Presentation and scientific foundations

The research work within the project-team is mostly devoted to the design and analysis of cryptographic algorithms, in the classical or in the quantum setting. This work is essential since the current situation of cryptography is rather fragile. Many cryptographic protocols are now known whose security can be formally proved assuming that the involved cryptographic primitives are ideal (random oracle model, ideal cipher model...). However, the security of the available primitives has been either threatened by recent progress in cryptanalysis or by the possible invention of a large quantum computer. In other words, there is usually no concrete algorithm available to instantiate in practice the ideal “black boxes” used in these protocols!

In this context, our research work focuses on both families of cryptographic primitives, symmetric and asymmetric primitives.
