Security Authentication through AES and fine-grained distributed Data Access Control using clustering in Wireless Sensor Networks

Wireless Sensor Networks have been a significant area in the research of Security Authentication and the Data Access Control. This paper presents a distributed data access control scheme fine-grained access control over sensor data which is resistant against strong attacks such as sensor compromise and user colluding. Here a new security mechanism proposed in the defined clustering schema which includes base station, cluster heads and the sensor nodes. Here the data are transmitted using the cluster head instead of direct transmission from individual sensor nodes to the base station and thus, the energy conserved for the sensor nodes are much reduced which paves the way for long time data transmission. Distributed Cluster Heads and Base station are designed using the NS2 Simulation Environment. The proposed scheme exploits an Advanced Encryption Standard (AES) with CCMP (CBC-MAC), which improvises, adapts and stabilizes the WSNs with respect to both performance and security requirements. This paper gives insight and improvement to realize distributed fine-grained data access control in clustered environment & the symmetric encrypted procedures using AES with CCMP.
