Based on the U2IoT model, this paper proposes a cyber-physical-social based security architecture (IPM) to deal with Information, Physical, and Management security perspectives, and presents how the architectural abstractions support U2IoT model. In particular, 1) an information security model is established to describe the mapping relations among U2IoT, security layer, and security requirement, in which social layer and additional intelligence and compatibility properties are infused into IPM;2) physical security referring to the external context and inherent infrastructure are inspired by artificial immune algorithms;3) recommended security strategies are suggested for social management control. The proposed IPM combining the cyber world, physical world and human social provides constructive proposal towards the future IoT security and privacy protection.展开更多

Membranaceus Munro) andtheir physical and mechanical properties have been studied in the paper. The results showed that the whangee hasbetter physical properties than that of the Yunnanicus, such as higher density, lower tangential and longitudinal dryshrinkages. That also showed that Whangee has stronger mechanical properties in MOR and MOE, compressivestrength and shear strength parallel to the grain. Compared with some wood species used in architecture, the physicaland mechanical properties of the two kinds have reached the requirement of some wood architecture structurematerials.展开更多
