Abstract: Provided are an electronic system, an integrity verification device, and a method of performing an integrity verification operation. The electronic system includes: a memory device; a processor configured to provide a plurality of configuration records corresponding to a plurality of verification data stored in the memory device, each of the configuration records including a start address, a data length, and a reference hash value for a corresponding verification data; and an integrity verification device configured to: store the configuration records, select a configuration record, directly access the memory device to read verification data, corresponding to the selected configuration record, based on the start address and the data length included in the selected configuration record, perform a hash operation on the verification data to obtain a verification hash value, and output an interrupt signal based on the verification hash value and the reference hash value comprised in the selected configuration record.
