Abstract
A system for performing a multi-party computation (MPC) operation may include an MPC node executed in a secure enclave. The MPC node includes executable instructions injected into the secure enclave to create an execution environment. The secure enclave performs an attestation check on the execution environment, generates a result of the attestation check, and cause the secure enclave to create a cryptographic signature on the result of the attestation check. The system may also include an attestation node in communication with the secure enclave. The attestation node verifies the cryptographic signature on the result of the attestation check and cause a decryption of an encrypted private cryptographic key shard to generate a decrypted private cryptographic key shard. The decrypted cryptographic key shard is used by the MPC node to perform part of the MPC operation.
