Patent number: 10310817Abstract: An apparatus and method for modular multiplication. The modular multiplication apparatus includes a first operation unit for performing a first operation based on a structure of at least one of a serial multiplier and a serial squarer-based multiplier; a second operation unit for performing a second operation based on a structure of at least one of the serial multiplier and the serial squarer-based multiplier; an adder unit for outputting the sum of results of the first operation and the second operation, inputting an intermediate value stream to the first input unit, which calculates the product of the intermediate value stream and a zeta parameter, and outputting a High-Order Term as a result of Montgomery Modular Multiplication, wherein the first and second operation units output a result in digit-serial format in order from the least significant digit to the most significant digit.Type: GrantFiled: November 9, 2017Date of Patent: June 4, 2019Assignee: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Yun-Koo Lee, Dong-Geon Lee, Min-Kyu Joo, Yoen-Cheol Lee, Sang-Woon Yang

Patent number: 10286004Abstract: Targeting-enhanced anticancer nanoparticles and preparation methods for the nanoparticles are provided. In particular, this invention provides targeting-enhanced anticancer nanoparticles comprising non-covalently bound anticancer drugs, serum albumins as the nanoparticle base material, and porphyrin compounds as tumor-targeting moieties. The targeting-enhanced anticancer nanoparticles described in the present invention are characterized by non-covalently bound constituents: anticancer drugs, serum albumin as the nanoparticle base material, and porphyrin compounds as tumor-targeting moieties, thus preventing common toxic side effects, enhancing the structural stability of nanoparticles, and enhancing tumor targeting by treatment with electromagnetic waves due to the activity of porphyrin, without structural and functional changes.Type: GrantFiled: April 7, 2017Date of Patent: May 14, 2019Assignee: JINIS CO., LTD.Inventors: Hyeon Jin Kim, Seong Tshool Hong, Hea Jong Chung, Min Kyu Joo, Hea Guk Cho, Jinny Hong

Patent number: 7885258Abstract: Disclosed is a packet switch equipment and a band control method using same. In accordance with one embodiment of the invention, a number of packets are sampled by using a packet sampling function provided by a packet switch chip, and the sampled packets are transmitted to a CPU. By using the transmitted sample packets, the total amount of bandwidth used by a corresponding user is estimated based on the source MAC address or the source IP address. If the estimated value exceeds a predetermined threshold, a bandwidth limitation function is applied to the user that is providing packets that exceed the bandwidth. A number of users can be dynamically recognized even when they are undefined, and a dynamic bandwidth limitation function is performed by tracking the bandwidth used by a corresponding user.Type: GrantFiled: December 12, 2006Date of Patent: February 8, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Min-Kyu Joo, Hoon-Jae Kim, Han-Seung Park, Seong-Ha Kim

Patent number: 7864782Abstract: In a packet processing apparatus and method in an ethernet switching system, an introduced packet is discarded by switching to a dummy port instead of trapping the packet until a layer 3 table of an ethernet switch chip is updated, thereby operating an Address Resolution Protocol (ARP) after having minimized a central processing unit (CPU) load. The packet processing apparatus, upon receipt of a first packet headed for a destination Internet protocol (IP) address not existing in the packet processing unit from a source host, transmits an ARP request packet to the destination IP address so as to acquire routing information of a destination host.Type: GrantFiled: September 19, 2006Date of Patent: January 4, 2011Assignee: Samsung Electronics Co., Ltd.Inventor: Min-Kyu Joo

Publication number: 20080170567Abstract: Disclosed is a packet switch apparatus applied to Internet Protocol (IP) network, the packet switch apparatus including: an Ethernet switch to perform packet switching, the Ethernet switch including a plurality of ports and a layer 3 table. The plurality of ports include a dummy port, which has an available port number allowing hardware-access, discards packets switched to the dummy port, and exists as a logical number, the layer 3 table storing Media Access Control (MAC) addresses corresponding to IP addresses of hosts and information about corresponding connection ports. A controller determines the nonexistence of the MAC address, virtually sets the MAC address corresponding to the destination IPv6 address, and updates the layer 3 table of the Ethernet switch chip as if the host of the set virtual MAC address were connected to the dummy port, when the MAC address corresponding to destination IPv6 address of the packet trapped by the Ethernet switch chip does not exist.Type: ApplicationFiled: January 15, 2008Publication date: July 17, 2008Inventor: Min-Kyu JOO
