Encrypt connection strings in web config

Hi,
 
We have website hosted on shared server with SQL Server 2005 as database. Now that database server is also shared by other people and hence we have to use SQL Server authentication and we have stored those connection strings in our web.config file.
 
Can we encrypt connection strings? I found few ways to encrypt but in all of them I have to have access to the server and that I don't have.
 
Pls help.
