摘　　要：针对信息中心移动自组网场景中节点间间歇连接和网内泛在缓存的特点,提出一种基于门限秘密共享机制的数据访问控制机制.通过构建辅助密钥块,降低了消费者解密的开销和网络节点的存储资源消耗.同时,通过引入双变量单向函数,保障了消费者子秘密份额的唯一性,减少了消费者侧秘密份额管理所带来的空间开销.仿真和理论分析结果表明,该机制显著降低了消费者侧的解密开销,良好地适应了信息中心移动自组织网络场景.Aiming at the characteristics of intermittent connections between nodes and ubiquitous caching in the information-centric mobile Ad hoc networks,a data access control scheme based on threshold secret sharing scheme is proposed. By constructing an auxiliary key block,the consumer’s decryption overhead and the storage resource consumption of network nodes are reduced. At the same time,by combining a two-variable one-way function,the uniqueness of the consumer’s shares is guaranteed,and the cost of key management is decreased. Simulations show that this mechanism dramatically reduces the decryption overhead on the consumer side,which indicates its well suited for information-centric mobile Ad hoc network scenarios.
