Abstract : Smart grid is a paradigm shift from the traditional Power grid which promises to make the electric grid both energy efficient and Fault tolerant. Trade-off between Energy savings and Security is a critical issue in Smart grid architecture. Smart grid architecture requires a high level secure data exchanges between sensors like Phasor Measurement Units and Advanced Metering Infrastructures like Smart Meters. In this study a Secure Smart grid Architecture model is proposed for the Smart grid network. Initially DamgardJurik encryption algorithm is applied on the data from the Phasor Measurement Units and a digital signature is then attached to the encrypted text to provide further authentication. The digitally signed data is collected in Data centre where it is decrypted. The proposed architecture has been implemented in both software and hardware. The effectiveness of the system is verified by introducing an intruder in hardware implementation.
