Jintide Utilizing Low-Cos t Reconfigurable External Monitors to Substantially Enh

Abstract

Nowadays, hardware security has become a serious concern for modern CPUs. State-of-the-art detection approaches rely heavily on trustworthy and intimate internal states, incurring significant design/operation overheads and additional risks to security and intellectual property. This article proposes an archi- tecture called Jintide, which utilizes trusted external monitors to validate an untrusted CPU chip at runtime. This architecture records, replays, and analyzes the CPU’s IO and memory behavi
