The secure element further stores a list with which a part or all of identification information of the at least one application package is registered. The processor controls the secure element such that an application package indicated by the identification information registered with the list is uninstalled, in response to a specified event. Various other embodiments recognized from the specification are also possible.

Secure element management and electronic device performing same and installation package

An electronic device and a program management method therefor are provided. The electronic device includes a communication interface, a memory, at least one processor, and a secure circuitry. The secure circuitry is configured to provide a first public key stored in the secure circuitry to the at least one processor. The at least one processor is configured to transmit the first public key to an external device and receive an encrypted secure program encrypted based on the first public key and a second public key generated by the external device, from the external device. The at least one processor is further configured to transmit the second public key and the encrypted secure program to the secure circuitry. The secure circuitry is configured to decrypt the encrypted secure program based on the second public key and a first private key which is symmetrical to the first public key.

Method and apparatus for managing program of electronic device

A method of a first electronic device to display a preview image is provided. The method includes receiving, by the first electronic device, a user input for setting a screen of a second electronic device, transmitting, by the first electronic device, setting information based on the user input to the second electronic device, receiving, by the first electronic device, the preview image from the second electronic device, and displaying, by the first electronic device, the received preview image, wherein the preview image is for the screen of the second electronic device.
