Multidimensional data tight aggregation and fine-grained access control in smart grid

The Challenges of Privacy and Access Control as Key Perspectives for the Future Electric Smart Grid

“…Similarly, a Multidimensional-data Tight Aggregation scheme which supports Privacy-preserving and fine-grained Access control (MTAPA) has been proposed recently by B. Lang et al [121]. MTA-PA is based on Boneh-Goh-Nissim (EBGN) homomorphic encryption scheme and KP-ABE for the access control at the dimension level.…”

Cloud‐assisted secure and conjunctive publish/subscribe service in smart grids

“…It allows the control center to compute several statistical functions of users' electricity usage data in a privacy-preserving form. To protect the consumer privacy in SM data aggregation, Oriero and Rahman [11] designed an anonymous privacy-preserving finegrained data aggregation scheme for AMI networks, Lang et al [10] further extended the scheme to a multidimensional scenario and proposed a multidimensional data tight aggregation scheme which supports privacy-preserving and fine-grained access control (MTA-PA), in which each receiver can only extract the specific dimensions that it has been authorised. However, these methods are all designed for SM data aggregation or analysis operators, in which the fine-grained ACMs mainly focused on fine-grained control of data, not for the data users (e.g.…”

“…However, direct application of these approaches to the P/S service based on huge scale data would not be suitable, as they cannot accommodate the high service-level requirements like system usability and scalability. Although some recent researches have been proposed to support fine-grained access control solutions as an attempt to improve the system scalability [9][10][11], they are mainly designed for data analysis or aggregation, not for P/S service. How to design an efficient encrypted data-based P/S service protocol that supports conjunctive subscriptions under a fine-grained ACM still remains a challenging open problem.…”

Efficient Privacy-Preserving Multi-Dimensional Data Aggregation Scheme in Smart Grid

“…Though the scheme provided two pay-ment modes for SG users, it is not qualified in their data protection. Later, based on BGN homomorphic encryption [38], Bo et al [31] put forward a multi-dimensional data aggregation scheme that employed key-policy attribute-based encryption to enforce fine-grained access control at the dimension level. Furthermore, a fine-grained and fault-tolerant multidimensional data aggregation scheme is proposed by Ge et al [32].…”
