Device for performing quantum-encrypted call and operation method of electronic device

Abstract

In an electronic device and an operation method of the electronic device according to an embodiment, the electronic device may include: a communication circuit, an application processor including at least one processor comprising processing circuitry, and a communication processor including at least one processor comprising processing circuitry, wherein at least one processor, individually and/or collectively, of the application processor is configured to: according to initiation of a call, receive, from a cellular network supporting a quantum encrypted call, identity information of a session of the quantum encrypted call and information indicating a key of the quantum encrypted call, determine a number of times of transmission of at least one packet for identifying whether an external electronic device to be connected via the session has the identity information of the session and/or the key, based on a status of a channel between the electronic device and the cellular network, control the electronic device to transmit the at least one packet to the external electronic device, based on the determined number of times of transmission, and based on the electronic device receiving, from the external electronic device, an acknowledgement packet indicating that the external electronic device has the identity information of the session and the key, perform the quantum encrypted call, based on the key.
