JCVM bytecode execution protection against fault attacks

摘要

The invention relates to a computing device comprising means to store and execute bytecodes, the computing device storing bytecodes which comprise a bytecode for calling a method. An attack detection bytecode is present after the bytecode for calling the method, and when executing bytecode, the computing device is set, upon return from the method, to continue bytecode execution after the attack detection bytecode. The invention also relates to a procedure for generating secure bytecode and to an applet development tool.
