Abstract

We report on a work in progress that aims to develop a secure and efficient method for key exchange in wireless sensor networks. The keys exchanged will then be used for secure communication between sensors. The sensor nodes must maintain battery life for long periods of time while still providing full functionality. One way to extend battery life is to reduce CPU usage of the sensors. The proposed method to reduce CPU usage is to implement a matrix based key exchange algorithm. Currently many sensors use a public key exchange which requires heavy exponentiation. The matrix based key exchange does not require exponentiation and will therefore extend battery life. The project currently is in the predeployment stage which involves establishing a symmetric matrix as a product of two other matrices. Once the matrices are established and assigned, simulations will be run to determine CPU usage and be compared to that of a public key exchange. Simulating the key exchange prior to deployment will help in determining the efficiency of the algorithm and will be compared to public key exchange. Deploying sensors containing the algorithm will be the final step in the implementation. If the matrix based key exchange is more energy efficient than a public key exchange, it can be used as an alternative method within wireless sensor networks. Using a more efficient algorithm will save energy spent on CPU capabilities and still provide the essential encryption.
