### AI overview

Microsoft is testing post-quantum cryptography interoperability with certificate authorities, including DigiCert, through a controlled pilot. The article describes the need to validate compatibility across platforms, protocols, devices, suppliers and existing infrastructure before deployment.

### Source excerpt

Post-quantum interoperability depends on more than whether individual algorithms work. As quantum readiness moves from planning to implementation, testing becomes the bridge between technical standards and deployable protections. Microsoft Corp. is bringing certificate authorities into that process. Readiness must begin with operational needs, according to Karina Sirota Goodley (pictured, right), senior security product manager at [...] The post Microsoft puts post-quantum interoperability to a real-world test appeared first on SiliconANGLE.
