Title: Authentication Method in Mobile Communication Environment
Inventor: KANG HYEONG U
IPC: H04W16/00
Filed: 2000-01-28
Abstract: PURPOSE: A subscriber authentication method in a mobile communication environment is provided to securely authenticate a subscriber without exposing a position and action of the subscriber by having a database for storing a secret key certificate of the opposite party, within each region certification server. CONSTITUTION: A VLR(Visiting Location Register) broadcasts the VLR and attempt value(r) to a terminal in its own region(1). A subscriber terminal transmits a secret key certificate(m11 x Ghh+e11) encoded using a secret key(KMUMU) and the r to an HLR(Home Location Register) and VKR(2). The VLR transmits a response value(m11 x Ghh+e11) which is a message for certificating MU and a response value(m22 x Ghh+e22) wherein the r is an attempt value, to the HLR(3). The HLR decodes the m11 x Ghh+e11 and m22 x Ghh+e22, extracts the KMUMU, and thereafter transmits a response value(m33 x Ghh+e33) to the VLR(4). The VLR certificates the HLR and certificates the subscriber MU through the HLR(5).

Abstract: Three genes encoding membrane-secreted proteins have been successfully isolated from osteoblast-like cell lines by using a method for specifically cloning membrane-secreted proteins. As the result of subsequent analysis on one of these genes, it has been found out that the protein encoded by this gene is a novel receptor protein which has an extracellular region alone, binds to cell membranes via a GPI anchor and carries therein a cysteine-rich repetitive region conserved in the TNF receptor super family. It has been also found out that when this protein is largely expressed in an osteoblast-like cell line, the proliferation of the cells are suppressed, the cells are morphologically changed, and the alkaline phosphatase activity which is one of the indications of the differentiation of osteoblasts is elevated.

Abstract: PURPOSE: An integrated circuit capacitor is provided to increase the capacitance of a capacitor without deteriorating the reliability of the capacitor by constituting a plug made of a metal of a main body section upwards extending in a trench and an anchor-shaped section being connected to the main body section and extending to an interconnection line under the anchor-shaped section. CONSTITUTION: A plug(32) made of an anchor-shaped metal has a main body section(34) extending to a trench(30) and an anchor-shaped section(22) being connected to the main body section(34) and extending to an interconnection line(26). The anchor-shaped section(22) has a broadened width section(23), and the plug(32) made of the anchor-shaped metal is engaged with the lower side section of the first dielectric layer(28). Since the plug(23) made of the anchor-shaped metal is formed in an anchor shape, the depth of the trench 30 can be formed in half or more the thickness of the first dielectric layer(28), and the plug(32) made of the anchor-shaped metal cannot be separated from the interconnection line(26) under the plug(32). Thus, since the depth of the trench(30) is increased, capacitance is augmented, and the reliability of the integrated circuit capacitor(20) is not deteriorated.
