A Kind of Security Certification Schema of Hierarchical Distributed Sensor Network Based on Certificate Reconstruction

Abstract:

The characteristics of Wireless Sensor Network (WSN) determine that traditional security certification mechanism can not meet its security needs. Based on introduction of a distributed hierarchical WSN model, the paper divided WSN network architecture into application layer, base station layer and sensor node layer according to difference of computation speed, power energy, communication capability and storage space of sensor nodes. A kind of security certification schema of hierarchical distributed sensor network based on certificate reconstruction was presented. In the schema, application layer and base station layer used common digital certification of PKI model to construct trust relationship. The sensor node achieved identification authentication and data source authentication through certification reconstruction.
