Dozix007 writes "IEEE has approved a
new wireless security protocol dubbed 802.11i, intended to finally
provide sufficient security for wireless connections that users don't
need to rely on alternate security layers. The new specification works
by using AES encryption
in the transceiver itself, encrypting data directly at the level just
above the actual radio pulses themselves. That makes it transparent for
applications sending data through the radio, so legacy programs running
on new 802.11i-compliant hardware will automatically get the benefits
of the new protocol without the need for modification."
Computers are unreliable, but humans are even more unreliable.
Any system which depends on human reliability is unreliable.
