| Guidelines |
| In post-quantum conditions, where a sufficiently large quantum computer is available to the adversary, the security of traditional cryptography protocols including all variants of RSA and the ubiquitous Diffie-Hellman key exchange can be broken in polynomial time using Shor's algorithm.
Supersingular Isogeny-based Diffie-Hellman key exchange (SIDH), as introduced by De Feo and Jao in 2011, is one of the best candidates for a key-exchange protocol in post-quantum settings. This thesis aims to design a communication protocol and to implement a software library that would allow to establish secure communication channels on the Internet, using the quantum-resistant SIDH as a main cryptographic primitive to provide confidentality and peer authentication. |
