Abstract
A fork support is provided for duplicating an application running inside an enclave entity. In this regard, a request to duplicate an application running inside a first enclave may be received by one or more processors of a host computing device of the first enclave. A snapshot of the first enclave including the application may be generated. The snapshot may be encrypted with a snapshot key and copied to untrusted memory of the host. A second enclave may be generated. The snapshot key may be sent from the first enclave to the second enclave through a secure communication channel. The encrypted snapshot may be copied from the untrusted memory of the host into the second enclave. The encrypted snapshot may be decrypted inside the second enclave with the snapshot key.
