Title: Cybersecurity in Quantum Era
Abstract: Current asymmetric key cryptography based on well-known and mostly used computational problems is expected to be broken by a large-scale quantum computer in the next one or two decades. The NIST completed the third round of the Post-Quantum Cryptography standardization process in July 2022 and will continue into the fourth round. There is also another approach that is not based on mathematical algorithms but on quantum physics principles, which is Quantum Key Distribution (QKD). The QKD technology employs physical laws to establish cryptographic keys between two parties. The QKD link consists of two channels: a unidirectional quantum channel for the transmission of cryptographic keys encoded into quantum states of photons, and a bidirectional public channel for post-processing procedures. The technology cannot prevent the link from eavesdropping but it can detect it.
Miroslav VOZNAK (IEEE Senior Member) received his Ph.D. in telecommunications from the Faculty of Electrical Engineering and Computer Science, VSB-Technical University of Ostrava, in 2002, and achieved habilitation in 2009. He was appointed Full Professor in Electronics and Communications Technologies in 2017. His research interests generally focus on information and communication technologies, especially on the quality of service and experience, network security, wireless networks, and big data analytics. He has authored and co-authored over one hundred articles indexed in SCI/SCIE journals. According to the Stanford University ranking released in 2020 and also in 2021, he is one of the World’s Top 2% of scientists in Networking & Telecommunications.
