secure jsonp request

[pupx]

Hi

How can I make a secure (or more secure than plain http) json(p) request over http?
I want to make sure that someone who is sniffing the LAN can't get any information about the web service.

Is there a way to encrypt the data on the client side and decrypt it on the server side?

Thank you
Oliver

Unless you use SSL, anything that you are going to be unencrypting can be caught and cracked.
