You can keep some specific HTTP headers in the request. The desktop application must send those headers to your application or else your website should return "unauthorized access" kind of message. These headers could be like UserName and Password.

I passed username with encrypted format but is link secure or not.. In my office there are workers who access this link if any one copy this link and use from at own home then ?

If the username and the password in HTTP header (not query string) does not match, then they should not be allowed further. Your website should check for that as soon as a page is requested.

One way to do this is to pass a secure token or key which is shared across the client or server.
The algorithm that generates the key is shared across both so that the server understands the key sent by the client.

This could help you get started - Client/Server Encryption plus extras[^].

Another way to do this could be to use an SSL certification that would be installed on the client - however, that is probably not the best approach for a Silverlight application running in a sandbox.

If you're using a regular URL browser query, why not add ?ref=[app] to the querystring...
