摘要： A solenoid valve for a brake system, which has a simple constitution and can be easily manufactured with reduced manufacturing costs, is disclosed. A valve core is formed in a cylindrical shape, and has a through-hole formed in a longitudinal direction of the valve core and a fluid passage formed in a radial direction of the valve core so as to communicate with the through-hole. A sleeve is coupled to an outer surface of the valve core. The sleeve has a dome-shaped shielding portion at one end, and a flange portion to be fixed to a modulator block at the other end. An armature is slidably mounted in the sleeve. An exciting coil is provided to move the armature. A valve seat is fixed in the valve core, and has a first orifice. A plunger is mounted in the valve core. The plunger moves by movement of the armature to open or close the first orifice. A restoring spring is provided to press the plunger toward the armature.

摘要： A security USB connector implements an intrusion prevention function preventing the propagation of malicious codes to a host terminal from a USB device while minimizing host terminal resource consumption, and an intrusion prevention system using the same are disclosed. A security USB connector is positioned between the host terminal supporting a USB host and a USB device, and a security inspection is performed on data transferred from the USB device to the host terminal through the security USB connector. Also, a host terminal without an intrusion prevention function can prevent an intrusion by using the portable security USB connector.

摘要： An adaptive security policy based scalable video service apparatus includes a video streaming server, an adaptive security policy server and a terminal. The video streaming server receives a service demand via a network and generates an encrypted streaming data. The adaptive security policy server analyzes a media structure and the service demand, by using a service profile received from the video streaming server, so as to generate a security policy description. The terminal generates and transmits the service demand to the video streaming server or the adaptive security server, obtains the encrypted streaming data from the video streaming server and decrypts the encrypted streaming data for playback, storing and retransmission.

摘要： Provided are a system and method for coping with encrypted harmful traffic in hybrid IPv4/IPv6 networks. The system includes: an encryption key manager collecting encryption key information from a user terminal connected to the hybrid IPv4/IPv6 networks, and storing and managing the information in an encryption key database; an encryption traffic collector collecting encrypted traffic from traffic in the hybrid IPv4/IPv6 networks; an encryption key searcher searching for an encryption key used to decrypt the encrypted traffic from the encryption key database using a source IP address and a destination IP address of the encrypted traffic; a harmful traffic determiner decrypting the encrypted traffic using the encryption key and determining whether the decrypted traffic is harmful traffic; and an encryption traffic processor, if the decrypted traffic is determined to be harmful traffic, blocking the harmful traffic and, if the decrypted traffic is determined to be normal traffic, encrypting the normal traffic, and transferring the encrypted traffic to a user terminal corresponding to the destination IP address, thereby detecting and blocking an attack pattern using the encrypted harmful traffic in hybrid IPv4/IPv6 networks which cannot be detected by a conventional firewall system and more effectively protecting the networks.
