Title: Network Security Method in Layer 2
Inventor: LEE BAEK JU
IPC: H04L12/22
Filed: 2000-11-22
Abstract: PURPOSE: A method for securing a network in a layer 2 is provided to perform various controlling operations for a security and control unauthorized users, who asses a network service, selectively. CONSTITUTION: If a packet is entered to an Ethernet device, it is judged whether an MAC(Medium Access Control) address corresponded to the packet exists in an MAC address table(S401). If the MAC address does not exist in an MAC address table, the MAC address is recorded in the MAC address table(S402). It is judged whether a stable mode of a system is activated or not(S403). If a stable mode of a system is not activated, new MAC address is removed(S404). In case that a stable mode is activated(S405), a manager selects a processing method with respect to a terminal which is not permitted(S407). In case that a limit mode is selected, a threshold capable of being introducing to a port is inputted(S406), the manager selects a processing method with respect to a terminal which is not permitted(S407). In case that a stable mode is activated, it is judged as to a limit mode(S408). In the case of not a limit mode, a service is not provided because a service can be provided to only currently accessed terminal. In case that the manager selects a method for preventing a port(S413), accesses of all terminals are prevented by preventing a port of the Ethernet device(S412).

Abstract: PURPOSE: An application service system and its method through remote control of application service are provided to prevent copy-protection of an application, and to increase the number of a formal user by enabling a general user to use the application by means of a small amount of money, and to produce software goods which have never been made by a unit package before by renting the application. CONSTITUTION: A software development company inserts a lock library to a general application to a normal execution routine for an interlock with a middleware. In case that there is no library, the library is damaged or a lock code in the library isn't be opened, the application is made to be unexecutable. A general user connects to an internet site which provides a rental application. The user receives the rental application and applies the rental application through all sorts of media. The user receives the middleware program, "GORI" and installs the rental application. The first key code written in cipher is automatically compared with an inner value of the lock library. In case that the value is "true", the first key code have a state of "execution control lock device opened" for the application execution. A rental application execution routine reads the lock library. In case that the lock library have the sate of the "execution control lock device opened", the rental application is normally executed. In case that the library have a state of "execution control lock device closed", the execution is rejected. A code certification processing server gets permission to provide a code. The server registers a record on a client's use to a database as a log file and is endowed with the second key code from the middleware("GORI") just before 10 seconds after the registration. The rental application continues to be used. In case that the general user terminates the rental application, the middleware is separated from the first key code in the lock library. The rental application is terminated.
