System and method for installing smart card applet

Abstract

Disclosed are a system and a method for installing a smart card applet. A response message for an OTA message received from an external remote server is transmitted to form a communication channel based on HTTP (hyper text transfer protocol) between a smart card and the remote server. The applet is installed based on applet installation information received through the communication channel. A large scale applet is installed in a card within a short period of time.

1 . A method for installing a smart card applet, the method comprising:
 establishing, by a SCWS, a communication channel based on HTTP by transmitting a message in response to an OTA message received from a remote server;   calling, by the SCWS, a RAM servlet when an applet installation request message is received from the remote server;   identifying, by the RAM servlet, the remote server based on identity information included in the applet installation request message;   transmitting, by the SCWS, an applet installation code to the RAM servlet when the applet installation code is received from the remote server after identification of the remote server has been completed; and   installing, by a RAM, the applet when the applet installation code is received from the RAM servlet.   
     
     
         2 . The method of  claim 1 , wherein the SCWS receives the OTA message in the form of a short message from the remote server. 
     
     
         3 . The method of  claim 1 , wherein the calling calls the RAM servlet, which is mapped to an URL, based on the URL included in the applet installation request message. 
     
     
         4 . The method of  claim 1 , wherein the transmitting comprises:
 dividing the applet installation code based on the size of the applet installation code; and transmitting the divided applet installation code to the RAM servlet.   
     
     
         5 . A computer-readable recording medium comprising computer readable code to control at least one processing device to implement a method for installing a smart card applet, the method comprising:
 establishing, by a SCWS, a communication channel based on HTTP by transmitting a message in response to an OTA message received from a remote server;   calling, by the SCWS, a RAM servlet when an applet installation request message is received from the remote server;   identifying, by the RAM servlet, the remote server based on identity information included in the applet installation request message;   transmitting, by the SCWS, an applet installation code to the RAM servlet when the applet installation code is received from the remote server after identification of the remote server has been completed; and   installing, by a RAM, the applet when the applet installation code is received from the RAM servlet.
