With fault attacks on smart cards being a method of performing unauthorized transactions with credit cards, various research papers have proposed software implemented countermeasures against these attacks. The aim of this report is to investigate the details required to implement a tool for automatically inserting countermeasures into smart card applets, specifically Java Card applets. The tool developed implements branch duplication and call graph integrity based on various analyses and a call graph provided with the used bytecode optimization framework called Soot. The aim of the tool is to easen the development process of a Java Card applet developer that needs to secure the applet. The report outlines the considerations that was made during the development of the tool as well as identifies situations where the tool has its shortcomings along with a proposal to a solution of the shortcomming.
