20110092152 | WIRELESS COMMUNICATION SYSTEM FOR CONTROLLING COMMUNICATION AREA BY JAMMING - A wireless communication system for geographically controlling a communication area includes an access point for communicating with a terminal in a first area, and a jammer for generating noise for intercepting communication between the access point and a terminal in a second area. A jamming boundary for dividing an area in which the terminal can communicate with the access point and an area in which the terminal cannot communicate with the access point in an area in which the first area and the second area are overlapped is formed, and the jamming boundary is formed by a ratio between power of a signal transmitted to the terminal by the access point and power of a signal of the noise. | 04-21-2011 |
20100150104 | DEEP PACKET INSPECTION DEVICE AND METHOD - The present invention relates to a deep packet inspection method and device of a wireless communication system. The deep packet inspection method includes: receiving a first deep packet inspection result for a packet of a terminal from a first subnet before a handover when the handover occurs; receiving a second deep packet inspection result for the packet of the terminal from a second subnet after the handover; and coordinating the first deep packet inspection result and the second deep packet inspection result when the handover occurs. | 06-17-2010 |
20100144035 | Delivery system for nucleic acids using cationic polymer conjugates - The present invention relates to a delivery system for nucleic acid using a cationic polymer conjugate, and more specifically relates to a delivery system for nucleic acid comprising a cationic polymer conjugate prepared by conjugating hyaluronic acid or its derivative and polyethyleneimine, and a composition of delivering a nucleic acid into mammalian cell comprising a complex of the nucleic acid and a cationic polymer conjugate with electrostatic binding. | 06-10-2010 |
20100115618 | METHOD AND DEVICE FOR DETECTING UNKNOWN NETWORK WORMS - A method and device for detecting a network worm on the network allows early detection of an unknown network worm with less computational quantity based on a change of randomness occurring to network traffic without using a pattern-matching-based worm detecting method or a behavior-based worm detecting method. | 05-06-2010 |
20080205644 | Method for encrypting and decrypting an image frame - An apparatus for encrypting an image frame generates a key frame, performs XOR with the image frame and the key frame to generate a temporary image frame, and changes positions of blocks of the temporary image frame according to a first key to generate an encrypted image frame. | 08-28-2008 |
