wireless con 3Com Dynamic Security Link

3Com is addressing the key management and authentication requirements 
through a capability called Dynamic Security Link. When a 3Com wireless 
access point is used in conjunction with 3Com wireless clients, Dynamic 
Security Link automatically generates a brand new 128-bit encryption key 
that is unique to each user and to each networking session.
This kind of security solution provides a much higher level of security 
than static shared-key schemes, and frees users from the hassle of 
manually entering confusing keys.
It also guarantees that each user has a unique key that is constantly 
changed, so even if a hacker does break the encryption and gain access 
to the network, that hacker's key will only work for a few hours, 
limiting potential damage. For additional security, 3Com access points 
can use user authentication whereby all users must log in with a name 
and password at each session.
This user-based authentication capability offers enhanced level of 
security and management compared to device MAC-address based 
authentication schemes.
Another advantage of these access points is that automated and dynamic 
key management capability is implemented right from the access point 
itself, so the solution doesn't require any additional key management 
servers or other infrastructure.

Premesso che il Dynamic Security Link è una soluzione proprietaria 3Com,
qualcuno ha avuto modo di verificare l'efficacia del Dynamic Security Link?

ciao
