Why are WEP and RC4 bad for security?
In: 3
Encryption involves using math to make something hard to figure out, but if you know the right math, you can essentially prove to the encryption that you are allowed to see what it’s guarding. This is important for later.
The encryption of WEP is weak. it used to be good in the 90s when it was new, however vulnerabilities have since been found, as well as the fact that computer power has increased, meaning modern computers can exhaust all of the options of math within a reasonable amount of time to find what the encryption is looking for.
Think of a door lock. WEP is like a lock with 2 cheap pins. You can either put in the key and turn it, or you can hit the lock kinda hard while turning the handle and it’ll pop open.
More modern encryption options use longer keys, “more pins in the lock” if you will, as well as just better made locks aka better designed encryption algorithms that are harder to break open.
