“…In the first set of experiments, we compare a simple aggregation implemented with homomorphic encryption, which would also enable trusted data processing in untrusted infrastructures, with SGX (but without any other components of the proposed architecture), and in pure C, without SGX. The implementation used in the homomorphic encryption aggregation is based on the scheme proposed by Busom et al [8]. The goal is to illustrate how the raw SGX performance compares to a traditional approach that would enable comparable benefits for running protected data analysis in cloud environments, and to an approach that offers no security, but also no overhead.…”

In this paper we propose a data dissemination platform that supports data security and different privacy levels even when the platform and the data are hosted by untrusted infrastructures. The proposed system aims at enabling an application ecosystem that uses off-the-shelf trusted platforms (in this case, Intel SGX), so that users may allow or disallow third parties to access the live data stream with a specific sensitivity-level. Moreover, this approach does not require users to manage the encryption keys directly. Our experiments show that such an approach is indeed practical for medium scale systems, where participants disseminate small volumes of data at a time, such as in smart grids and IoT environments.

“…The datasets between two parties can be compared without compromising the data privacy of the users. Busom et al 60 suggested a homomorphic encryption solution based on Elgamal encryption. The proposal is secure against a coalition composed of a misbehaving substation and some corrupted meters.…”

Security and privacy preservation are important research challenges in Internet of Things (IoT) applications, wherein the information related to customers' habit is seamlessly collected for further analytics. One such IoT application; Smart grid (SG) network uses Information and Communication Technology (ICT) to automate the traditional electricity network between customers and utility companies. In the SG setting, on one side, there is a seamless exchange of energy consumption information, demand change and price change messages between customers and utility grid; on the other side, it offers various cyber security challenges. To avoid some‐one intercepting these messages and modify personal information, it is necessary to communicate these messages using an appropriate security and privacy preservation scheme. The objective of this article is conduct a comprehensive survey on existing security and privacy techniques being developed for the SG network. The survey presented in this article is motivated by the earlier research attempts on cyber security issues in SG, key management techniques, authentication schemes and privacy preservation techniques in SG network. The paper provides a wide review on various authentication techniques till recent developments on lightweight authentication and the privacy preservation techniques including encryption based privacy preservation using homomorphic encryption, elliptic curve cryptography, and lattice cryptography. Furthermore, the article presents our vision on privacy and utility trade‐off issues, privacy enhancement using blockchains, lightweight cryptography, and security challenges in fog node.

“…Hence, appropriate measures have to be taken to preserve clients' privacy in smart metering systems. In this paper, we first analyze a recent proposal by Busom et al (2016) and show how a corrupted substation is able to get the individual reading of any arbitrarily chosen smart meter without requiring the collaboration of any other party. After that, we propose a way to fix the mentioned security flaw which is based on adding an additional step in which the substation proves that it has properly followed all the protocol steps.…”

Smart meters inform the electricity suppliers about the consumption of their clients in short intervals. Fine-grained electricity consumption information is highly sensitive as it has been proven to permit to infer people's habits like, for instance, the time they leave or arrive home. Hence, appropriate measures have to be taken to preserve clients' privacy in smart metering systems. In this paper, we first analyze a recent proposal by Busom et al. (2016) and show how a corrupted substation is able to get the individual reading of any arbitrarily chosen smart meter without requiring the collaboration of any other party. After that, we propose a way to fix the mentioned security flaw which is based on adding an additional step in which the substation proves that it has properly followed all the protocol steps. Our solution is analyzed and shown to be computationally feasible for realistic parameter choices.
