Abstract
A system for establishing a registration for secure communication between a mobile device and a server includes a server configured to: determine the phone number of the mobile device from which the SMS or MMS message is originated; and verify the phone number of the mobile device originating the SMS or MMS message against a whitelist to authorize a registration between the mobile device and the server. The server can establish an encryption key between the mobile device and the server, which can used to provide or enhance encryption of a voice communication, such as a VoIP communication, made using the mobile device. The server can renew the encryption key based on one or more policies determined by an administrator. The server can be configured to verify a secure identification code that is input at the mobile device and which can be provided to a user of the mobile device before the mobile device is registered with the server.
