The complexity of modern integrated circuits has made them vulnerable to malicious insertions and modifications known as hardware trojans. A comprehensive trojan taxonomy was recently developed and incorporated into a technique for quantitatively classifying trojans. This can provide valuable insights into the origins and risk of a trojan based on the corresponding attributes, but the method can be difficult to use and prone to error. Thus, a tool has been developed to automate this classification. Widespread use of this tool will lead to a comprehensive database with detailed descriptions of all known trojans which can be used as a centralized reference for attackers and defenders. A discussion of the automated tool design is given including a case study to demonstrate its usefulness.
