In the smart grid, a large number of smart meters distributed at the edge of the network transmit electricity data to the control center through public network. Therefore, it is crucial to authenticate smart meter. Traditional authentication schemes that based on signature are usually rely on the assumption that the private key is absolutely secure, and private key exposure will endanger the security of the whole scheme. Further, most of these schemes are designed with bilinear pairings, which results in a high cost in computation and communication. So, an efficient revocable ID-based key insulated signature scheme is proposed in this paper. Computational analysis shows that our scheme has less cost than other schemes in computation and communication, which is suitable for smart meters with limited computational capability. Besides, our scheme can revoke the misbehaving or malicious smart meter conveniently and quickly.
