Abstract: A method and apparatus for providing automatic international and local call dialing in a mobile communication terminal. The apparatus includes a country identification unit for receiving country identification information from a network in which the mobile communication terminal is currently located; a memory for storing country identification information, a country codes, and international access codes corresponding to the country codes; and a controller for extracting from the memory a country code corresponding to the country identification information received from the country identification unit, comparing the extracted country code with a country code included in a phone number for an outgoing call, and making a local call or an international call according to whether the country codes are identical.

Abstract: A security device includes a secure processor, a mail box, a cryptographic intellectual property (IP), a secure direct memory access (DMA) circuit, and an internal memory. The secure processor provides an isolated execution environment. The mail box transfers a request from a CPU to the secure processor. The cryptographic IP performs one or more secure operations, including a signature certification operation, an encryption/decryption operation, and an integrity verification operation, on secure data within the isolated execution environment and without intervention of the CPU. The secure DMA circuit controls the one or more secure operations within the isolated execution environment, wherein only the secure processor is configured to control the secure DMA circuit. The internal memory stores the secure data on which the one or more secure operations are performed. The cryptographic IP includes a DMA circuit configured to control data access to an external storage.

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.
