Key attestation, in this context, is the technical ability to prove to a remote party that a private key was generated inside, and is managed inside, and not exportable from, a hardware cryptographic module.
While several vendors offer remote key generation services, they all do it differently. This makes it hard or even impossible to scale usage of remote key attestation and create trust across the ecosystem.
The PKI Consortium has created a simple market survey, to make a list of the different available key attestation solutions being used by different vendors (including questions on how they work and are used technically). Once we have useful data, we can consider developing common standards that the industry may want to adopt.Click here to complete the remote key attestation survey
