Enhancing Data Security in WSN using Symmetric Key Algorithm

Free registration required

Executive Summary

Data aggregation is implemented in wireless sensor networks to reduce data redundancy and to summarize relevant and necessary information without requiring all pieces of the data and to reduce large amount of data transmission. Homomorphic public encryption is the proposed scheme designed for multi-application environment. The base station extracts application-specific data from aggregated cipher texts, and compromised attacks in single application environments, and to degrade damage from unauthorized aggregations. To enhancing a new approach as symmetric key algorithm used where the keys for encryption and decryption are done in same shared secret.
