Enhanced encryption protocols
- [Instructor] We said that WEP gave us very limited security because of the way it implemented the RC4 encryption algorithm. So let's consider some enhancements that can give us better security. After WEP was discovered to be quite vulnerable to attack, TKIP was introduced for wireless security. And TKIP stands for Temporal Key Integrity Protocol, and it dramatically improved on the encryption provided by WEP. It does still use that RC4 algorithm as the underlying encryption algorithm, but it changed how that initialization vector was combined with the key, and it also used a longer initialization vector. It uses a 48-bit initialization vector, as opposed to WEP's 24-bit initialization vector. And that's going to make it mathematically much more difficult to derive the shared secret key. And going a step beyond TKIP, we have AES, which stands for Advanced Encryption Standard. And that is significantly stronger than TKIP…
