Detailed explanation-1: -WEP (Wired Equivalent Privacy) is the oldest and most common Wi-Fi security protocol. It was the privacy component established in the IEEE 802.11, a set of technical standards that aimed to provide a wireless local area network (WLAN) with a comparable level of security to a wired local area network (LAN).
Detailed explanation-2: -A WEP-protected network can be cracked in under a minute, especially if the network sees a lot of traffic. Threat actors are then able to intercept a large number of data packets. WEP has been demonstrated to be extremely insecure and should not be used to protect Wi-Fi networks.
Detailed explanation-3: -WEP uses the RC4 (Rivest Cipher 4) stream cipher for authentication and encryption. The standard originally specified a 40-bit, preshared encryption key. A 104-bit key later became available after the U.S. government lifted certain federal restrictions.
Detailed explanation-4: -NFC is based on wireless technology while RFID is not. RFID is faster than NFC. RFID is designed for paper-based tags while NFC is not. NFC devices cannot pair as quickly as RFID devices.
