MTN NAMCHAT Description
MTN NAMCHAT enables security for communications that exceeds the standards for US Top Secret and incorporates Post-Quantum Protection.

Secure Instant Messaging
MTN NAMCHAT provides secure instant messaging with the ability to send photos, videos, voice notes, and large files of any kind. All messages and files are end-to-end encrypted with a new key generated for every message or file sent. MTN NAMCHAT’s enhanced Data at Rest encryption protects all files and media stored within the app.​

Group messaging for collaboration and file-sharing can be created locally by the user on their device.

Secure Voice and Video Calls
MTN NAMCHAT voice and video calls are fully encrypted end-to-end, and routed through the mobile device’s data connection with signal obfuscation. Advanced codecs ensure HD quality with minimal data and battery use, even across low-bandwidth mobile or wireless networks.

Secure calls can be made over any IP-based network, including 5G, 4G/LTE, 3G/HSDPA, 2G/EDGE, WiFi, and satellite networks, with full authentication of all parties on a call to eliminate the risks of impersonation through Caller ID spoofing.

Secure Conference Calls
A conference bridge can be established instantly from the MTN NAMCHAT app by creating a group of contacts and hitting the call button. With only mutually authenticated, authorised users, MTN NAMCHAT conference calls eliminate the need for participant PINs and passwords.

End-to-End Encryption
MTN NAMCHAT uses double-layer encryption in an end-to-end configuration, with a new key for every call and message. The system is modular and adheres to best practice cryptographic standards/protocols, powered by a crypto core that is FIPS 140-2 validated. With MTN NAMCHAT, data is secured end-to-end using Elliptic Curve and Symmetric-Key Cryptography.

For post-quantum protection, the underlying cryptography is overlaid with Supersingular Isogeny Diffie-Hellman Key Exchange (SIDH 751) for voice and video, and Supersingular Isogeny Key Encapsulation (SIKE 751) for messaging and files.
