Abstract: Provided is a method of distributing an application including transmitting, by a distribution server, a signal for requesting metadata to a user terminal where an application is installed; receiving, by the distribution server, a reply including first metadata from the user terminal; determining, by the distribution server, whether the first metadata is valid based on second metadata corresponding to the application; setting a connection with the user terminal to re-install the application on the user terminal if the distribution server determines that the first metadata is not valid; encrypting, by the distribution server, one or more installation files that install the application with a private key; and transmitting the one or more encrypted installation files via the set connection to the user terminal.
