Quantum readiness: Introduction to Modern Cryptography

This article is the first of a series of articles regarding Post-Quantum Cryptography in 2024. It builds upon Synacktiv's 2021 article, "Is it post quantum time yet?", by presenting the evolutions that happened since then in the PQC world as well as various constructions that will be reused in the next articles. These articles will especially focus on giving the reader a good understanding of the attack surface one should consider when designing and implementing a PQC algorithm. This article considers that the concepts presented in o...

Is it post quantum time yet?

Quantum computing. Among all the fashionable IT buzzwords, this one comes prominently. Quantum computing, or the idea people get of it, feeds a lot of fantasy. This trend is supported by the news that sometimes relay hazy information about a topic they do not fully grasp. Getting a precise view of the state of quantum computing and its implications on security is not easy if you are not familiar with the topic. In this article, we will try to answer this seemingly simple question: is it post quantum time yet?
