  • Patent number: 11347837
    Abstract: A method for enhancing the security of a vehicle controller includes: performing, by a microcontroller, a secure boot when a vehicle controller is powered on and booted; determining, by the microcontroller, whether the secure boot is for a reprogramming mode or an other operation mode, among a plurality of operation modes of the vehicle controller, when the secure boot is completed; performing, by the microcontroller, a password input step, generating an error password, and automatically inputting the error password when the secure boot is for an operation mode other than the reprogramming mode from the plurality of operation modes of the vehicle controller; and jumping, by the microcontroller, to a main software (SW) routine immediately when the error password is inputted.

  • Patent number: 10614220
    Abstract: The present invention relates to a system and a method for secure boot of an engine management system, in which the system for secure boot of an engine management system, comprises a memory in which a boot code and at least one application are stored, a host CPU for sending a start-up command to a hardware security module HSM when a start-on or reset event occurs, and transmitting a remaining memory area authentication command to the HSM after executing the boot code when boot code authentication success is received from the HSM, and the HSM for starting up and performing authentication of the boot code stored in the memory as the start-up command is received, sending a boot code authentication result to the host CPU, and performing authentication of the rest of the memory excluding the boot code when the remaining memory area authentication command is received.

  • Patent number: 9877922
    Abstract: Disclosed is a process of preparing sustained release microspheres, containing a biodegradable polymer as a carrier and a drug, using spray drying. The process comprises preparing a solution, suspension or emulsion containing a biodegradable polymer, a drug and a solvent; spray drying the solution, suspension or emulsion; and suspending spray-dried microspheres in an aqueous solution containing polyvinyl alcohol to remove the residual solvent and increase the hydrophilicity of the microsphere surface. The process enables the preparation of microspheres having high drug encapsulation efficiency, almost not having a toxicity problem due to the residual solvent, and having good syringeability. The microspheres prepared according to the present invention release an effective concentration of a drug in a sustained manner for a predetermined period when administered to the body, and are thus useful in the treatment of diseases.

  • 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: 9121815
    Abstract: Disclosed is a method for measuring a fiber content of polyethyleneterephthalate (PET) and polytrimethyleneterephthalate (PTT) fibers, particularly wherein the method includes: a qualitative analysis step of identifying a presence of polyethyleneterephthalate (PET) and polytrimethyleneterephthalate (PTT) fibers in a mixed-spun fiber product; and a quantitative analysis step of measuring the fiber content by a microscopic count through difference in color between PET and PTT fibers by birefringence in a cross polarization state of a polarized light microscope (PLM). Through the present invention, it is possible to simply and accurately calculate the fiber content of PET and PTT fibers in a mixed-spun fiber material in which various kinds of fibers are mixed.
