Given its sheer size, protecting the U.S. homeland is a daunting task that requires ongoing multi-agency communication and coordination. From border protection to disaster response to consequence management, defending the homeland requires the development of multiple and changing communities of interest that have a need to share information securely and in real time.
For homeland security coordination, the use of cellular technology is increasing, enabling greater numbers of border agents, check point officers, and other officials with a cell phone to communicate and access time-sensitive, actionable information. Cellular communications over public networks, however, leave the transmitted information – most of which is considered sensitive but unclassified (SBU) – extremely vulnerable to attack.
Cellcrypt allows agencies and individuals charged with protecting the homeland to leverage the ubiquity of cell phones and cellular networks, enabling different levels of government – federal, state, and local – to communicate securely in both planned and “on-the-fly” environments.
The leading provider of encrypted cell phone voice calling, Cellcrypt’s cost-effective, easy-to-use software solutions enable secure communications for the homeland security community wherever and whenever required. Providing an immediate and secure cellular communications link, Cellcrypt’s solutions offer interoperability across multiple and distinct layers of government, plugging existing operational security holes and ensuring mission success. In the critical moments following a disaster, little time is available to set up and manage a secure network, but cellular presents a viable option for first responders and others on the scene. Cellcrypt provides instant security for those conversations, allowing responding agencies and individuals to communicate seamlessly and ensuring privacy of the information being exchanged.

Key Benefits:
Provides for secure information sharing among different and varying communities of interest – both governmental and non-governmental entitiesOperating System
Any IP-enabled network, e.g.
Cellcrypt uses standard encryption technologies including:
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.
