Cellcrypts Technology
Cellcrypt's advanced solution leads the industry in delivering multi-layered security to establish a
high-performance encrypted voice call between trusted wireless devices. It utilises Encrypted Mobile
Content Protocol (EMCP), a set of standards-based protocols for optimising delivery of encrypted
real-time content between mobile phones over low-bandwidth wireless networks. Cellcrypt's products are
certified to the FIPS 140-2 standard, approved by the US National Institute of Standards & Technology
(NIST).
Cryptography & Random Number Generation
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 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) Contact Cellcrypt:
Both encryption algorithms are used at the same time. The data packet is first encrypted with RC4 and Europe
the cipher text is then encrypted again with AES in Counter Mode (CTR). Both algorithms are initialised 13-15 Carteret Street
