Disclosed is a composition for forming a dielectric, which is applied to an embedded capacitor with a high dielectric constant, a capacitor produced using the composition, and a PCB provided with the capacitor. The composition includes 40 to 99 vol % of thermoplastic or thermosetting resin, and 1 to 60 vol % of semiconductive filler. Alternatively, the composition includes 40 to 95 vol % of thermoplastic or thermosetting resin, and 5 to 60 vol % of semiconductive ferroelectric substance. Furthermore, the present invention provides the capacitor, produced using the composition, and the PCB provided with the capacitor. Therefore, the dielectric, which is produced using the composition including the semiconductive filler or semiconductive ferroelectric substance, is advantageous in that the dielectric constant is high and a dielectric loss is low. The dielectric is usefully applied to produce an embedded capacitor with the high dielectric constant and the PCB provided with the embedded capacitor.

Provided are a security router system for a network and a method of authenticating a user who connects to the system. The security routing system includes: a plurality of physical link ports inputting/outputting packets; a physical layer matching unit transmitting/receiving packets to the physical link ports and generating a media access control (MAC) frame; and a network processor including routing processing means that establishes a transport route for input packets via the physical layer matching unit and processes routing protocols, packet forwarding means that forward the input packets to their destinations, intrusion detection means that classify the input packets based on a packet classification standard and determine whether the input packets are attacks from outside, and user authentication means that determine whether a user is authorized to connect to a router, thereby reducing expenses required to build a network while maintaining security in comparison with a conventional firewall or intrusion detection system, and increasing reliability and safety of the network by preventing harmful traffic since each router performs a network security function.

Provided are a method and apparatus for providing a security mechanism guaranteeing transparency at a transport layer. The method includes: receiving a data packet from an application program, and searching key information corresponding to the data packet in key information database; determining whether to request a key exchange module of an application layer for a new key negotiation according to a result obtained by searching key information; and performing encrypting/decrypting based on key information when the key exchange module stores key negotiation information obtained by the new key negotiation in a kernel. The apparatus encrypts/decrypts the data packet at the transport layer of the kernel, thereby providing the application program with security transparency, effectively controlling and making it easily expansible.
摘要:
Disclosed herein is a linear compressor in which a bonding position of a muffler can be accurately determined when the muffler is bonded to a fixing plate so that a center axis of a discharge spring casing formed at the muffler accurately coincides with a center axis of an insertion hole formed at the fixing plate. This enables a discharge valve to be concentrically mounted to a cylinder, thereby eliminating the risk of slight leakage or malfunction of the discharge valve due to eccentric arrangement of the discharge valve and the cylinder.

Disclosed herein is a muffler of a linear compressor. In the present invention, a center of an entry pipe of the muffler is in line with that of an inhale port of a piston. Therefore, a flow loss occurred when fluid is inhaled into the inhale port from the entry pipe can be reduced, and inhale efficiency can be improved. Furthermore, the plurality of inhale ports is eccentrically disposed in a front of the piston, and each center of the plurality of entry pipes is formed to be in line with that of the inhale ports. Not only the center but also the number of the inhale port and the entry pipe are agreed, on this account, the flow loss can be decreased and the inhale volume can be increased.
