How Does WiFi Encryption Work?
WiFi encryption is a process that converts plaintext data into unreadable ciphertext, making it difficult for unauthorized parties to intercept and access sensitive information. There are several WiFi encryption protocols, including WEP, WPA, and WPA2, each with its own strengths and weaknesses. The most commonly used protocol is WPA2, which uses the Advanced Encryption Standard (AES) to encrypt data. When a device connects to a WiFi network, it establishes a secure connection with the router, which then encrypts all data transmitted between the device and the network.
The encryption process works by using a shared secret key, known as the pre-shared key (PSK), which is used to encrypt and decrypt data. The PSK is typically a password or phrase that is entered by the user when connecting to the network. Once connected, the device and router use the PSK to generate aunique encryption key, which is used to encrypt all data transmitted over the network. This ensures that even if an unauthorized party intercepts the data, they will not be able to read or access it without the encryption key.
What are the Risks of Using Public WiFi Networks?
Public WiFi networks, such as those found in coffee shops, airports, and hotels, pose significant risks to users who connect to them. These networks are often unsecured or poorly secured, making it easy for hackers to intercept sensitive information, such as passwords, credit card numbers, and personal data.
