“…The computation cost of FN verification compared with other schemes is shown in Figure 4. We can see that neither [24,25] nor our scheme involves bilinear mapping operations, resulting in higher execution efficiency compared to [27,28]. With the increase in the number of charging and discharging EVs, the computation overhead of the FN becomes lower and lower compared with other schemes.…”

“…Table 5 compares the signcryption output length as the communication cost with other schemes. It can be seen that our scheme and [24] have the lowest communication overhead, both of which are 640 bits. Compared with [27], our scheme is reduced by (2208 − 640)/2208 = 71.01%; compared with [28], it is reduced by (4416 − 640)/4416 = 85.51%; compared with [25], it is reduced by (960 − 640)/960 = 33.33%.…”

“…Taking the example of m FNs, where each fog node region contains n EVs, we analyze the computational and communication overheads of the proposed scheme. Furthermore, we also compare our scheme with other related CLASC schemes (i.e., Basudan et al [27], Wang et al [28], Dai et al [24], and Zhang et al [25]). The first two schemes are based on fog computing architecture, while the latter two are based on traditional architecture.…”

Due to the openness of the vehicle-to-grid (V2G) network, the upload of charging and discharging data faces severe security challenges such as eavesdropping, tampering, and forgery. These challenges can lead to privacy breaches, transmission delays, and service quality degradation. To address these issues, a V2G network architecture based on cloud–fog-end is designed, and a charging and discharging data privacy protection scheme is proposed. We employ a pseudonym mechanism to achieve the conditional privacy protection of electric vehicle (EV) users. We design a certificateless aggregate signcryption (CLASC) algorithm to guarantee the security of uploading the charging and discharging privacy data. The algorithm solves certificate management and key escrow issues, utilizes aggregate signature operations to save network bandwidth, and avoids complex computations like bilinear pairings and exponents. Additionally, the scheme delegates the aggregate verification process to the fog layer, thereby alleviating the computational burden on the cloud layer, decreasing transmission delays, and enhancing the efficiency and reliability of the V2G network. The analysis results indicate that the scheme not only meets the required security objectives, but also has lower computational and communication overheads, making it suitable for scenarios involving the charging and discharging of large-scale EVs in V2G networks.

With the rapid increase in smart grid users and the increasing cost of user data transmission, proposing an encryption method that does not increase the construction cost while increasing the user ceiling has become the focus of many scholars. At the same time, the increase in users will also lead to more security problems, and it is also necessary to solve the privacy protection for users during information transmission. In order to solve the above problems, this paper proposes an aggregated ring encryption scheme based on the SM2 algorithm with special features, referred to as SM2-CLARSC, based on the certificateless ring signcryption mechanism and combining with the aggregate signcryption. SM2-CLARSC is designed to satisfy the basic needs of the smart grid, and it can be resistant to replay attacks, forward security and backward security, etc. It has better security and higher efficiency than existing solutions. Comparing SM2-CLARSC with existing typical solutions through simulation, the result proves that this solution has more comprehensive functions, higher security, and significant computational efficiency improvement.
