METHOD FOR PROTECTING ELECTRONIC CIRCUITS, AND DEVICE AND SYSTEM IMPLEMENTING THE METHOD

摘要

The invention relates to a method for protecting at least one electronic circuit processing digital data. A configuration (303, 304) for protecting against errors introduced into said data is deduced (300) from a cartography (302) representing the faults of said circuit, said protection configuration corresponding to the configuration of at least one encoder and one decoder, the encoder generating code words consisting of data bits to which redundancy bits are added, said redundancy bits being generated such that the errors resulting from the faults indicated by said cartography (302) are corrected when decoding said code words. The invention also relates to a device for configuring and protecting memory areas and to a digital interconnection system implementing the method.
