A smart grid is a new ecosystem, which is made by combining a number of smart Internet of Things (IoT) devices that manage wide energy sources by increasing the efficiency and reliability of the smart energy systems. As the IoT devices in the smart grid ecosystem generate a gigantic amount of data that needs to be stored and managed in the cloud server. On the other hand, the stored data in the cloud server can be accessible to a number of data users, therefore the data need authenticity and secrecy. Here, to fulfill the security requirements of such type of communication, signcryption with proxy re-encryption technique is the most suitable option where a semi-trusted third party can alter a ciphertext that has been encrypted for one user into another ciphertext without seeing the original content of the message. However, the existing signcryption with proxy re-encryption schemes for the smart grid environment is suffering from more bandwidth space and greater computational time requirements. Thus, in this paper, we propose a lightweight certificate-based signcryption with a proxy re-encryption (CBSRE) scheme for smart grid based-IoT devices with the intention of reducing the computational and communicational costs. For the security and efficiency of the proposed CBSRE scheme, we used a hyperelliptic curve cryptosystem that uses small parameters with a key size of 80-bits. Furthermore, the proposed scheme provides the security requirements of confidentiality (IND-CBSRE-CCA2-I and IND-CBSRE-CCA2-II), unforgeability (EUF-CBSRE-CMA-I and EUF-CBSRE-CMA-II) and forward secrecy. Additionally, we compared our proposed CBSRE scheme with the existing proxy signcryption with re-encryption schemes and the final results show that the new scheme provides strong security with the expanse of minimal computational and communications resources.

“…In EPPDC, we assume that the SM's signature can be converted into the same as the existing literatures such as [7][8][9][10][11] using bilinear pairing, which can also perform the bath verification [7]. So here we mainly discuss the computation complexity of messages turning to , the signature of BGW, verification of BGW's signature, and recovery for the original message .…”

“…And existing homomorphic encryption to achieve privacy preserving is based on the computational expensive operations [7,9], which may not be desirable for smart grids with limited resources in terms of both bandwidth and computation. And the existing signcryption based schemes in smart grid [10,11] cannot meet forward secrecy. This paper proposes an efficient privacy-preserving data collection scheme for smart grid, which is based on the blind signature and the key distribution scheme.…”

“…The proposed privacy-preserving schemes about smart grid are mainly constructed by two kinds of cryptographic tools, homomorphic encryption [7][8][9] and signcryption [10,11]. By homomorphic encryption, smart meters (SMs) encrypt the messages and send them to gateway (BGW), but gateway cannot get any users' messages without the system private key.…”

Different from the traditional grid, smart grid builds a real-time connection network between the user and the grid company by smart terminals, which can achieve bidirectional data transmission and information control. In smart grid, the smart meters send various information to the power generators and substations. Frequent data collection meets real-time management, but it tends to raise privacy concerns from the users about privacy information leakage. Based on the blind signature and the key distribution scheme, an efficient and privacy-preserving data collection (EPPDC) scheme is proposed for smart grid to cope with the above problems. In EPPDC scheme, the users' data information is transmitted to the local aggregator by building gateway with privacy preserving. In addition, the security analysis indicates that EPPDC scheme not only can resist replay attack, but also has source authentication and data integrity, confidentiality, unforgeability, nonrepudiation, and evolution of shared keys. Furthermore, performance analysis shows that EPPDC scheme has less computation cost than existing scheme.
