—RISC-V指令集的一个重要卖点是ISA和ISA的实现之间的分离，从而带来设计的灵活性。我们认为，对于安全实施来说，这种灵活性通常是一个漏洞。对于硬件攻击者来说，指令执行的副作用是不容忽视的。因此，ISA 接口和实现之间的严格分离是不可取的。我们建议安全 ISA 可能需要额外的实施限制。作为示例，我们描述了用于开发抗电源侧信道软件的指令集
—An important selling point for the RISC-V instruction set is the separation between ISA and the implementation of the ISA, leading to flexibility in the design. We argue that for secure implementations, this flexibility is often a vulnerability. With a hardware attacker, the side-effects of instruction execution cannot be ignored. As a result, a strict separation between the ISA interface and implementation is undesirable. We suggest that secure ISA may require additional implementation constraints. As an example, we describe an instruction-set for the development of power side-channel resistant software
