Abstract
The present document compares a selection of proposals for quantum-safe key exchanges taken from the academic literature. In particular, it includes key exchanges based on the Learning with Errors (LWE), Ring-LWE and Supersingular Isogeny Diffie-Hellman (SIDH) problems, as well as key exchanges constructed from the Niederreiter and NTRU key transport schemes.
The present document gives an overview of each key exchange, lists proposed parameters and gives software performance estimates on a range of processors. It also discusses various security and implementation considerations such as active attacks and side-channel vulnerabilities.
