For the 2019 edition of the Science Festival, we received third grade classes. With my fellow research engineer Nathalie Bochard, we presented cryptography. We started with Caesar cipher, before discussing the team’s research topic of random number generation. We presented a random number generator based on ring oscillators, which we attacked by harmonic injection on the power supply to synchronize the oscillators and thus bias the generated random numbers.
For the first edition of European Researchers’ Night in Saint-Étienne, I led two small workshops :
Later on, along with five other researchers, we performed a theater play in which we talked about our research topics. For this, we had been coached by Sabrina from Ateliers de la rue Raisin, who designed and directed the play.
Along with the improvisation troup Ni pied ni clé, we performed the “Impro’Sciences” show. The audience could write down questions of their choice. Then, the troup presented two answers, a correct one and a completely wrong one. The audience then had to vote for the most convincing explanation. After that, some scientific background about the question was briefly discussed.
For Pint of Science 2019, my colleague Damien Robissout and I presented the usage of artificial intelligence for cybersecurity. After briefly talking about cryptography and neural networks, we did a hands-on demo. Someone from the audience had to type a message, along with a 4-digit PIN which was used to encrypt the message. A neural network that we had trained was fed with the power consumption of the microcontroler that performed the encryption in order to recover the 4-digit secret PIN. We then used it to decrypt the secret message.
In order to discover the Centre of Microelectronics in Provence, the four research departments designed an escape game, called Escape Clean Room. Participants had to solve six puzzles to escape the (simulated) clean room. The puzzles, designed by the research departments, were the following:
The Alkindi contest is an introduction to cryptography for 7th, 8th and 9th graders, organised by Animath and France-ioi. Regional winners could visit a research facility. We had PACA regional winners to visit the Centre of Microelectronics in Provence. I presented them frequency cryptanalysis applied to Caesar cipher, both in theory and practice!
Along with the improvisation troup Ni pied ni clé, we performed the “Impro’Sciences” show. The audience could write down questions of their choice. Then, the troup presented two answers, a correct one and a completely wrong one. The audience then had to vote for the most convincing explanation. After that, some scientific background about the question was briefly discussed.
For Ramène ta science 2017, I started by running a workshop for middle school students. In the “Draw my science” framework, I presented the Caesar cipher and how it could be cryptanalysed with a frequency analysis. Two teams later practiced the attack, attacking one another’s encrypted messages.
I then played in a theatre play, along with other researchers where we carried a criminal investigation using our scientific skills. To this end, I presented key exchange protocols.
For Fête de la Science 2016 at Jean Monnet University, I took part in a theatre play along with other researchers. We were coached by professional actors and played a fake “Three Minute Thesis” contest, which did not go as planned!
The Science & You event was organised in June 2015 by Lorraine University. I had the chance to present my PhD subject in drawings, cartoons more specifically. We were inspired by the Pr. Schmitt teleporter comic and were coached by the authors Peb & Fox. We had a quick training before applying these new techniques to our work. We then presented the result to the general public in Nancy.
