Authentication of Mobile Business Based on Hierarchical Wireless Sensor Network

The special features of Wireless Sensor Network make the traditional authentication mechanism no longer sufficient for its security requirements. Beginning with the presentation and analysis on current WSN security authentication solution scheme and combing with the widely adopted hierarchy distributed WSN architecture, this work employs the idea of Public Key Infrastructure using digital certificate and brings out an authentication mechanism for hierarchy distributed WSN. We design a certificate structure as well as the identity/data origin authentication mechanism with certificate. The updated certificate scheme and sharing keys have also been provided.
