About Cellcrypt Federal
For Government and Approved Use Only – Can only be used with an Approved License.
NIAP and FIPS-certified, Cellcrypt Federal enables security for communications in approved government networks, with End-to-End Encryption that exceeds the standards for US Top Secret and incorporates Post-Quantum Cryptography.
Secure Instant Messaging
Cellcrypt Federal 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. Cellcrypt Federal’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 on their device.
Secure Voice and Video Calls
Cellcrypt Federal’s 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 and to prevent Man-in-the-Middle (MitM) attacks.
Secure Conference Calls
A conference bridge can be established instantly by creating a group of contacts and hitting the call button. With only mutually authenticated, authorized users, Cellcrypt Federal conference calls eliminate the need for participant PINs and passwords.
Work Anywhere, on Any Device
Cellcrypt Federal can be downloaded instantly for immediate use with no additional hardware dependencies.
End-to-End Encryption
Cellcrypt Federal 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 certified. With Cellcrypt Federal, 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.
