He is responsible for the cryptanalysis of many real-life ciphers used by hundreds of hundreds of millions of people every day, such as the Bluetooth cipher E0, the automobile cipher KeeLoq and the MiFare Classic Crypto-1 system which is very widely used in public transportation (e.g. Oyster Card) and building access control cards.

A team directed by Dr. Courtois has won the UK University Cipher Champion 2013 award (older link) on 12 March 2013.

Post-quantum Cryptography:

He has authored or co-authored 20 papers in Post-Quantum Cryptography. 19 are listed here: http://pqcrypto.org/mq.html (key words: HFE, Sflash, Quartz), and one more is listed here http://pqcrypto.org/code.html.
