Explanation

The best way to protect the confidentiality of data transmitted in a wireless LAN is to encrypt it using dynamic keys. Dynamic encryption keys change regularly, making it more difficult for attackers to intercept or decrypt the data. This approach provides stronger security compared to static keys, as static keys are more vulnerable to attacks over time.
