Abstract: 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.

Key words: information-centric mobile Ad hoc network, data access control, threshold secret sharing, two-variable one-way function
