A secret sharing scheme that can be executed on a single server using TTP has been proposed. In this method, the entire computation process on the server can be made public if random numbers corresponding to the key can be managed securely, and since it can be executed on a single server, no communication occurs and very fast secret computation can be realized. However, this method is designed for semi-honest adversaries and not for malicious adversaries. In addition, although TTPs are generally assumed to be trustworthy, if there is a malicious adversary in the TTP and he can learn the computation process in the server, the secret information and the computation results will be leaked. In this paper, we propose a secure computation using secret sharing scheme, that can be configured on a single server and is safe from malicious adversaries and cheaters in the TTP. In order to achieve this, we combine TTP and TEE, but we assume that the server discloses the entire computation process, which means that the server and the programs installed in the TEE are public and can be verified by anyone. Thus, if the server and its TEEs are legitimate, this can protect confidential information from unauthorized persons in the TTP. As a result, a single server can realize secure secret computation against malicious adversaries and cheaters in the TTP, and also maintain high-speed processing. |
