Energy Network

Smart Grid (SG) infrastructure is an energy network connected with computer networks for communication over the internet and intranets. The revolution of SGs has also introduced new avenues of security threats. Although Digital Certificates provide countermeasures, however, one of the issues that exist, is how to efficiently distribute certificate revocation information among Edge devices. The conventional mechanisms, including certificate revocation list (CRL) and online certificate status protocol (OCSP), are subjected to some limitations in energy efficient environments like SG infrastructure. To address the aforementioned challenges, this paper proposes a scheme incorporating the advantages and strengths of the fog computing. The fog node can be used for this purpose with much better resources closer to the edge. Keeping the resources closer to the edge strengthen the security aspect of smart grid networks. Similarly, a fog node can act as an intermediate Certification Authority (CA) (i.e., Fog Node as an Intermediate Certification Authority (FONICA)). Further, the proposed scheme has reduced storage, communication, processing overhead, and latency for certificate verification at edge devices. Furthermore, the proposed scheme reduces the attack surface, even if the attacker becomes a part of the network.

Practical Implications

Purpose – To advise companies of a recent SEC no-action letter relating to tender and exchange offers for certain debt securities. Design/methodology/approach – Reviews various conditions allowing an issuer to use a shortened timeframe in which certain debt tender/exchange offers need be kept open for as few as five business days. Findings – The abbreviated debt tender/exchange offer structure contemplated by the no-action letter provides a more efficient mechanism for conducting debt tender/exchange offers in certain circumstances. Practical implications – Issuers conducting a debt tender/exchange offer should consider whether the new abbreviated structure is more effective in achieving their objectives than the more traditional structures. Originality/value – Practical guidance from experienced securities regulatory lawyers that gives an overview of important developments in debt tender/exchange offer practice.
