Cyber-Physical-Social Based Security Architecture for Future Internet of Things

Within the emerging paradigm of the Internet of Things (IoT), the U2IoT (Unit IoT and Ubiquitous IoT) model has been presented for the future IoT. Proposes a cyber-physical-social based security architecture (IPM) based on the U2IoT model to deal with information, pysical, and management security perspectives through architectural abstractions. Establishes an information-security model to describe mapping relations among U2IoT, security layer, and security management, in which intelligen e and compatibility properties are infused into IPM. Proposes a physical security model of the external context and inherent infrastructure through artificial immune algorithms. Suggests security strategies for social management control. Reviews main characteristics of U2IoT entities: cyber, physical, social co-existence; connectivity and interactivity; space-time consistency; and multi-identity status. The proposed security architecture (IPM) includes four layers: sensor layer, network layer, application layer, and an additional social layer.
