Patent number: 9015826Abstract: A mobile platform security apparatus and method is provided. The apparatus may perform a security setting by generating a first authentication key, a second authentication key, and a third authentication key for each function called by an application program. The apparatus may store the first authentication key and an identifier for identifying the application program in a first storage unit, the second authentication key and the identifier in a secret domain of a second storage unit, and register the third authentication key and the identifier as a function parameter in the application program. Subsequently, if the function is called by the application program, the apparatus may determine values for the first authentication key, the second authentication key, and the third authentication key corresponding to the called function, and may perform authentication processing using the three authentication key values.Type: GrantFiled: September 16, 2011Date of Patent: April 21, 2015Assignee: Pantech Co., Ltd.Inventor: Jae Choon Park

Patent number: 8955056Abstract: A terminal to assign permission to an application includes a storage device to store an application list including information of applications authorized to receive manager permission, and an application processor to receive a request for the manager permission from the application and to determine to allow the manager permission to the application in response to a determination that the application is included in the application list. A method that uses a processor to assign permission to an application includes receiving a request for manager permission from the application, determining, using the processor, whether the application is included in an application list including information of applications authorized to receive manager permission, and determining whether to allow the manager permission to the application if the application is included in the application list.Type: GrantFiled: October 16, 2012Date of Patent: February 10, 2015Assignee: Pantech Co., Ltd.Inventors: Suk Woon Choi, Jae Choon Park

Patent number: 8601599Abstract: A platform security apparatus and a method thereof are capable of protecting a mobile communication terminal from an abnormal or unintended operation of an application program installed over a platform of the mobile communication terminal. An authentication key is created with respect to each function of an application program, and the authentication key and an identifier of the application program are associated with each other and stored. An authentication process is performed by comparing an authentication key and an identifier of an application program registered as function parameters with an authentication key and an identifier of the application program which have been stored, when the application program calls the function.Type: GrantFiled: August 9, 2010Date of Patent: December 3, 2013Assignee: Pantech Co., Ltd.Inventor: Jae-choon Park
