WEP Open Or Shared, Which One To Use
| ||What kind of wireless security to use - WEP open or shared? Read here the best advice for your wireless network security. |
I will show you what is WEP and how really secure it is. Which one to use, WEP open or shared WEP means Wired Equivalent Privacy. But it has never proven his name. Why is that, you ask? It is really easy to crack it. It does not take more than 2 minutes to crack it with the right tool.
First WEP versions have used the 64-bit shared key. 40 bits are for a shared secret and 24 bits are for IV – initialization vector. IV is used that the receiver could decrypt the frame.
Next improvement of first WEP key was the 128-bit shared WEP key. With that WEP version 104 bits are used for the shared key and 24 for initialization vector. IEEE proposed in 2004 a new version of WEP – WEP2. It uses the same RC4 algorithm with 128-bit initialization vector. WEP2 has not improved significantly security. It only increases the time for cracking.
WEP was designed for minimal data protection in the air. It does not support high level security. There are many of WEP weaknesses:
Here you can find out more about WEP authentication.
1) Manual key management is a big security problem.
2) WEP depends on the secret keys that are widely shared. It could be many users, and the WEP keys must be changed for new users to ensure some level of a security.
3) WEP does not protect users from one another. When all users are using one WEP key, it is easy to decrypt data.
Which authentication to use, open or shared? WEP, as only security method, is not giving you enough security. Open WEP is giving you nothing of the security. With shared WEP you will get the minimum of minimum security. The best solution is to use WPA.
