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:
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.
I am not using usernames/passwords, and the server has REST interfaces defined to read/post data.
any ideas? appreciate any/all help.

I would suggest challenge/response certification of your application. embed a key in the app, the server sends a message, you post your data and a computation is done to the challenge data and return that also.
