Abstract
Disclosed is a system and method for enterprise authentication. An enterprise cluster includes one or more enterprise appliances employing virtual machines managed by at least one hypervisor. Each virtual machine is associated with a respective virtual Trusted Platform Module (vTPM) secured by the hypervisor. An enterprise key (EK) is provided to the appliances of the enterprise cluster and imported into a vTPM associated with each appliance. When a user authentication request is received by a first appliance, the first appliance obtains a user encrypted key which was previously encrypted by a different vTPM on a different appliance with the same EK. The vTPM then signs a challenge based on decrypting the user encrypted key with the EK, completing the user authentication request.
