While RC4 was still a bad choice, TKIP meant that many people could achieve a very basic level of security with just a firmware upgrade.ĪES is a well-known, secure block cipher for encrypting data, and CCMP is a mode of using this cipher to provide both strong encryption and robust integrity protection.

It used a new, per-packet key for each packet plus a (weak) integrity check. WPA was designed to fix this problem without requiring new hardware by implementing TKIP, the Temporal Key Integrity Protocol.
Combined with the fact that RC4 has known statistical weaknesses and there was no integrity check to prevent tampering, this design meant that WEP was exceedingly weak and using it was little better than sending data unencrypted. RC4, however, is vulnerable to related-key attacks, which means using similar keys causes security problems, and 24 bits is not sufficient for a nonce size, which means that the same nonce (and hence the same keystream) was reused. However, when dealing with packets, it's not possible to guarantee all data arrives in the same order without packet loss, WEP specified a 24-bit nonce as part of the key. Because RC4 does not accept a nonce, it produces a single stream of output. The original WEP used the stream cipher RC4 with a 104-bit key. Each of them specifies different behavior and offers different options. WEP, WPA, WPA2, and WPA3 refer to different certifications for securing a wireless network, each requiring certain standards.
