People of ACM Profile

Kim-Kwang Raymond Choo holds a Ph.D. in information technology from Queensland University of Technology, Australia. Prior to starting his Cloud Technology Endowed Professorship at UTSA, Professor Choo spent five years working for the University of South Australia, and five years working for the Australian Government Australian Institute of Criminology.

He was a visiting scholar at INTERPOL Global Complex for Innovation in 2015, a visiting Fulbright scholar at Rutgers University School of Criminal Justice and Palo Alto Research Center (formerly Xerox PARC) in 2009, and an Honorary Commander, 502nd Air Base Wing, Joint Base San Antonio-Fort Sam Houston, from 2017 to 2019. He was appointed as an external paid expert to provide expert advice to two companies on their U.S. Department of Energy SBIR/STTR Phase I proposals in 2020 and 2021, expert insights in writings to inform North Atlantic Treaty Organization (NATO) Allied Command Transformation (ACT) Innovation Hub’s Warfighting 2040 report in 2020. He has reviewed for L’Oréal-UNESCO For Women in Science 2021 International Awards (physical sciences, mathematics and computer science), Canada Research Chairs Program (Tier 1 Chair – 2019), Science Foundation Ireland Research Professorship Programme in 2019, Irish Research Council’s Advanced Laureate Awards in 2018, etc.

He is the founding co-Editor-in-Chief of ACM Distributed Ledger Technologies: Research & Practice, and founding Chair of IEEE Technology and Engineering Management Society (TEMS)’s Technical Committee on Blockchain and Distributed Ledger Technologies.

Raymond’s areas of research include big data analytics, cyber security and digital forensics. His research has been funded by U.S. funding agencies (NASA, National Security Agency, National Science Foundation, U.S. Department of Defense, CPS Energy, LGS Innovations, MITRE, Texas National Security Network Excellence Fund) and Australian funding agencies (Australian Government National Drug Law Enforcement Research Fund, Australian Government Cooperative Research Centre for Data to Decision, Lockheed Martin Australia, auDA Foundation, Government of South Australia, BAE Systems stratsec, Australasian Institute of Judicial Administration Incorporated, Australian Research Council), etc..

His research has been widely cited, including in government reports of the Australian Government, United Nations Office on Drugs and Crime (UNODC), U.S. CRS Report for Congress (Prepared for Members and Committees of Congress), International Centre for Missing & Exploited Children, International Telecommunication Union (ITU), and UK Home Office. One of his published cryptographic protocols was included in two independent submissions to the IEEE 802.11, the working group setting the standards for wireless LANs, by computer scientists from Fujitsu Labs in America; and the IETF / Network Working Group by a team of computer scientists from Tropos Networks (U.S.), Toshiba, Huawei, and University of Murcia. Another of his published protocol was used in the P2P solution of the Milagro TLS (pairing-based cryptography for Transport Layer Security) presented to the IETF by researchers from MIRACL Ltd in 2016. His published design principle about how session keys should be constructed in cryptographic (key establishment) protocols that result in significant benefits for their security was cited in a special publication (SP 800-56A) – Recommendation for Pair-Wise Key Establishment Schemes Using Discrete Logarithm Cryptography – by the U.S. National Institute of Standards and Technology, as well as the subsequent versions (Revision 2, 2013, and Revision 3, April 2018).

He is the co-inventor of two Australian PCT and one Australian provisional patent applications on digital forensics and mobile app security filed in 2015. He is the co-inventor of three regular U.S. patent applications on lightweight cryptographic scheme for mobile devices and a code-based cryptographic scheme (i.e. post-quantum).

He is an ACM Distinguished Speaker and IEEE Computer Society Distinguished Visitor (2021 – 2023). In 2015 he and his team won the Digital Forensics Research Challenge organized by Germany’s University of Erlangen-Nuremberg. He is the recipient of the 2019 IEEE Technical Committee on Scalable Computing Award for Excellence in Scalable Computing (Middle Career Researcher), the 2018 UTSA College of Business Col. Jean Piccione and Lt. Col. Philip Piccione Endowed Research Award for Tenured Faculty, the Outstanding Associate Editor of 2018 for IEEE Access, the British Computer Society’s 2019 Wilkes Award Runner-up, the 2014 Highly Commended Award by the Australia New Zealand Policing Advisory Agency, the Fulbright Scholarship in 2009, the 2008 Australia Day Achievement Medallion, and the British Computer Society’s Wilkes Award in 2008. He has also received best paper awards from IEEE Systems Journal in 2021, 2021 IEEE Conference on Dependable and Secure Computing (DSC 2021), IEEE Consumer Electronics Magazine for 2020, Journal of Network and Computer Applications for 2020, EURASIP Journal on Wireless Communications and Networking in 2019, IEEE TrustCom 2018, and ESORICS 2015; the Korea Information Processing Society’s Journal of Information Processing Systems (JIPS) Outstanding Research Award (Most-cited Paper) for 2020 and Survey Paper Award (Gold) in 2019; the IEEE Blockchain 2019 Outstanding Paper Award; and Best Student Paper Awards from Inscrypt 2019 and ACISP 2005.
