Which of the following is known to be the WEAKEST encryption standard?

WPA (Wi-Fi Protected Access) is a stronger standard than WEP, introducing improvements like TKIP and often used with PSK or 802.1X for better security.

WEP (Wired Equivalent Privacy) is an older wireless security protocol that uses a static pre-shared key and has significant known cryptographic vulnerabilities, making it easily crackable with readily available tools. Its weaknesses stem from issues like short initialization vectors (IVs) and predictable key streams, which allow for successful attacks to recover the WEP key.

AES (Advanced Encryption Standard) is a strong symmetric encryption algorithm widely used in modern security protocols like WPA2 and WPA3 for robust data protection.

TKIP (Temporal Key Integrity Protocol) was an enhancement to WPA1 to address WEP's flaws but has its own vulnerabilities and is less secure than AES, though stronger than WEP.
