Abstract
Techniques for securely provisioning a set of enclaves are described. A contract owner may register with a shared registry. A subset of enclaves may be selected to be provisioned from among a plurality of enclaves. A keyshare may be requested from one or more provisioning services for each of the subset of enclaves to be provisioned. The requested keyshares may be received from each provisioning service for each of the subset of enclaves to be provisioned. For each of the selected enclaves, the received keyshares may be sent for verification by the enclave. Each of the selected enclaves may send an authenticated and encrypted key derived from the received keyshares.
