  • Patent number: 9525556
    Abstract: A method for issuing a certificate signing request (CSR) certificate in a vehicle-to-anything (V2X) communication environment includes: receiving, at a first server, a certificate issuance request message including vehicle identification information transmitted from a communication module of the vehicle; determining, by a second server, whether a CSR certificate corresponding to the vehicle identification information has already been issued with reference to a database; and determining, by the second server, whether to issue the corresponding CSR certificate or whether to generate an error message, based on the determination of whether the corresponding CSR certificate has already been issued.

  • Publication number: 20160119151
    Abstract: A method for issuing a reliable certificate to a vehicle for a vehicle-to-anything (V2X) communication in a server on a network comprises receiving a certificate issue request including vehicle identification information and road-side unit (RSU) identification information from an RSU. Log information for the certificate issue request is extracted from a database. Normality or abnormality is determined according to whether a predetermined certificate issue criteria is satisfied by analyzing the certificate issue request and the log information. The certificate is issued and the certificate is transmitted to a vehicle communication module according to determination of normality, or certificate revocation information is registered according to determination of abnormality.

  • Patent number: 9271245
    Abstract: There is a provided a method for deciding transmission power in order to transmit at least one of secret data and non-secret data. The method may comprise: determining whether data to be transmitted by a transmitting device is sensitive to a delay; determining whether both the secret data and the non-secret data are required to be simultaneously transmitted when the data to be transmitted is sensitive to the delay; and applying different weights to the secret data and the non-secret data and deciding transmission power to maximize a total channel capacity according to the application, when it is determined that both the secret data and the non-secret data are required to be transmitted.

  • Patent number: 9148780
    Abstract: A method and apparatus for secured data transmission is provided. The base station determines a first precoding matrix based on channel information of an eavesdropper. The base station determines a second precoding matrix and a third precoding matrix. The base station generates the secure data by precoding first user data for a target user with the first precoding matrix and the second precoding matrix. The base station transmits the secure data signal to the target user. The second precoding matrix is determined based on the first precoding matrix and the first channel information. The third precoding matrix is determined based on the first channel information and the second channel information.

  • Publication number: 20110098574
    Abstract: A patient position monitoring apparatus capable of monitoring the position of a patient is provided. The patient position monitoring apparatus includes a position guider emitting a source and a plurality of guide markers sensing the source emitted from the position guider and transmitting sensed information to the position guider. The position guider determines whether positions of the guide markers are changed through the sensed information. When the position of the patient is changed, and thus the source emitted from the position guider is out of the range of the guide markers, a warning signal is output. Accordingly, a user can monitor a variation in the position of the patient even if the user does not continuously observe the patient.
