Abstract | Disclosed herein are systems, methods, and computer-readable media for enabling more secure multi-party computations (MPCs) using a trusted execution environment (TEE). In one aspect, a method includes executing, by a first MPC computer, a secure MPC protocol in a first TEE of the first MPC computer. The first MPC computer generates a request to a second MPC computer executing the secure MPC protocol in a second TEE of the second MPC computer. The first TEE determines that one or more attestation conditions are met by the first MPC computer executing the secure MPC protocol in the first TEE. In response to determining that the one or more attestation conditions are met, the first TEE generates an attestation token including one or more digital signatures for the secure MPC protocol executing in the first TEE. The first MPC computer sends the attestation token with the request to the second MPC computer. |
