A secure and efficient anonymous certificateless signcryption for Key Distribution Scheme for Smart Grid

Smart Grid uses modern metering electricity and some devices that collect energy data in a real time manner and send the clients usage report of electricity usage to the service provider. The service provider uses the received data for billing the client or other services. Through this smart grid, the daily energy consumption and devices that are being used by home owner can be predicted by the service provider depending on how electricity is consumed. This can lead to security issues security where hackers can easily capture clients data while it's being transferred to the service provider. The hacker can modify the transmitted data and the services provider will receive the wrong data. This paper introduces a key distribution system that is more efficient and secure. Existing identity based encryption and identity based signature schemes for smart grid have key escrow problem. In this paper we introduce a certificateless signcryption for key distribution scheme which is more efficient and secure than the existing schemes. It allows for both decryption and verification by authorized users, provide Key Generation Center to only partial key and provide low computation and communication cost compared with existing works. The proposed scheme also achieves key escrow resilience unlike previous works in this field.
