Description of the research topic:
"In 2020, the Internet of Things (IoT) no longer means just ""linked sensor objects."" It has evolved from simple devices that capture data to devices, which connect the physical and digital worlds, make sense of what is happening, and take actions that benefit the physical world. Today, IoT devices are small, cheap, robust, and widespread – according to estimations [1], there will be 74 billion connected devices by 2025.
Internet of Things is a promising research area due to its embedded technology. From smart homes and wearables to biochips and health monitors – all these innovations are the impact of IoT. This approach has led to many innovative ideas that reduced the work of a human but increased security risks. Though IoT security progressed in the last few years, yet there are many unsolved problems, which need to be researched.
The TLS and SSL protocols are the de-facto standards for secure Internet communications. The extra energy cost of encrypting and authenticating the application data with SSL is around 15%. For IoT devices, where energy resources are limited, the increase in energy consumption is a very significant factor. The research in this topic covers energy-efficient security protocols that ensure maximum bandwidth and the required level of security with minimum energy consumption. The goal is to save energy needed for data encryption and, at the same time, to provide an appropriate security level for IoT devices. In February 2019, ETSI Technical Committee on Cybersecurity (TC CYBER) announced a global standard, ETSI TS 103 645 [2], cybersecurity for IoT. The standard establishes a security baseline for consumer IoT products and provides a basis for future IoT certification schemes.
A Ph.D. student can work in this field to create new grounds in IoT security and energy efficiency. Possible research topics include (and are not limited to) secure and energy-efficient data routing techniques; cybersecurity in 5G networks; secure channel establishment algorithms for the isolation of misdirection attack; secure authentication methods; the clock synchronization methods for IoT devices; energy-efficient data communication, etc.
