authentication

Hi,

"share key" auth and "open auth", which one is stronger?

open auth is for public access

share key for small group access

Both of them are not secure but which one is bad?

Re: authentication

Shared Key Authentication is not considered secure, because a hacker who detects both the clear-text challenge and the same challenge encrypted with a WEP key can decipher the WEP key. With Open Key Authentication, even if a client can complete authentication and associate with an AP, the use of WEP prevents the client from sending data to and receiving data from the AP, unless the client has the correct WEP key.
