BoolTI is the newest project at the Selmer center, with Lilya Budaghyan as the PI and a budget of 10.5 MNOK for the period 2021-2024. Other key members are Claude Carlet, George Petrides, and Vincent Rijmen.
Cryptographic ciphers serve the very important function of securing our every day communication and data against unauthorised access. They are in use everywhere: web-browsers, mobile phones, payment cards, tv-decoders, smart cards, etc. The fact that more and more of them are now run in embedded devices makes the rather recent side channel attacks (SCA) a huge threat: unwanted information leakage during the execution of the algorithms could potentially compromise their security. The project will study Boolean functions used as building blocks in cryptographic ciphers in order to find ways to prevent SCA.
