KeyTalk is the first company to realise safe private key storage with “Key Attestation”

15 Sep ‘22

The benefit of customer driven development is being able to respond more quickly to new questions from from the industry regarding automated PKI management.

Rohde & Schwarz, a world-leading producer of, among other things, test and measurement equipment, came to us 10 months ago via our partner DigiCert QuoVadis with the challenging request of whether we could provide TPM Key Attestation for the private key for authentication certificates used on the Linux based workstations by their engineers. R&S had been looking for a solution for some time, but to no avail.

We have been working for the past few months in close cooperation with R&S to meet their specific demand, and the operational tests of this highly innovative functionality have recently been successfully concluded. At this moment we are still working hard, mainly to support the IT management organisation with the convenient acquisition of the “Endorsement Certificate” from various manufacturers of TPM (Trusted Platform Module) chips, which serve as a kind of mini HSM on a laptop or workstation.

With this new functionality from the KeyTalk Certificate & Key Management System (CKMS), R&S is able to guarantee the safe use of authentication certificates for the many Linux based workstations of the engineers. These certificates are, among others, used for the very secure communication via MS Teams, where there is mathematical evidence (Attestation) that the private key of the certificate is only located on the TPM chip of the laptop/workstation.

If you would like to know more about this new functionality, please do not hesitate to contact us.

Enjoy the beautiful late summer!
