Quantum is unimportant to post-quantum
By Opal Wright You might be hearing a lot about post-quantum (PQ) cryptography lately, and it’s easy to wonder why it’s such a big deal when nobody has actually seen a quantum computer.…
Most finite field Diffie-Hellman key exchanges used for web traffic are done using a small number of standardized parameter sets that are designed to mitigate weak subgroup attacks. Still, despite the consequences of errors and the availability of high-quality open-source libraries, Trail of Bits regularly finds dangerously flawed implementations of these algorithms in our code reviews. Submissions include signature algorithms based on problems related to elliptic curve isogenies, error correcting codes, and multivariate quadratics.
