The design of a quantum computer would have a tremendous impact on the cryptography used nowadays, particularly in the asymetric cryptography do-main. Moreover, the increasing use of connected objects in our everyday lifeand their limitations in term of computation capabilities and available memory make them a key target. This thesis was focused on those two problematics, and is divided into three independent axis. The first one proposes the conception of a cryptographic primitive called Hash Proof System (HPS). Based on the language of RQC ciphertexts, we will show how to construct such a primitive and will present two applications of it : a witness encryption scheme in one hand and a password authenticated key exchange protocol on the oth...
