MTN NAMCHAT enables security for communications that exceed the standards for Top Secret and incorporates Post-Quantum Protection. Secure Instant MessagingMTN 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.Groups for messaging and file-sharing can be created instantly by the user.Secure Voice and Video CallsMTN NAMCHAT voice and video calls are fully encrypted end-to-end, 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 CallsA conference bridge can be established instantly from the MTN NAMCHAT app by creating a group of contacts and hitting the call button.

The system is modular and adheres to best practice cryptographic standards/protocols. 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.
