InterLink’s LucidLink Wireless Security software fortifies the Wi-Fi networks of small businesses with encrypted security that can be remotely managed to allow or deny user access to the network through a simple interface, said Mike Klein, president and CEO of InterLink, Ann Arbor, Mich.

In just a few steps, a small business can set up a list of authorized wireless network users with LucidLink. Full wireless access can be granted to certain employees, while policies such as session expiration times can be applied to others, Klein said.

“It’s just as nontechnical as you can get,” he said. “But it uses high-end security technology.”

LucidLink Wireless Security software works using encryption keys bound to the client device, credentials that cannot be compromised even if a user’s wireless laptop is stolen, Klein said. The 128-bit encrypted credentials are created using the Diffie-Hellman key agreement protocol, which allows two users to exchange a secret key over an insecure medium. Man-in-the-middle attempts at stealing a key are prevented by using out-of-band security code information, he said.

Matthew Ellsworth, systems and sales engineer at ABC-US, a VAR in Norcross, Ga., said when he shows the LucidLink system to customers, he tells them, “a password is a password. It’s hackable. But LucidLink doesn’t use passwords. It’s secure.”

LucidLink supports wireless access points from 3Com, Cisco Systems, D-Link, Linksys, Netgear, Motorola, Proxim, SMC, Symbol, ZyXel and others. Pricing begins at $449 for a 10-user license.
