Blockchain-enhanced SDN framework with deep unfolding spatial frequency attention network and pine cone optimization for smart city IoT cybersecurity
This paper proposes a new cybersecurity framework for smart city IoT networks using blockchain, deep learning, and optimization algorithms. The system, named DUSFAN-PCO, aims to detect network anomalies and securely store data to prevent cyberattacks.
Why it matters
As smart cities become more interconnected, robust cybersecurity frameworks are essential to protect critical infrastructure from increasingly sophisticated digital threats.
