A data conjunction unit(240) conjuncts texts to be encrypted to an XOR-calculated data, and a data padding unit(250) performs the padding process of the conjunct data. An SHA-1 Hash calculation unit(270) supports the SHA-1 Hash calculation of the padded data. The data selection unit selects the results of the SHA-1 Hash calculation or the texts to be encrypted and transfers the results or the texts to the data conjunction unit. A controller(260) reads out the data necessary for performing the encrypted operation and controls the operation of the data conjunction unit and the data padding unit.

Abstract: A method and a system for enhancing security of a mobile terminal are provided to improve data security by storing key data of a communication terminal and a master key of a security chip both in a mobile communication server and a security chip server. A mobile communication terminal includes a security chip(120) and a main system(110). The security chip stores an encryption key and registration data, which are provided from a registration/issuance server during an initialization process. The main system transmits and receives data with the security chip, receives the registration data which is encrypted by the encryption data, from the security chip, and stores the registration data. When the mobile communication terminal is used, the registration data in the security chip and the registration data in the main system are compared with each other, so that the user is authenticated, when the registration data are matched.

Abstract: A frequency sensing apparatus is provided to maintain safety of a hardware device by removing dangerous elements from the hardware device through sensing of changes in the frequency of a clock signal. A frequency sensing apparatus includes an integrator(11) and a comparator(12). The integrator receives clock signals and integrates the received clock signals. The comparator compares an output of the integrator with a predetermined threshold voltage. An output of the comparator indicates whether the clock signal is within a normal frequency range or not. The predetermined threshold voltage is set as a predetermined voltage equal to and more than an output voltage of the integrator corresponding to a lower limit frequency of the normal frequency range of the clock signal.
