Post-Quantum Cryptography Impact on I2C Communication and Security Protocols

Learn about the challenges posed by post-quantum cryptography (PQC) algorithms on I2C interfaces in server management during this 18-minute conference talk from HPE's Paul Kaler. Explore how quantum computing threatens current encryption methods and examine the development of PQC algorithms and CNSA 2.0 standards. Discover why I2C, the primary sideband interface used by Baseboard Management Controllers for device management, faces significant limitations when implementing larger PQC signatures required for secure firmware authentication and attestation through SPDM protocols. Gain insights into potential industry solutions for addressing these implementation challenges in server hardware security.
