Systems and methods for encrypted mobile voice communications

摘要

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.

主权项

1. A system for establishing a registration for secure communication between a server and an application on a mobile device, the system comprising:
a software module configured to run as an application on a mobile device, wherein the mobile device has an associated phone number and the software module is configured to encrypt an SMS message or an MMS message via an encryption; wherein the application is configured to create registration information including at least one of a secure identification code and an encryption key for encrypted communication between a server and the application; wherein the mobile device, is configured to send to the server a first short messaging service (SMS) message or multimedia messaging service (MMS) message originated by the mobile device and to thereby reveal the phone number to the server; wherein the server is configured to 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; wherein the mobile device is configured to, if the registration is authorized, receive a code sent by the server to the application on the mobile device via a second SMS message or MMS message; and wherein the mobile device is configured to, without user intervention, extract the code from the second SMS or MMS message and send at least one of the registration information and the code to the server.
