An electronic device includes a peripheral device, a processor, an interrupt controller configured to manage interrupts generated by the peripheral device and the processor on the basis of a register, and a virtualizer, wherein the virtualizer may be configured to virtualize a portion of the processor and a portion of the at least one peripheral device to generate a first partition, generate first interrupt information corresponding to an interrupt usable in the first partition, generate first processor information corresponding to a portion of the processor usable in the first partition, check whether a configuration of the register is related to at least one of the first interrupt information and the first processor information when the register is configured by the first partition, and allow the configuration of the register when the configuration of the register is related to the at least one information.

Electronic device, interrupt configuration control method, and storage medium

Disclosed is a system for performing key management of an in-vehicle network. The key management system of the in-vehicle network includes a reception unit configured to receive a shared secret key of a central gateway and a domain gateway, a memory configured to store a program for performing key management of the in-vehicle network using the shared secret key, and a processor configured to execute the program. The processor generates a secret key to be stored in a node of the in-vehicle network using the shared secret key and a unique ID of the node.

System for key control for in-vehicle network

Provided is a method of updating an integrity check value (ICV) stored in a hardware security module (HSM). The method includes storing user authentication information of the terminal transferred from the terminal to preregister a user of the terminal, transferring an authentication information request message, requesting the user authentication information, to the terminal in response to an update request message which is transferred from the terminal and includes an update value of the ICV, comparing the user authentication information transferred from the terminal with the stored user authentication information to perform an authentication operation on the user of the terminal according to the authentication information request message; and when the user of the terminal is successfully authenticated, updating the stored ICV by using the update value.

Hardware security module, method of updating integrity check value stored in hardware security module, and method of updating program stored in terminal by using hardware security module

An apparatus for providing near field communication (NFC) for a mobile device, includes a USB (universal serial bus) signal processing unit configured to convert a signal of the mobile device, which is received through a USB interface into a value to be processed in a central processing unit, and convert a value received from the central processing unit into a signal to be transmitted to the USB interface. Further, the apparatus includes an analog signal processing unit configured to convert an analog signal received from an outside device into a digital signal, and convert a digital signal of the central processing unit into an analog signal to transmit the converted analog signal to the antenna.

Apparatus and method for providing near field communication for mobile device

A method for sharing and updating a key using a watermark is disclosed. The method includes receiving an image to be encoded from an image input device encoding the image, and inserting a master key value as a watermark into the encoded image, for use as an input of a key derivation function.

Method for sharing and updating key using watermark

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.

Security management server and image data managing method thereof

An apparatus for hash cryptography has a hardware structure that is capable of providing both secure hash algorithm (SHA)-1 hash calculation and SHA-256 hash calculation. The apparatus for hash cryptography generates a plurality of first message data corresponding to a plurality of first rounds when the SHA-1 hash calculation is performed and generates a plurality of second message data corresponding to a plurality of second rounds when the SHA-256 hash calculation is performed by using one memory, one first register, one XOR calculator, and one OR calculator, calculates a message digest by the SHA-1 hash calculation by using the plurality of first message data when the SHA-1 hash calculation is performed, and calculates a message digest by the SHA-256 by using the plurality of second message data when the SHA-256 hash calculation is performed.
