Security and privacy in the smart grid services

The paper focuses on the usability of privacy-enhancing cryptographic protocols and primitives for secure smart grid services. The paper introduces a security solution that is suitable for secure smart grid services providing the privacy protection of user during the data collection process. Our cryptographic solution is designed to ensure privacy protection, data authenticity, confidentiality and data integrity in heterogeneous smart grid networks which contain smart meters, embedded devices and smart grid appliances. Our solution uses lightweight cryptography to secure communication from constrained smart meters and provides privacy protection by using the group signatures that enable service providers to collect anonymized user data.
