Securing Smart Healthcare Cyber Physical Systems

Cyber-physical systems (CPSs) are critical in sectors like healthcare, smart grids, and transportation, making their security against cyber threats, such as blackhole attacks, essential. Current detection methods often fail to distinguish between legitimate and malicious behaviors effectively, leading to insufficient protection. This paper introduces GBG-RPL, a novel approach combining the Gini index and blockchain technology to detect and mitigate blackhole attacks in smart healthcare CPSs. By analyzing data distribution with the Gini index and ensuring data integrity using blockchain, GBG-RPL enhances security and reliability. The proposed solution significantly reduces packet loss, energy consumption, and detection time while improving accuracy and network performance. These results demonstrate its potential to provide a secure and efficient CPS solution. Keywords— smart healthcare system; cyber-physical systems; blackhole attacks; Gini Index; blockchain; trust
