A truly smart city provides solutions that benefit multiple groups, and is not just implemented as a show. The pieces required to have a truly smart City are, smart energy, smart transportation, smart data sharing, smart infrastructure, smart houses and gardens. All of these needs to be able to be configured to work in private, commercial or corporate environments, the configurations, data and policies for each service must be locked and secured at a new level of security.
Smart Cities contain large amounts of Internet of Things (IoT) devices that generate, process, and exchange vast amounts of critical data as well as privacy-sensitive information, and hence are appealing targets of various cyber-attacks.
Many new networkable devices, which constitute the IoT, are low energy and lightweight. These devices must devote most of their available energy and computation to executing core application functionality, making the task of affordably supporting security and privacy quite challenging. Traditional security methods tend to be expensive for IoT in terms of energy consumption and processing overhead.
Moreover, many of the state-of-the-art security frameworks are highly centralized and are thus not necessarily well-suited for Smart cities due to the difficulty of scale, many-to-one nature of the traffic, and single point of failure. To protect user privacy, existing methods often either reveal noisy data or incomplete data, which may potentially hinder some Smart cities applications from offering personalized services. Consequently, Smart Cities demands a lightweight, scalable, and distributed security and privacy safeguard.
Key takeaways:
-- Scalability potential of decentralized networks
-- Data management on Blockchain
-- challenges with decentralize Service control
-- Security ”on the wire” and ”off the wire”
-- Quantum Computer enhanced hacking protection
