Connecting smart cities with Wi-SUN
Summary
With all this influx of residents, cities are facing increasing pressures – for example, to provide services such as water and waste, and to manage traffic and public transport. The huge amounts of data available from various sensors and other sources can enable city planners and managers to make better decisions and to use scarce resources effectively. With hospitals, government agencies, public transport, business organisations and power grids becoming ever more vulnerable to cyberattacks, it’s essential that their networks are secure. A unique feature of Wi-SUN is its native public-key infrastructure (or PKI) integration, certificate-based mutual authentication, and proven data encryption and key exchange algorithms. As smart cities develop over the coming years, Wi-SUN will provide the reliable connectivity needed to balance the priorities of sustainability and quality of life.
