Abstract: In order to realize an effective access control of sensitive data captured by sensor nodes, researchers have made great achievements on secure and efficient hierarchical access control to satisfy the features of widespread distribution, large universe, limited computation and storage capacity of sensor nodes in ubiquitous sensing network. However, time is the main factor that makes the requirements of hierarchical access control scheme in ubiquitous sensing network different from that in traditional Internet networks, leading to the limited actual application scenario. According to the users' requirement on the nodes for gathering resources, an efficient and secure time-bound hierarchical access control scheme is presented in this paper. Based on the characteristics of perception node in ubiquitous sensing network, including the limited power and computation capability, as well as the storage resource, the scheme optimizes the key storage of user, key derivation time, and public information. The advantages of our scheme include that 1) only one key material is required in each users'access; 2) the balance can be achieved between the time for key acquisition and the amount of public information and 3) the scheme is provably secure without random oracle model. Theoretical analysis indicates that our proposed schedule adapts to user' access control requirement of ubiquitous sensing network.
