ABSTRACT

CRYPTO-PKI

This part summarizes main research gaps regarding cryptographic protocols as well as key distribution and management schemes in order to ensure appropriate levels of security in future technologies. In particular, due to the massive deployment of low-end devices, either in the form of ‘smart’ Internet-of-Things technology or as sensors to make up Industry 4.0 infrastructure, a new class of lightweight crypto primitives is required. They must adhere to new requirements such as low energy consumption, minimal hardware footprint and easy synthetization in hardware. Securing vastly deployed devices is of utmost importance as they are considered as the building blocks of upcoming technological trends such as smart city, car-to-X scenarios and more. Furthermore, technologies to distribute and manage cryptographic keys in a way that allows for efficient scaling and preserves the security of the overall system are required for secure interaction with distributed devices. Lastly, those schemes and cryptographic primitives must provide sufficient usability for the end-user and further must remain resilient against attacks in the future. Thus, post-quantum secure encryption and authentication schemes must be considered.
