Abstract: According to an embodiment, an encryption key generating apparatus includes a converting unit to convert input data using a physically unclonable function and outputs output data; a memory to store a plurality of pattern data, each of which is a partial data in the output data indicated by one of a plurality of index data; a generating unit to generates an encryption key on the basis of the plural of index data; and a comparing unit to compare the output data with the plural of pattern data to detect plural of locations in the output data at which partial data similar to the plural of pattern data is present. The generating unit reproduces, as the plural of index data, the plural of locations detected by the comparing unit and reproduces the encryption key on the basis of the plural of index data that have been reproduced.

Abstract: A broadcast station synchronization method in a mobile terminal operating with a system clock different from the reference clock of a broadcast station, wherein a clock synchronized with the broadcast station is reproduced according to an internal reference clock corrected by the reference time information from the broadcast station, a difference between an elapsed time at a predetermined time interval and the audio reproduction time is detected, the audio reproduction time is adjusted to cancel the difference, and the PCM transmission for reproducing the audio uses a signal indicating the PCM data transmission completion as a trigger for latching the internal reference clock count unit reproducing the clock synchronized with the broadcast station so as to acquire the clock time synchronized with the broadcast station of the same period as the audio reproduction time per a predetermined period, thereby performing synchronization with the broadcast station.

Abstract: A secure embedded system that uses cryptographic and biometric signal processing acceleration is described. In one embodiment, the secure embedded system is configured as a wireless pay-point protocol for brick-and-mortar and e-commerce applications in which biometric information is localized and does not require transmission of biometric data for authentication. In one embodiment, a key-generation function uses a dynamic key generator and static biometric components. In one embodiment, an embedded system design methodology provides hardware and software acceleration transparency.
