Journal of Optoelectronics Laser. 41(8): 918-928 (11).1005-0086https://hdl.handle.net/10321/4763With the emergence of modernized power grids into smart equivalents referred to as smart grids (SGs) the bulk generation, transmission, distribution, and end-user infrastructures must be appropriately long-term planned concurrently with the required privacy and security. Notably, the objectives of modern SGs are to minimize power energy losses through theft or physical dissipation. The embedded device-to-device (D2D) communication technology in 5G networks will enable an affordable fail-safe ICT subsystem platform for the SGs. However, Privacy preservation is necessary for D2D services in SGs. In this paper, we propose an anonymity privacy-preserving, and data aggregation scheme. We carry out both security and performance and obtained theoretical analysis and simulation results the privacy algorithm is effective and at the same time, fewer communication overheads are exchanged.11 penOptoelectronics & PhotonicsLightweight encryptionSmart gridNTRU cryptosystemComputational loadCommunication overheadsArticle2023-05-0210050086.2022.08.107
