摘要： According to an embodiment, a smart card includes a communication section, a generation part, a first record section and an erasure section. The communication section transmits and receives data with the external device. The generation section generates a session key according to the command which is received by the communication section and requires generation of a session key. The first record section stores the session key generated by the generation section. The erasure section erases the session key when a holding period of the session key stored in the first record section exceeds a threshold.

摘要： A portable electronic card system and a verifying method thereof are provided. The portable electronic card system includes: a portable personal electronic device, a rewritable card, and a writing device. The portable personal electronic device is used for obtaining a certificated code and a personal information from a remote controller. When a bidirectional verifying communication is performed between the remote controller and the portable electronic device to download the personal information, security code stored in the rewritable card be compared with security code stored in the portable electronic device for verifying and writing the personal information into the rewritable card, and another security code is generated to update or replace the original security code stored in the portable electronic device and the rewritable card.

摘要： Described is a technology, such as implemented in a computational software program, by which a minimal polynomial is efficiently determined for a radical expression over the ring Z of integer numbers or the ring Q of rational numbers. The levels of the radical are grouped into a level permutation group that is used to find a level permutation set. An annihilation polynomial is found based upon the level permutation set. The annihilation polynomial is factored, and a selection mechanism selects the minimal polynomial based upon the annihilation polynomial's factors.
