We are facing problem with PPPoE in ethernet access

To provide high speed access, 10Mbps/100Mbps ethernet
is used as access method. But, we found some guy
'steal' some other's account by listening to
broadcasting packets, and they also set up 'phishing'
PPPoE server to catch those PPPoE authentication

With ATM DSLAM,we could solve this by binding account
with PVC. With ethernet, although we could seperate
subscribers into VLANs there is more than 100
subscribers within one VLAN. 

What's your method to deal with such problem? Will
CHAP in PPPoE help?
