Abstract
A solution that enables the exchange of information in a secure manner over an insecure text messaging infrastructure provides part of the exchange as cryptographic material to be used to secure subsequent communications. The exchange of the cryptographic material is protected from malicious and nefarious parties. Systems and methods for the exchange of cryptographic material enable the parties involved in the exchange to have confidence that the material received was communicated from the originating party. Once the cryptographic material is successfully exchanged between cooperating peers, it can be used by smartphones, tablets, feature phones, or special purpose machine to machine devices for private communications, such as command and control, location services, etc. over insecure voice or data communication paths, such as SMS.
