Abstract:
PURPOSE: An electronic finance transaction method using a token and system thereof are provided to accurately control currency by realizing a safe and convenient currency system. CONSTITUTION: One or more terminals transmit first information including money to a financial transaction server in a first terminal and a second terminal(S410). The second terminal transmits second information to the finance transaction server(S420). The second information displays a first token which is connected to the second terminal by separating the first token from the first terminal. After the financial transaction server receives the second information, the money is transferred from a first account to a second account according to the first information(S430, S440).
Abstract:
PURPOSE: A code converting device for execution program analysis and an apparatus thereof are provided to repetitively execute a deformation code while deleting a part of the execution code by stage or replacing the part with the other code even when only an execution code and a manual are given. CONSTITUTION: A division unit(110) divides an execution program into two or more codes. A code deformation unit(120) decides an exclusion code excluded from replacement or deletion targets of the execution program. A deformation code execution unit(130) obtains an execution result through the execution of the deformation code. Based on the execution result, a positioning unit(140) decides the location of a target code within the execution program.

PURPOSE: An elliptic curve cryptography system based on a real domain and a method thereof are provided to generate a public key based on a real number system. CONSTITUTION: In an elliptic curve cryptography system based on a real domain and a method thereof, selectors(11-1) select at least one point on an elliptic curve which is defines as a finite field. Public key parts(11-3) generate a public key by using elliptic equations defining an elliptic curve and characteristic equation and generate a public key.

가상화 환경에서의 대역폭 할당 방법 및 장치가 개시된다. 본 발명에 따른 가상화 환경에서 수행되는 대역폭 할당 방법으로, 가상화 환경에 포함된 복수의 가상 머신으로부터 디스크의 대역폭 사용 요청을 수신하는 단계, 수신된 디스크 대역폭의 사용 요청에 대한 간헐성을 감지하는 단계, 감지된 간헐성을 기반으로 복수의 가상 머신 중 적어도 하나의 가상 머신에 미리 설정된 시간 단위로 디스크의 대역폭을 할당하는 단계를 포함한다. 본 발명에 의하면 가상화 환경에서 가상 머신이 디스크 대역폭을 효과적으로 사용 가능하다.
Abstract:
PURPOSE: A data delivery method between virtual machines using a shared memory and a user terminal including a data delivery function between the virtual machines are provided to omit an unnecessary data transmission process by providing a memory shared between virtual machines. CONSTITUTION: First and second VM(Virtual Machine) modules(111,112) are installed in a system memory of a user terminal and a process chip(A) senses a network protocol signal according to communication between the first and the second VM modules. The processor chip converts the network protocol signal into operation on a memory bus to generate operation related to memory bus. A memory chip(B) receives the operation related to memory bus to process communication between the first and the second VM modules. [Reference numerals] (110) Virtual machine unit; (111) First virtual machine module; (111a) First I/O port; (112) Second virtual machine module; (112a) Second I/O port; (120) Mother board; (121) Process unit; (130) Memory; (A) Processor chip; (B) Memory chip
