Why can we crack WEP ?

I got WEP key from any access point! But, I'm very curiously! I have a question "Why can we crack WEP by capturing a large number of IVs?"
Please, explain for me !

simple answer, because of the weaknesses in the algorithm.

If you want more, then please rephrase your question to give us as much info as possible. From what you have put it is impossible to see what you are actually asking for.

Uhm, thanks to your reply !

The purpose of my question is "What are the weaknesses in the algorithm?", I read some document. I know IVs has weaknesses, but I cann't understand why IVs has weakness. These documents only write "weakness in IVs", but don't write the reason. I want to know the reason, please explain for me ! :)

Google, Google, Google, and then more Google. Seriously. It's all out there.

Because someone fscked up in writing the code, that's why.

In lay mans terms. Every time a iv is set out it contains a small piece of the key used for verification. If you capture enough ivs they go together in a mathamatical algorithim unique to each mac address. The program aircrack can DO THE MATH.:D

Do you have algorithm create IVs, CRC of WEP ?

Why would WE have it ? How would WE get it ? think about it for more than a nano second.

If we had the algorithm then we would only need to receive a couple of packets to be able to reverse the key. Instead we need thousands to brute force the key.

Once again, people fail to follow simple guidelines...
