Overview of identifyer-based encryption method (Image from the original paper)

For the secure two-way communication and forwarding, this paper proposes SRDA, a secure routing and data aggregation approach for wireless smart meter. This approach introduces the unique wireless smart meter identifier to represent its public identity information, and gives a secure routing architecture based on control and forwarding separation. In this architecture, SRDA uses the proxy re-encryption data aggregation algorithm to protect security of data transmission. By using the routing algorithm according to distance and link quality, SRDA achieves the best routing path and provides several alternative paths which have different priorities. Besides, the identifier-based cryptography mechanism is used to issue and update the routing information in security, and the proxy re-encryption mechanism is designed to preserve the data privacy. In conclusion, this paper gives an analysis for the relatively excellent security, scalability and energy efficiency.
