Distributed Authentication Framework Leveraging Multi-Party Computation In A Scalable Tree-Based Architecture (Univ. of Central Florida, Louisiana State)

Researchers from the University of Central Florida and Louisiana State University have introduced a new distributed authentication framework called AuthenTree, leveraging multi-party computation (MPC) in a scalable tree-based architecture. This framework aims to enhance security in chiplet-based heterogeneous systems by enabling secure chiplet validation without exposing raw signatures, distributing trust across multiple integrator chiplets. AuthenTree has shown minimal overhead, with an area as low as 0.48%, an overhead power under 0.5%, and an authentication latency below 1 microsecond, surpassing previous solutions. The framework is designed to address security threats in post-fabrication environments and establish a more efficient and scalable security solution for next-generation chiplet-based systems.
