범용 가입자 식별 모듈 카드 및 이를 이용한 방법이 개시된다. 본 발명에 따른 범용 가입자 식별 모듈 카드는 모바일 단말의 사용자 인증을 위한 유심칩; 유심칩이 모바일 단말에 삽입되어 모바일 단말과 전기적으로 연결되도록 하기 위한 패드; 모바일 단말에 보안 기능을 수행하고 모바일 단말에서 제공하는 두 개의 전원 단자를 유심칩과 공통으로 사용하는 보안용칩을 포함한다. 유심칩과 보안용칩이 다른 인터페이스를 사용하여 사용자 인증 기능과 보안 기능을 독립적으로 수행함으로써 모바일 단말에서 유심칩과 보안용칩을 효율적으로 사용할 수 있다.
Abstract:
According to the present invention, a user authentication method using a security keypad based on an image may comprise the steps of generating the security keypad on which the image is randomly disposed when an application mounted on a smart device is executed, wherein an MTM contains at least one of letters, numbers, and symbols for the image; displaying the generated security keypad to a display panel of the smart device; transmitting an input password to the MTM if the password is inputted through the security keypad; performing user authentication using the comparison of the input password and a conventional stored password by the MTM; and outputting the execution result of the user authentication to the display panel by the MTM.
Abstract:
A universal subscriber identification module card and a method using the same are disclosed. The universal subscriber identification module card according to the present invention comprises; a USIM chip for user identification of a mobile terminal; a pad makes the USIM chip be inserted into the mobile terminal and be electrically connected to the mobile terminal; and a chip for security which performs a security function in the mobile terminal and use two power terminals provided from the mobile terminal with the USIM chip in common. The USIM chip and the chip for security use different interface and independently perform a user identification function and a security function, therefore the USIM chip and the chip for security are effectively used in the mobile terminal. [Reference numerals] (100) Universal subscriber identification module card; (110) USIM chip; (120) Chip for security
Abstract:
PURPOSE: A security function providing apparatus capable of using the guest operating system at the virtualization computing system is provided to provide the execution and internal data of important software to the computing environment which is exclusively operated in a separate virtual machine by using the virtualization technology. CONSTITUTION: A host operating system (220) has an open type execution environment which executes the security program. A guest operating system (250) has the exclusive type execution environment which executes a back-end security service on a virtual machine which is provided by the hypervisor on the host operating system. A back-end security service (260) which is operated in the host operating system and a security program (270) which is executed on the guest operating system are executed on a virtually different physical space.

Abstract:
PURPOSE: A method for providing a safe execution environment based on domain separation and a device thereof are provided to improve security for software executed in a terminal by composing two independent execution environments through virtualization-based domain separation and providing a safety service through a security service channel between domains. CONSTITUTION: A general service domain(300) performs operation requested for a general service in a mobile terminal. A safe service domain(400) is separated from the general service domain based on virtualization to perform operation requested for a security service. The general service domain includes a general service application(360) for interlinking the security service, a safe service API(Application Program Interface)(350) for interlinking the security service requested in the general service application with the safe service domain, and a front end driver(340) for executing the security service received from the API by transmitting the service to the safe service domain.
