Countermeasures Mitigation for Designing Rich Shell Code in Java Card
Résumé
Recently, logical attacks have been published that target Java based smart card. They use dynamically a type confusion which is possible if type verification is not performed. Countermeasures have been introduced on recent smart card to avoid executing rich shell code and in particular dynamic bound checking of the code segment. We propose here a new attack path for performing a type confusion that leads to a Java based self modifying code. Then, we propose to improve the previous counter measure to mitigate this new attack.
