Provided is an electronic device including a communication module configured to exchange data with an external device, in which the communication module includes a first core and a second core, a memory storing instructions, and a processor configured to execute the instructions to determine first channels to be scanned by the first core and second channels to be scanned by the second core, scan the first channels by using the first core, scan the second channels by using the second core, determine third channels to be scanned by the first core and fourth channels to be scanned by the second core, based on a non-PSC detected based on at least one of the first channels and the second channels, scan the third channels by using the first core, and scan the fourth channels by using the second core.

Method and electronic device for scanning channels in frequency bands

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.

Electronic device and method of using pairwise master key

An electronic device according to various embodiments may include: a communication circuit, a memory, and at least one processor functionally connected to the communication circuit and the memory, wherein the at least one processor is configured to: perform wireless communication with an external electronic device through the communication circuit, based on a shared secret key generated by the electronic device in a process of configuring an association with the external electronic device, transmit, to the external electronic device through the communication circuit, a renewal frame for renewing the shared secret key, at a time point at which a lifetime of the shared secret key expires or at a time point a specified time ahead of the time point at which the lifetime of the shared secret key expires, and renew the shared secret key to perform wireless communication with the external electronic device through the communication circuit, based on the renewed shared secret key.
