Çetin Kaya Koç

Early Life and Education

Born on 23 January 1957 in Ağrı, Turkey, Çetin Kaya Koç completed his early education in Turkey before earning a B.S. degree in Electrical Engineering, summa cum laude, from İstanbul Technical University. He subsequently pursued graduate study in the United States, receiving his Ph.D. in Electrical and Computer Engineering from the University of California, Santa Barbara in 1988. His doctoral research focused on computer architecture, parallel algorithms, and hardware implementations for algebraic computation.

Academic Career

Following the completion of his doctorate, Koç joined the University of Houston as an assistant professor, a position he held from 1988 to 1992. He then moved to Oregon State University, where he advanced from assistant to full professor over the period 1992 to 2007. During his tenure at Oregon State, he established the Information Security Laboratory, which served as a central research hub for secure hardware and embedded cryptography. Koç subsequently held a faculty position at the University of California, Santa Barbara, from which he has since retired. Throughout his career he maintained international visiting appointments at institutions in Turkey, Italy, and China, including Nanjing University of Aeronautics and Astronautics, supervising doctoral and master's candidates and directing collaborative research programs.

Notable Work and Contributions

In 1999, Koç co-founded the Conference on Cryptographic Hardware and Embedded Systems (CHES) alongside Christof Paar. He served as program co-chair for five consecutive years from 1999 to 2003 and continued to serve on the steering committee, helping establish CHES as one of the premier international venues for research on cryptographic hardware, embedded security, and side-channel analysis.

Koç is recognized as the first researcher to coin and actively use the term "cryptographic engineering," deploying it as the name of a course offered at EPFL, Switzerland annually since 2002, as the title of a book, and as the name of the journal he founded. He provided a detailed definition and history of the field in a 2011 article entitled "Introduction to Cryptographic Engineering." He also founded and served as Editor-in-Chief of the Journal of Cryptographic Engineering, shaping it into a leading publication for research on cryptographic hardware and embedded systems.

Among his practical contributions, Koç was one of the designers of the RSAREF software toolkit, a widely used reference implementation of RSA cryptography. His research spans the design and optimization of secure hardware and software implementations of cryptographic systems, architectures for finite field and ring arithmetic underpinning modular multiplication and elliptic-curve cryptography, and countermeasures against timing, cache, and microarchitectural side-channel attacks. More recent work has addressed post-quantum cryptography, homomorphic encryption, random number generation, and privacy-preserving computation. He has also been involved in the steering committees for workshops including WAIFI and PROOFS.

Koç has directed research through the Koç Lab, engaging postgraduate researchers in cryptographic engineering, secure hardware architectures, and privacy-enhancing technologies for embedded and cloud environments. His output includes numerous patents, high-impact journal articles, and several books.

Selected Publications

Koç's book-length works include Cryptographic Algorithms on Reconfigurable Hardware (2007), Cryptographic Engineering (2009), Open Problems in Mathematics and Computational Science (2015), Cyber-Physical Systems Security (2018), and Partially Homomorphic Encryption. He has also edited multiple volumes of conference proceedings on cryptographic hardware and finite field arithmetic.

Recognition

Koç has received a number of awards and honors across his career. In 2001 he received the Award for Outstanding and Sustained Research Leadership from Oregon State University. In 2007 he was elected a Fellow of the Institute of Electrical and Electronics Engineers (IEEE) for contributions to cryptographic engineering, and in 2023 he was elevated to IEEE Life Fellow for sustained contributions to the field. In 2020 he received the International Fellowship for Outstanding Researchers from the Scientific and Technological Research Council of Türkiye (TÜBİTAK). His research has also been recognized with the ACM CCS Test of Time Award and the USENIX 2024 Distinguished Paper Award.
