SpletWhen the private key is managed by the TPM as a non migratable key only the TPM that created the key may use it. Hence, a message encrypted with the public key, “bound” to a particular instance of a TPM. It is possible to create migratable private keys that are transferable between multiple TPM devices. Splet30. nov. 2013 · The stpm-keygen binary asks the TPM to generate a key, and the TPM hands back the public portion of the key, and a “blob” that has no meaning to anyone except the TPM.

Splet07. jun. 2024 · The following simple patch fixes the logic, and has been tested for all four combinations of migratable and non-migratable trusted keys and parent storage keys. With this logic, you will get a proper failure if you try to create a non-migratable trusted key under a migratable parent storage key, and all other combinations work correctly. SpletCertification of a key, which a Trusted Platform Module (TPM) has attested as being non-migratable, can be performed in a single round trip between the certificate authority (CA) and the client that requests the certificate.
