Today’s law enforcement community requires ongoing and continuous secure communications among differing levels of government, including federal, state, and local, as well as other first responders. The ability to communicate early and often is critical. Interoperability issues surrounding mobile radio systems are well-publicized and have even lead to lives lost. For these reasons, cellular technologies are increasingly being employed by law enforcement personnel for collaboration and coordination. These individuals must trust that the information being shared will not be compromised by “eavesdropping” or other tactics employed by well-funded adversaries, terrorist groups, criminal organizations, or even the media looking to “break a story” by intercepting voice communications.
The leading provider of encrypted cell phone voice calling, Cellcrypt’s cost-effective, easy-to-use software solutions enable secure communications for law enforcement wherever and whenever required. Cellcrypt-secured devices allow for police, federal agents, and others in the field to communicate with confidence, knowing that the information they share is protected.
Cellcrypt’s solutions leverage the ubiquity of the cell phone to provide interoperability across multiple and distinct layers of government, allowing for highly secure communications between law enforcement personnel. The use of secure smart phones obviates the need for expensive, bulky, and conspicuous hardware, allowing law enforcement agents to remain undercover while still offering a highly-secure collaborative environment to assist in carrying out the mission.

Key Benefits:
Operating 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.
