Abstract: Disclosed herein are a method and apparatus for generating a dynamic security module which is allocated to a user terminal so that code configured to be executed on the user terminal for security varies with execution time. The method includes allocating a predetermined value to at least one of variables as which parts or all of variable portions of code constituting a dynamic security module have been designated. Part or all of the code constituting the dynamic security module transmitted to a user terminal has a predetermined valid period.

Abstract: Disclosed herein are a dynamic security module server device for transmitting a dynamic security module to a user terminal and receiving a security management event from the user terminal, and a method of operating the dynamic security module server device. The dynamic security module server device includes a communication unit configured to transmit and receive a security management event over a network, and a processor configured to control the communication unit. The processor is configured to create a security session with the security client of a user terminal, and to transmit a dynamic security module to the security client of the user terminal so that part or all of code performing security management in the security client of the user terminal in which the security session has been created has a predetermined valid period.

Abstract: A method of processing data for paying for at least one of item in a system having a Payment Gateway server and a mobile device is disclosed. The method includes steps of downloading an application by using address information in a memory of the mobile device, transmitting user information stored in the USIM of the mobile device to the PG server if the first phone number is identical with the second phone number, generating ID information for the user in the PG server, transmitting first barcode from the PG server to the mobile device if the mobile device requests a barcode to the PG server, transmitting request signal for second barcode from the mobile device to the PG server if a specific item is selected by the user of the mobile device, and transmitting the second barcode from the PG server to the mobile device.
