A security-tagged architecture is one that applies tags on data to detect attack or information leakage, tracking data flow.The previous studies using security-tagged architecture mostly focused on how to utilize tags, not how the tags are implemented. A naive implementation of tags simply adds a tag field to every byte of the cache and the memory. Such technique, however, results in a huge hardware overhead.This paper proposes a low-overhead tagged architecture. We achieve our goal by… CONTINUE READING
