    摘要: 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: 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.

    摘要: The present invention relates to a method for producing (meth)acrylic acid comprising a process of recovering (meth)acrylic acid as an aqueous (meth)acrylic acid from a (meth)acrylic acid-containing gas mixture produced by the catalytic gas phase oxidation of at least one reactant selected from the group consisting of propane, propylene, isobutylene and (meth)acrolein, and a system usable for the method. The recovery process comprises the steps of: (1) feeding the (meth)acrylic acid-containing gas mixture into a quenching tower and condensing it in the quenching tower so as to recover an aqueous (meth)acrylic acid solution from the bottom of the quenching tower, in which some of the recovered aqueous solution of (meth)acrylic acid is recycled to the top part of the quenching tower so as to condense the (meth)acrylic acid-containing gas mixture; (2) passing the uncondensed part of the (meth)acrylic acid-containing gas mixture from the quenching tower through the top of the quenching tower to an absorption column; (3) absorbing (meth)acrylic acid contained in the uncondensed part of the (meth)acrylic acid-containing gas mixture in the absorption column with a absorption solvent; (4) feeding the (meth)acrylic acid solution resulting from the absorption in the step (3) to a desorption column; and (5) separating the solvent used in the step (3) from the (meth)acrylic acid solution in the desorption column, so that the substance from which the solvent has been removed in the desorption column is fed to the quenching tower, and the separated solvent is recycled to the absorption column. The inventive method is an efficient and economic method which allows a reduction in energy consumption in subsequent purification processes by maximizing the concentration of an aqueous solution of (meth)acrylic solution recovered at the bottom of the quenching tower and minimizing the concentration of (meth)acrylic acid lost from the vent gas of the absorption column.

    摘要: The present invention relates to a method for providing an arbitrary sound chosen by a called subscriber for a caller instead of a conventional RBT (RingBack Tone). The present method comprises: the first step, conducted by an HLR (Home Location Register), of furnishing a call-originating exchanger with information on whether to replace RBT or not for a terminal if a location request message is received from the call-originating exchanger when a call connection is requested to the terminal; the second step, conducted by the call-originating exchanger, of requesting a trunk connection to a call-terminating exchanger, and further requesting another trunk connection to a sound providing means based on the information and preset routing information while furnishing the sound providing means with information to identify the terminal; and the third step, conducted by the sound providing means, of selecting a sound based on the terminal identifying information, and providing the selected sound for a caller instead of an RBT.

    摘要: The present invention relates to method and apparatus for providing an arbitrary sound chosen by a called subscriber instead of ringback tone to a calling subscriber. In this present invention, if a call is received, a terminating exchanger requests a trunk connection to a sound db server based on the first information on whether or not to replace a ringback tone and the second information on a route to the sound db server that are received from a home location register (HLR), and provides a called subscriber identification for the sound server. Then, the sound db server searches its db for a sound specified by the called, and provides the found sound for the caller instead of a conventional ringback tone via the terminating exchanger connected through a trunk. Through this sequential procedure of network elements, a caller can hear a sound specified by a called instead of a dry ringback tone.

    摘要: Provided is a method of generating and searching for a single ternary content addressable memory (TCAM) entry for range search and exact-match search. First, it is determined whether an entry to be added is a range search entry or an exact-match search entry. When the entry is the range search entry, a bit at a predetermined position in the upper m bits corresponding to a range represented by the entry is set to “1” and the remaining bits including lower n bits is set to a “don't care” bit x, based on a range table for representing position information of one of the upper m bits which is set to “1” in ranges. When the entry is the exact-match search entry, the upper m bits is set to “don't care” bit x and the lower n bits is set to the entry value. By generating and searching for a single TCAM entry for a range search and an exact-match search, a space for storing the TCAM entry can be optimized and efficiency thereof can be improved.

    摘要: The present invention presents a method for providing the location information of a mobile station(MS) by selectively using a DBM-based method and a TCP/IP-based method on a global positioning system(GPS) in a mobile telecommunication network constituted of a client server, a mobile positioning center(MPC), a home location register(HLR), and a position determination Entity(PDE). By selectively using a DBM-based method or a TCP/IP-based method according to the type of requested service, the present invention enables to reduce the time required for obtaining the accurate location. Moreover, it can provide the requested location based service(LBS) on an MS even when the MS is on-line or on stand-by mode.
