Mobile phone technology is an integral part of every government’s telecommunications infrastructure. Whether in national, regional, or local government departments or part of the national critical infrastructure, mobile phones provide a ubiquitous interoperable tool for real time communications across departments and varying levels of government.
As the mobility requirements for government officials increase, out of convenience or necessity, so too does the requirement to maintain a vital lifeline back to headquarters, as well as the ability to share critical information securely whilst still doing it conveniently, efficiently and effectively. But as the technology has proliferated, so too have the methods and tools of attack, offering foreign operatives/intelligence agencies, terrorists, and other adversaries easy access to a world of information.
Cellcrypt is the leading provider of encrypted mobile phone voice calling through its cost-effective, easy-to-use software solutions that enable secure mobile communications wherever and whenever required. Cellcrypt provides previously unmatched levels of security and flexibility by protecting voice traffic with strong encryption on commercial off-the-shelf smartphones. Cellcrypt leverages the ubiquity of the mobile phone to provide the broadest reach and widest device support, allowing government departments to communicate seamlessly and securely.
In addition, Cellcrypt’s end-to-end security solutions are transport independent and work over all mobile networks, Wi-Fi networks and satellite, making them the most convenient solution for protecting sensitive and confidential telephonic data across government. Cellcrypt secures mobile voice communications across the public network when private networks are unavailable or untenable.
From the battlefield to the boardroom and beyond, Cellcrypt secures mobile voice communications, securing information and protecting conversations from interception and unauthorized disclosure in these key areas: Administrative Departments, Armed Forces, Intelligence Services, National Critical Infrastructure, Public Order, Safety & Law Enforcement, Supply Chain and Partners.
Key BenefitsOperating 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.
