It is used in popular … WebMar 12, 2024 · Recent research shows that WEP is not secure as it does not use RC4 and CRC-32 correctly. The latest IEEE 802.11i draft uses a new keyed hash function, called Michael, as the message integrity code. To address the WEP vulnerabilities, the IEEE 802.11 Task Group i (TGi) provides a short-term solution and a long-term solution.
