发明名称 Method of dynamic protection of data during the execution of a software code in intermediate language in a digital apparatus
摘要 The invention concerns a method for protecting the data of an application compiled in intermediate for execution executed on a digital apparatus equipped with a virtual machine managing the execution of the code via a execution stack defining at least one stack frame corresponding to a method called during the execution of the code. A secured execution mode of the code involves the determination of at least one global checksum associated with each stack frame and, each time that a datum of the code is manipulated, the calculation of a local checksum associated with that datum. The calculation is on one hand, on the global checksum associated with the stack frame corresponding to the manipulated datum and, on the other hand, on at least one part of the other data constituting the stack frame.
