Cellcrypt Solutions for Intelligence Services

Communicating in Covert, Undercover Environments

Cellcrypt Solutions for Communicating in Covert, Undercover EnvironmentsIntelligence agencies deploy personnel around the world, often in volatile or even openly hostile environments. To remain connected and inconspicuous, field officers rely on widely available mobile networks and everyday smart phones for communication and coordination across the public network when private networks are unavailable or untenable. For these field officers, security and cover are top concerns.

The leading provider of encrypted mobile phone voice calling, Cellcrypt’s cost-effective, easy-to-use software solutions enable secure communications for members of the intelligence community wherever and whenever required. Cellcrypt’s solutions provide unmatched levels of security by protecting sensitive voice communications, ensuring the privacy of communications among multiple communities of interest without the need for expensive, bulky, and conspicuous hardware. In addition, Cellcrypt’s internal key management feature allows for faster deployment throughout the field and a less vulnerable solution due to no external key management interfaces.

Operating System

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

Any IP-enabled network, e.g.

  • GSM/CDMA
  • 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.
