Possible to secure WEP?

I am using a WEP wireless modem that does not have the ability to do
WPA.

I have my file sharing turned off on the wireless computer (laptop)
and use it in my home only. I have no interest in connecting computers
together to share files, it's strictly a wireless internet
connectivity setup.

Is there any way to secure the data that passes over the wireless so
that it is not available to hackers without buying a different router?
I want the data that I send over the air to be relatively secure and I
want to make sure no one accesses my system via the wireless.

Thanks,

A

You could change the key every 5 minutes?

Actually, it is possible to secure a wireless network against both
intrusion and sniffing without any encryption of any type. It's
called a VPN (virtual private network). The random user connects to
the network and is give a totally useless IP address by the DHCP
server. The default gateway goes only to the VPN server. Without the
complex authorization and authentication keys needed to connect to the
VPN, the random user gets nowhere. However, if they successfully
authenticate with the VPN, a new additional IP address gets issued,
with a gateway that points to the corporate LAN or to the internet. At
this point, it looks just like a normal wireless connection, except
that everything is encapsulated and encrypted inside the VPN packets.

The catch is that your home network will need some type of local
server that can terminate the VPN. As such, it's not really a
suitable solution for home networks but might give you some ideas. If
I were to propose such a system, I would need a router that can
terminate the VPN, such as a Sonicwall, Netgeear or Netscreen VPN
router. The wireless could be provided by a simple wireless access
point (or wireless router with the router section disabled) or by a
VPN router that has built in wireless. I'm too lazy to itemize
models. That will work, but with the added hardware and complexity,
you may as well just buy a router that does WPA and forget the VPN.

I was thinking more along the lines proxy software on both ends of the
wireless, where the user could define the method of encryption or set
up a table to change the key every so often automatically, most
machines with internet access can easily maintain time within a few
seconds, so the keys could be changed on a predefined schedule. This
would be software running in the PC, so perhaps this is a weakness.

You could do that, want to buy a client that does that? email me

Oh and of course you have changed the parameters, your original question
was whether it was possible to secure WEP and now it's not in the
picture.

Incidentally, the client software that I have in mind would require two
licences to be legal and the cost would exceed that of a home router
that did WPA.

Setup VPN :-)

Bzzzt, cheating, that's not using WEP and requires an endpoint

You guys are just reinventing WPA - TKIP

Nope, what I have will do AES256 client to client, can do wired/wireless
or both, already exists, nothing to be (re)invented

AP can be left completely open.
