The present invention relates to a pharmaceutical composition and a food composition containingHook. extract or a fraction thereof as an active ingredient for preventing, treating or ameliorating neuroinflammation or neuro-degenerative diseases. TheHook. extract or a fraction thereof according to the present invention is derived from a natural product which has been in use as a natural medicinal ingredient, and as such, has no side effects and inhibits expression of NO, PGE, iNOS and/or COX-2 genes or protein, which are factors associated with inflammation, and is additionally superbly effective for increasing and improving memory and the ability to learn, and thus can be beneficially used to prevent or treat neuroinflammation or neuro-degenerative diseases.

Method for treating neuroinflammation with a pharmaceutical composition containinghook. extract or fraction thereof as active ingredient

A method authenticates a group driving service of a moving object. The method includes authenticating the moving object when an authentication request for the registration of the group driving service is received from the moving object, generating a certain group having group driving service registration information based on group driving registration information when a registration request for the group driving service is received from the moving object, the registration request including the group driving registration information, and transmitting the group driving service registration information of the certain group to the moving object.

Method and apparatus for authenticating group driving of moving object

An authentication apparatus for detecting and preventing a source address spoofing packet, includes a packet reception unit configured to receive a packet from a previous node or a user host; a self-assurance type ID generation unit configured to generate a self-assurance type ID of a source node of the received packet; and a self-assurance type ID verification unit configured to determine whether the source address of the received packet has been spoofed. Further, the authentication apparatus includes a white list storage unit configured to store a reliable source node; a black list storage unit configured to store an unreliable source node; and a packet transmission unit configured to transmit the packet whose source has been verified through the self-assurance type ID verification unit to a next network node.

Disclosed herein is a method of verifying key validity and a server for performing the method. The method is configured such that a service provision server verifies key validity in an anonymous service for providing local linkability. The service provision server receives a revocation list. A local revocation list is generated using the received revocation list and a secret key. A virtual index of a service user required to verify key validity is calculated. Whether a key of the service user is valid is verified, based on whether the virtual index is included in the local revocation list.
