Zero Trust Cryptography and Quantum Safety Questions

Focuses on the role of cryptography within zero trust architectures and designing for resilience against current and future threats including quantum computers. Candidates should explain how cryptographic controls support zero trust goals: continuous verification, strong authentication, integrity and confidentiality at every communication and storage boundary, and minimized trust assumptions. Topics include key management and rotation, hardware security modules, mutual TLS and certificate management, authentication protocols, cryptographic agility, hybrid post quantum and classical schemes, post quantum algorithm choices and migration strategies, forward and backward secrecy, performance and operational trade offs, and how to integrate quantum safe approaches into cloud and hybrid deployments. Also covers how cryptographic design affects identity flows, service to service authentication, secure boot and attestation, and how to audit and validate cryptographic posture within a zero trust environment.
