    摘要: Provided are a method and an attestation system for preventing an attestation replay attack. The method for preventing an attestation replay attack in an attestation system including an attestation target system and an attestation request system, the method including: measuring associated components when an event that affects the integrity of the attestation target system occurs; perceiving own identity information and verifying the perceived identity information; extending the measured component and the identity information into a register and logging the measured component and the identity information; generating an attestation response message including values of the log and the register when an attestation request message is received from the attestation request system; and transmitting the generated attestation response message to the attestation request system. Therefore, the method and an attestation system may be useful to provide an additional simple mathematical operation in verifying an attestation message by preventing an attestation replay attack, and thus to minimize performance degradation in the attestation system, compared to the conventional attestation processing mechanisms.

    摘要: A security management server includes an input unit for receiving image data from at least one network camera; a control unit for assigning an access authority level to each image data received via the input unit; and a storage unit for storing therein the image data along with the access authority levels assigned by the control unit. When receiving a request for a specific image data among the image data stored in the storage unit from a user having a user access authority level, the control unit compares the user access authority level and the access authority level assigned to the specific image data, and based on comparison result thereof, selectively provides the specific image data to the user.

    摘要: The present invention provides a global navigation satellite system (GNSS) based positioning system and tracking method using a data communication network. When a GNSS-based positioning device is connected to a data communication network, the positioning device transfers the GNSS digital data and supplementary information used for additional performance improvement to a location tracking server through the data communication network, the location tracking server calculates a position of the positioning device with improved receiver sensitivity based on plentiful computational resources available at the location tracking server. Thus, the positioning device may find its location of even in very poor signal condition. Further, the present invention provides a positioning system and method using a data communication network, which may achieve time synchronization when there is a need to extract not only position information but also absolute timing information.
