Abstract
Given the rise in popularity of communicating personal, private, sensitive, or vital peer-to-peer or peer-to-group information over insecure text messaging infrastructure, it would be highly desirable to provide a lightweight solution that enables the exchange of information in a secure manner. The non-limiting technology herein provides systems and methods for the exchange of cryptographic material that can be used to encipher message-oriented communications between at least two peer devices. Once the cryptographic material is exchanged between cooperating peers, this lightweight solution can be used by common off the shelf hardware such as smartphones, tablets, feature phones, or special purpose machine to machine devices for private communications, such as command and control, location services, etc. using insecure voice or data communication paths, such as SMS.
