Abstract(in English) | Keystone Enclave, one of the TEE implementations in RISC-V, lacks flexibility in data transfer between the host and the isolated environment, making it difficult to transfer large amounts of data efficiently. In this paper, we propose a more secure and efficient data transfer method for Keystone Enclave. The evaluation shows that the proposed method improves the data transfer speed by 2.3x compared to existing implementations. As an example of the application of the proposed method, we implemented and evaluated the Secure Boot signature computation for boot images on Keystone. We confirmed that the impact of data transfer on the entire application was as small as 3-5%. |
