I've developed an IAS plugin, 'MobileKey', that provides 2-Factor Authentication (via SMS) for VPN networks using Microsoft IAS (Win2k/Win2k3) as RADIUS server.
Two authentication modes are supported - Windows password plus SMS access code, and Challenge Password plus SMS access code. Delivering access code by SMS secures the VPN against key-press capture spyware and trojans residing on the client PC.
'MobileKey' is database driven/secured and can comfortably authenticate up to 50,000 users a day with an SMPP connectivity to an SMSC.
I'm now looking for beta testers for this plugin to test out on Cisco and other VPN equipment, as well as partners interested in reselling this kind of solution out of the box, customized or OEM.
'MobileKey' offers unbeatable value for deployments exceeding 30 VPN users as no hardware key is required - your mobilephone is your key generator!
Here's some preliminary information:-
