【 摘 要 】

Cracking smartcards has always been a prized hobby, for theacademic glory, for fun (ha, breaking the selfclaimed unbreakable...) and for profit (ask the organized crime). Stateoftheart techniques include laser blasts that inject various transient or permanent faults in a program execution, potentially making the smartcard do whatever the attacker wants. After a brief recap of the attack tools and their effects, this article describes how the programmer can protect his/her code using software techniques ranging from cookbook recipes to tool chain automation and how (s)he can evaluate the robustness of his/her code by means of fault
