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.

Systems and methods for encrypted mobile voice communications

A method of establishing a registration between a mobile device and a server includes receiving at the server an SMS or MMS from a mobile device. The server receives the phone number of the mobile device, verifies the phone number of the mobile device against a whitelist to authorize a registration between the mobile device and the server, and verifies a secure identification code that is input at the mobile device. The secure identification code is provided to a user of the mobile phone before the mobile device is registered with the server. The secure identification code can be provided to the user via an administrator of the server. An encryption key established between the mobile device and the server can be used to provide or enhance encryption of a voice communication, such as a VoIP communication, made using the mobile device.
