Education

Bio

Stanislaw Radziszowski is a Professor in the Department of Computer Science since 1995. He earned Ph.D. from the Institute of Informatics at the University of Warsaw. During the years 1980-1984 he worked in IIMAS at the National Autonomous University of Mexico in Mexico City, and since 1984 at the RIT. In the 1990's he held three times 6-week visiting positions at the Australian National University in Canberra, and maintained collaborations with universities in Poland.

His main research interest is in combinatorial computing - solving classical problems in combinatorics, graph theory and design theory, usually with the help of massive computations. Bounds on Ramsey numbers are his favorite. His survey titled 'Small Ramsey Numbers', which is a regularly updated living article at the Electronic Journal of Combinatorics, became a standard reference in this area. He teaches mostly theory oriented courses, including very popular courses on cryptography, both at undergraduate and graduate levels. His recent work on applied cryptography led to joint projects with Computer Engineering Department.

Quantum-Resistant Cryptography (QRC) refers to cryptographic systems that are secure against attacks from both quantum and classical computers. Such systems may be achieved through classical (i.e. non-quantum) means. The security of many commonly used cryptographic protocols (especially Public Key cryptosystems and Digital Signatures) would be compromised if general-purpose, large-scale, fault-tolerant quantum computers became a reality. This course covers the consequences of Quantum Computing and why it poses a threat to currently used cryptographic systems, and then discusses cryptosystems designed to be resistant to such attacks. Students will describe and utilize the designs recommended by NIST for Quantum-Resistant encryption algorithms and explain their security advantages over classical cryptosystems.
