Patent ID: 8095801

Claim:
A method of protecting a microcomputer system against manipulation of data block stored in a memory assembly of the microcomputer system, the method comprising the steps of: partially marking the data block, wherein a signature of at least part of the data block is formed using an asymmetrical encryption method in conjunction with one of a new programming and a reprogramming of the microcomputer system; transmitting the data to the memory assembly; checking at least a part of the marked data, wherein the checking of the marked data is performed in the microcomputer system within a framework of processing of the data block in the microcomputer system such that a portion of the data block stored in the memory assembly is checked when the processing of the data block leaves sufficient computing capacity for the checking, whereby the entire data block is checked after a specified period of time; and adjusting the operation of the microcomputer system if manipulation of the data block is detected.
