Summary

Wireless encryption is a method used to secure data transmitted over wireless networks, like Wi-Fi. It protects information from unauthorised access and ensures privacy. 

Encryption scrambles data into a secret code during transmission and is decrypted back to its original form when received by the authorised user. This process uses a secret key, known only to the sender and receiver, to encrypt and decrypt the data, making it difficult for hackers to read or misuse the information.
