For the protection of voice calls, instant messages and content, the Encrypted Mobile Content Protocol™ (EMCP) optimizes the delivery of encrypted content in real-time, even across low-bandwidth wireless networks.

 

Cellcrypt uses standard encryption technologies including:

  • Advanced Encryption Standard (AES) for symmetric encryption

  • 384-bit Elliptic Curve Cryptography for Authentication

  • Elliptic Curve Diffie-Hellman (ECDH) for key agreement

  • Secure Hash Algorithm (SHA) for message digest

 

Cellcrypt’s Dual Cipher system uses double-wrapping for added security. For example, voice calls are first encrypted using RC4 with a 384-bit key and then encrypted again using AES with a 256-bit key.

Cryptography
Key Generation

 

  • Entropy collected continuously from hardware sources e.g. motion sensor, mic, and OS sources e.g. /dev/urandom

  • Long term ECC keys generated & stored in application’s secure database

  • No manufactured/generated key material is needed before the use of the system

Voice Call Authentication

 

  • Secure data exchange in two stages

  • End-to-end standards-based key establishment providing mutual authentication, Perfect Forward Secrecy (PFS) and unique keys per-session

    • NIST SP800-56A C(2,2) Full Unified Model with
      Bi-lateral Key Confirmation

    • Authentication using NIST approved ECC curve P-384

Message Authentication

 

  • An end-to-end, standards-based, key establishment with mutual authentication

    • NIST SP800-56A C(1,2) One-Pass Unified Model

    • Public key fingerprint displayed in message dialog and contact details for vocal confirmation

Symmetric Cryptography

 

  • Dual ciphers - RC4 with 384-bit key and AES-CTR with 256-bit key

    • FIPS SP 800-38 – AES in CTR mode and AES in GCM mode (rev D)

NIST FIPS 140-2 Level 1 Certified
Cellcrypt is certified to the FIPS 140-2 standard, approved by the US National Institute of Standards & Technology (NIST).
