摘要： A device and a method for executing a program, and a method for storing a program are described. The method of executing a program includes a sequence of instruction cycles, wherein each instruction cycle comprises: updating the program counter value; reading a data word from a memory location identified by the updated program counter value, wherein the data word comprises an instruction and a protection signature; determining a verification signature by applying a signature function associated with the program counter value to the instruction; executing the instruction if the verification signature and the protection signature are consistent with each other; and initiating an error action if they are inconsistent with each other. A method for storing a program on a data carrier is also described.

摘要： A method of operating a data processing system comprises: processing data words and switching between contexts; assigning a context signature Sig to any pair formed of a data word and a context; reading, within a current context, a data record from a memory unit, the data record comprising a payload data word and a protection signature; providing, as a verification signature, the context signature Sig of the payload data word and the current context; checking the verification signature against the protection signature; and generating an error signal if the verification signature differs from the protection signature.
