Researchers introduce CVA6-CFI, an implementation of Control-Flow Integrity extensions for the RISC-V architecture, providing hardware-level security against code reuse attacks. The paper presents initial performance and security evaluations of the design, which enhances protection in embedded and high-performance systems. This work contributes to the growing ecosystem of security features for open-source RISC-V processors.
Background
Control-Flow Integrity (CFI) is a critical security mechanism that prevents malicious manipulation of program execution flow, commonly targeted in code injection and return-oriented programming attacks. RISC-V is an open-source instruction set architecture gaining significant traction in academic and industrial applications.
