About UCL Code Breaking Competition
The Cryptanalysis (COMPGA18/COMPM068) module in UCL’s MSc Information Security provides students with the foundational knowledge to analyse cryptographic systems. In 2016, it was taught by Nicolas T. Courtois, Jonathan Bootle, Christophe Petit and Mary Maller. Some course slides, tutorials and labs we use in GA18 can be found here.
To give students a more realistic (and enjoyable) experience there is no written exam for this module; instead the students are evaluated based on [individual] programming projects and a [group] code breaking competition. UCL has a strong tradition of experimental research and we have been running many student competitions and hacking events in the past. In March 2013 a team directed by Dr Courtois won the UK University Cipher Challenge 2013 award, held as part of the UK Cyber Security Challenge.
This year the competition has been about recovering private keys in real-life systems. It has involved the study of random number generators, software reverse-engineering, password cracking, elliptic curve cryptography, hash functions, exploration of large datasets, programming and experimentation, optimization, visualization and statistics, and complex key recovery attacks based on algebraic exploitation of various types of special events. We also have developed passive and active side channel attacks with cache type of leakage, aiming at recovering private keys and with a variety of implementations. In the past years, we have allowed participants from other London universities. For further information, contact Dr Nicolas Courtois.
About the Prize Winners:
- Iason Papapanagiotakis-Bousy (left) is a UCL M.Sc. InfoSec student from Greece.
During the competition he has broken hundreds of thousands of real-life passwords including some 200 passwords which have never been discovered before. He has done remarkable work on algebraic cryptanalysis on Simon block cipher, which work has been submitted for publication and will be published in proceedings of SECRYPT 2016 conference this summer. He was also a member of UCL team in the international CTF (Capture The Flag) hacking competition. He has excellent skills in scientific data analysis and modeling and has greatly contributed to our blockchain high-speed data mining effort.
- Chris Jeonghyuk Park is a UCL M.Sc. InfoSec student from South Korea. He was also a member of the same UCL team in CTF, and also a prolific password cracker able to recover countless passwords which no one has found before. He is an experienced Linux/C software developer. Furthermore, he also has distinguished himself in blockchain data mining. His expertise is problem solving, algorithms, network & system security. He recently has studied and did a presentation about Ethereum mining internals. This month he is starting an internship at a FinTech/blockchain company in central London.
- Patrick Hough is a UCL Maths student (cf. here). His primary interest is analytic number theory, and he has been in the recent months working with Prof. Andrew Granville on (recently) very famous questions of biases in prime numbers. He has been one of the very best first year students at UCL faculty of mathematical and physical sciences in 2013.
- Lim Min (right) is a visiting UCL Maths student from Singapore. She is a born problem-solver and enjoys applying mathematics to real-life questions. During our lectures and tutorials, she distinguished herself by her questions and her natural grasp for understanding how various events affect the feasibility and success rate of cryptanalytic attacks.
