Mitigating Smart Card Fault Injection with Link-Time Code Rewriting: A Feasibility Study
[chapter]
2013
Lecture Notes in Computer Science
Preserved Fulltext
We present a feasibility study to protect smart card software against fault-injection attacks by means of binary code rewriting. ...
We implemented a range of protection techniques in a link-time rewriter and evaluate and discuss the obtained coverage, the associated overhead and engineering effort, as well as its practical usability ...
First, inserting redundancy involves static as well as dynamic code duplication: In Figure 2 , the load occurs twice in the code statically and it will be executed twice dynamically. ...

Our experiments with 11 previously known, real-world performance bugs show that TODDLER finds these bugs with a higher accuracy than the standard Java profiler. ...
TODDLER reports code loops whose computation has repetitive and partially similar memory-access patterns across loop iterations. Such repetitive work is likely unnecessary and can be done faster. ...

In this paper, we demonstrate that TaintTrace is effective in protecting against various attacks while maintaining a modest slowdown of 5.5 times, offering significant improvements over similar tools. ...
The challenge lies in minimizing the run-time overhead of the tool. TaintTrace uses a number of techniques such as direct memory mapping to optimize performance. ...
Twolf with test input is the exception because its native execution is already very fast, using only about 0.4s, in which case our tracing tool spent a large portion of time in initialization (about 80% ...
