Abstract
A method for enabling enclave migration is provided, where the contents of the enclave and its sealed data are transferred from a sending host to a receiving host. An attestation is performed between a security monitor of the sending host and a security monitor of the receiving host, where the attestation includes an exchange of a shared cryptographic key K between the two security monitors. The shared cryptographic key K is used to implement a secure communication channel between the two security monitors. The two security monitors execute, via the secure communication channel, a predetermined transfer protocol. The predetermined transfer protocol includes an initial exchange of verification messages between the security monitors to verify that both security monitors are ready and can execute the transfer, and a subsequent transfer of enclave data between the security monitors.
