secure iPhone to server communication so that only my app can post data?
<p>I am working on an iPhone app that has to post some data to a server e.g. say user's votes for on a topic. Here's the problem:</p>

<p>I want to implement some form of encryption so that only my iPhone clients can post votes to the server, no other devices/sources may post data.</p>

<p>I am not using usernames/passwords, and the server has REST interfaces defined to read/post data.</p>

<p>any ideas? appreciate any/all help.</p>
