Challenges in Standardization of Post-Quantum Cryptography (Q30c)
In 2017, NIST started a process to standardize a new generation of public cryptography that remains safe against a quantum computer. This process has been now finalized and new post-quantum cryptosystems are defined. That’s not the end of the standardization of post-quantum cryptography. On the contrary, many SDO (Standards Developing Organizations) will start or accelerate the integration of post-quantum cryptography into security protocols. Challenges are numerous such as maintaining interoperability and ensuring a reasonable efficiency. The goal of this talk is to overview the most recent activities of SDO in post-quantum cryptography with a focus on ETSI, ITU, IETF, and new groups at IEEE. We will then overview the recent works at IETF LAMPS on post-quantum versions of CMS and PKIX.
