restful-authentication

Hello everyone, i am trying to write a restful google app engine application (python) that accepts requests only from another GAE that i wrote. I dont like any of the ways that i thought of to get this done, please advice if you know of something better than:

Get SSL setup, and simply add the credentials on the request that my consuming app will send. I dont like it cause SSL will slow things down.
Security by obsecurity. Pass a long number by my consuming app that is in Xmod0, where X is a secret number that both applications know. I just,,,, dont like this.
Check the HTTP header to see where is the request coming from. This option is the one that i hate the least, not alot of processing, and spoofing an HTTP request is not really worth it, for my application's data.

Is there any other clean solution for this?
