Post-Quantum Cryptography: A Primer for C-Suite (Q01a)
Several PQC key-exchange and signature algorithms are undergoing standardization by agencies such as NIST and IETF, with others in draft or evaluation phases. International standards bodies like ENSIA and CACR are also involved. This talk briefly explains the mathematics of various PQC algorithms and their strengths and limitations. It also discusses contenders for future standardization and explores the suitability of different PQC algorithms for various deployment scenarios within enterprise IT infrastructures. The presentation outlines an approach for enterprises to answer key questions regarding the need for PQC, deployment timelines, and security measures, focusing on Hybrid PQC—an approach combining PQC and traditional public-key cryptography to ensure security even if one method is compromised.
