ELECTRONIC DEVICE AND METHOD OF USING PAIRWISE MASTER KEY - A simplified explanation of the abstract
This abstract first appeared for US patent application 17863085 titled 'ELECTRONIC DEVICE AND METHOD OF USING PAIRWISE MASTER KEY
Simplified Explanation
The abstract describes an electronic device that can connect to a wireless access point (AP) using a pairwise master key security association (PMKSA). The device checks if a PMKSA for the AP exists and determines whether to reuse a stored pairwise master key (PMK) based on its lifetime and a margin time.
- The electronic device has a wireless communication module, memory, and processor.
- It can connect to an AP using a PMKSA generated from a previous connection.
- The device checks if the PMKSA exists when attempting to connect to the AP.
- If the PMKSA is present, it compares the lifetime of the stored PMK with a margin time.
- Based on this comparison, the device decides whether to reuse the PMK.
Potential Applications
- This technology can be applied in various electronic devices that connect to wireless networks, such as smartphones, laptops, and IoT devices.
- It can enhance the security and efficiency of wireless connections by reusing PMKs when appropriate.
Problems Solved
- The technology solves the problem of inefficiently generating new PMKs for every connection attempt to an AP.
- It addresses the issue of potentially using outdated PMKs by comparing their lifetime with a margin time.
Benefits
- By reusing PMKs, the electronic device can establish connections more quickly and efficiently.
- The technology improves the overall performance and reliability of wireless connections.
- It ensures that PMKs are used within a guaranteed time frame, enhancing security and preventing the use of outdated keys.
Original Abstract Submitted
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.
