Method for executing a program intended to be interpreted by a virtual machine protected against fault injection attacks

摘要

The present invention particularly concerns a method for executing a program (P) intended to be interpreted by a virtual machine (M), the method comprising steps of determination (102) of a reference code instruction to be interpreted when executing the program, interpretation (112) by the virtual machine of the reference code instruction using machine code. This method also comprises read-out (106) of interpretation rights data (DR) indicating a portion (P1) of the program containing code instructions interpretable by the virtual machine and, on the basis of read-out data, checking the presence (110) of the reference code instruction in the portion (P1) of the program (P), the interpretation of the reference code instruction being implemented by the virtual machine (M) only if the reference code instruction is contained in the portion (P1) of the program (P).
