreases computation cost,and increases key updating efficiency,while maintaining the low-communication cost feature of STR protocol at the same time. |

| Keywords: | group key management key updating efficiency computing cost communication cost security |
