Abstract
An electronic device may include at least one wireless communication module configured to transmit and receive a wireless signal; a memory electrically configured to store instructions; and at least one processor operatively connected to the at least one wireless communication module and the memory, the at least one processor being configured to execute the instructions to: based on an attempt to connect to an access point (AP), identify whether a pairwise master key security association (PMKSA) for the AP, generated based on to a previous connection of the electronic device to the AP, is present, and based on identifying that the PMKSA is present, determine whether to reuse a pairwise master key (PMK) stored in the PMKSA by comparing a lifetime of the PMK with a margin time in which a use of the PMK is guaranteed.
