Abstract
Described are a system, method, and computer program product for secure real-time n-party computation. The method includes communicating, to a trusted execution environment (TEE), a first computation input and a first portion of a one-time key. The method also includes receiving, from the TEE, an encrypted output of a computation based on the first computation input and a second computation input communicated to the TEE by a second computing device. The method further includes communicating the encrypted output to the second computing device and receiving a digital signature indicating that the second computing device received the encrypted output. The method further includes communicating the first portion of the one-time key to the second computing device and, in response to not receiving the second portion of the one-time key from the second computing device, executing a fallback computation process using the TEE and a shared ledger to determine the computation.
