DISTRIBUTED TRUSTED PLATFORM MODULE KEY MANAGEMENT PROTECTION FOR ROAMING DATA
Abstract: distributed security key management for protecting roaming data via a trusted platform module is performed by systems that include first and second processors, and first and second respective hardware security modules. the first security module encrypts a security key using a public key from the second security module, and the encrypted security key is provided to the second security module. a virtual machine (vm) executed by the first processor has a first virtual security module instance having state data that includes a storage key encrypting vm virtual disk data and that is encrypted with the security key. when a transfer condition is determined, the vm is transferred and executed by the second processor, using a second virtual security module instance, based on decrypting the security key by the second security module using a private key and decrypting the state data for the second virtual security module using the security key.
