In this paper, we propose the design of a generic security interface for RISC-V. This interface increases flexibility of security modules by creating an environment that can operate independently on a host processor. We also present an application using this interface for the memory protection. To check the feasibility of our idea, we implement an early prototype where a RISC-V processor is connected with the proposed hardware components using our interface. The empirical results show that our security interface has enabled a security module operated independently of the processor with no performance and low area overhead.
