Manipulation protected data processing system and associated method for protection against manipulation

摘要

A tamper-resistant method for preventing tampering using a glitch attack and a data processing system using the same are provided. The method includes reading out a first data from a region of the memory assigned by an address; reading out a second data from the region of the memory assigned by the address; determining whether the first data is identical to the second data; and fetching by the processor either one of the first and second data when the first data is identical to the second data.
