Apple has announced a more secure 2048-bit TLS/SSL encryption for iOS push notifications starting December 22, 2010. In an email sent to developers, Apple mentions Push Notifications will now have stronger encryption in the form of 2048-bit TLS/SSL certificates.
Developers are instructed to update their push notifications’ server with a copy of the 2048-bit root certificate from Entrust’s website in order to continue the service beyond December 22, 2010.
