Cellcrypt Solutions for the Department of Defense

Secure, Agile Information Sharing to the Edge

Cellcrypt’s highly-scalable and quickly-deployable voice encryption solutions With troops deployed around the world, today’s military requires agile information sharing capabilities in support of time-sensitive, mission- critical operations to the edge. Internal and external coordination and real-time communication among all military branches as well as Coalition and allied forces is critical. Often rugged mountainous terrain or other hostile environments limit communications options. Due to unavailable or untenable private networks in these environments, generally the only mechanism for operational or personal communications is across a public cellular network.

Cellular communications over these public networks leave the transmitted information – most of which is considered sensitive but unclassified (SBU) – extremely vulnerable to attack. The leading provider of encrypted cell phone voice calling, Cellcrypt’s cost-effective, easy- to-use software solutions enable secure communications wherever and whenever required. Around the beltway or around the world, Cellcrypt’s highly-scalable and quickly-deployable solutions leverage commercial-off- the-shelf cell phones to provide unmatched levels of security by protecting all SBU information.

Cellcrypt solutions also support the Department of Defense’s (DoD) ongoing need to coordinate and communicate with its inter-agency partners in civilian government, including homeland security and emergency response organizations. Whether conducting day-to-day business or coordinating disaster response, Cellcrypt allows DoD to leverage the ubiquity of the cell phone, enabling seamless and secure interoperability across agencies and among unique and changing communities of interest, all in a protected environment.

Operating System

  • AndroidTM
  • BlackBerry®
  • iOS
  • Symbian S60 (Nokia E-Series, N-Series devices)
     

Any IP-enabled network, e.g.

  • 2G
  • 3G
  • 4G
  • Satellite
  • Wi-Fi™

Cellcrypt uses standard encryption technologies including:

  • Advanced Encryption Standard (AES) for symmetric encryption
  • Elliptic-Curve Digital Signature Algorithm (ECDSA) for digital signatures
  • Elliptic Curve Diffie-Hellman (ECDH) for key agreement
  • Secure Hash Algorithm (SHA) for message digest

In addition, before these algorithms are processed, Cellcrypt uses additional algorithms for added security (double-wrapping). For example, the voice call is first encrypted using RC4-256 bit and then encrypted again using AES-256 bit.

Public Cryptography
(2048-bit RSA, & ECDSA, ECDH using curves with 384-bit prime moduli)
RSA and ECDSA are used for authentication. The key pairs are generated on the phone during the installation and are unique to each phone. A private key is never shared. The Elliptic Curve Diffie-Hellman (ECDH) and RSA algorithms are used for key exchange. The session key is only valid for one phone call and securely destroyed after use.

Symmetric Cryptography
(AES & RC4, both 256 bits)
Both encryption algorithms are used at the same time. The data packet is first encrypted with RC4 and the cipher text is then encrypted again with AES in Counter Mode (CTR). Both algorithms are initialized with the exchanged session keys.

Hashing Algorithms
(SHA512)
Industry standard hashing algorithms are used for increased integrity assurance.

Random Number Generation
A 2048 bit seed pool is generated during the installation and is periodically updated. The initial seed is derived from the microphone input.
