Abstract: A method of extending message nodes of an Open Mobile Alliance (OMA)-Device Management (DM) protocol, which is performed by a server to improve efficiency of a vehicle over-the air (OTA) update, may comprise: receiving a package including vehicle device information (DevInfo) from a client of a vehicle; and checking an update state of software (SW) installed on the client on the basis of information having a field for defining information on a vehicle registration district, a field for defining information on a production year of the vehicle, and an SW field for defining an SW expansion which are included in the DevInfo.

Abstract: A computing resource management system using software modularization in a cluster computing environment in which computing devices are connected, including an application process running on each computing device and an algorithm processing process configured to run independently of the application process and perform task processing on the application process, the computing resource management system including: a task managing system configured to receive a task request message from an application process requiring a task from each computing device; a process managing system configured to confirm an algorithm processing process of computing devices connected to the cluster computing environment, and determine whether there is an algorithm processing process in an idle state to which the application process requested for a task will be assigned; and a performed managing system configured to confirm a result of an application process whose task is performed by the algorithm processing process.

Abstract: Disclosed is a user authentication-based packet classification method and apparatus for providing differentiated security services in a ship network. A user authentication-based packet classification method includes receiving an authorization code request message from a user terminal including a client, authenticating and authorizing a user of the client based on the authorization code request message, transmitting an authorization code response message to the user terminal in response to the authorization code request message, receiving an access token request message from the user terminal based on the authorization code response message, and transmitting an access token response message including an access token to the user terminal in response to the access token request message.

Abstract: Disclosed herein are a logical qubit execution apparatus and method. The logical qubit execution apparatus may be configured to execute, by a logical execution layer, a quantum circuit including requested logical qubits using a lattice surgery operation, generate, by the logical execution layer, measurement results of the logical qubits by combining measurement results of logical Pauli frames, generate, by a physical execution layer, a physical qubit circuit by converting a logical qubit operation corresponding to the measurement results of the logical qubits into a physical qubit operation, and measure, by the physical execution layer, results of an operation on physical Pauli frames by executing the physical qubit circuit.

Abstract: An encryption key management method includes: receiving a data registration request from a supplier terminal, determining a data identifier associated with the content data, encrypting a master key with a public key of the supplier terminal, and providing the supplier terminal with the master key encrypted with the public key of the supplier terminal, the data identifier, and a key update count value; receiving a subscription application related to the data identifier from a first subscriber terminal, encrypting the master key with a public key of the first subscriber terminal, and providing the first subscriber terminal with the master key encrypted with the public key of the first subscriber terminal and the key update count value; receiving encrypted content data encrypted with the symmetric key and a hash for the content data from the supplier terminal; and transmitting the encrypted content data and the hash to the first subscriber terminal.

Abstract: Disclosed herein is a method of preparing a deer bone extract in which deer bones are subjected to extraction at normal pressure and extraction under pressure to minimize decomposition of deer bone-derived gangliosides by heat and to increase protein extraction yield.
