Abstract: Exemplary embodiments of the present invention relate to a batch verification method for verifying a plurality of authentication data or digital signature values and an apparatus thereof. A batch verification method according to an embodiment of the present invention comprises: rearranging N pairs of individual instances which compose a batch verification instance; selecting N−1 verification exponents from a verification exponent set E which is used for the batch verification; and performing the batch verification for the rearranged batch verification instance by using the selected verification exponents. Exemplary embodiments of the present invention can be suitable for digital signature and cryptographic confirmation. According to exemplary embodiments, verification computation amount of a plurality of authentication data or digital signature values can be significantly reduced.

Abstract: The present invention relates to an apparatus and method that control a vessel deviating from an anchorage using wide-range sensor-based spherical trigonometry. In the method, vessels anchored in an anchorage are monitored. The anchorage is defined as a group, and the group of the anchored vessels is managed. Leaving of a vessel, needing to deviate from the anchorage, from the group is controlled. If a vessel recognized as a vessel identical to one that left the group requests anchoring after a predetermined period of time has elapsed, the anchoring-requesting vessel is controlled.

Abstract: Disclosed herein are a universal subscriber identification module card and a communication method using the same. The universal subscriber identification module card includes a Universal Subscriber Identification Module (USIM) chip, a pad, and a security chip. The USIM chip performs the user authentication of a mobile terminal. The pad electrically connects the USIM chip to the mobile terminal when the USIM chip is inserted into the mobile terminal. The security chip performs a security function for the mobile terminal independently of the USIM chip and shares the two power terminals of the pad with the USIM chip.
