Securing RISC-V Third-Party IP: Enabling Comprehensive CWE-Based Assurance Across the Design Supply Chain

RISC-V adoption continues to accelerate across commercial and government microelectronics programs. Whether open-source or commercially licensed, most RISC-V processor cores are integrated as third-party IP (3PIP), potentially introducing supply chain security challenges that demand structured, design-level assurance.

As systems become more heterogeneous and interconnected, design supply chain security is no longer a documentation exercise, but an engineering challenge. A single weakness in processor IP can cascade into systemic risk. That reality makes scalable, repeatable 3PIP assurance essential, especially for RISC-V cores deployed in mission-critical environments.

From Third-Party IP Risk to Repeatable Assurance

Traditional IP integration workflows often rely on vendor claims, checklist-based reviews, and limited test evidence. While helpful, these approaches rarely provide design-level assurance across all relevant weakness classes. To address this gap, a Common Weakness Enumeration (CWE)-based methodology enables structured, measurable, and portable security validation.

A structured CWE-based methodology replaces ad hoc reviews with measurable validation. Relevant weaknesses are scoped from the MITRE database, translated into security requirements, verified through executable properties and tests, and captured as traceable assurance artifacts.

The outcome is not simply test coverage, but documented security assurance tied directly to recognized weakness definitions.
