Military-Grade Encryption 
for Secure Communication

Seecrypt provides secure voice calls, messages and file transfers between trusted mobile devices via high grade, multi-layered encryption

Protection of all communication and content is guaranteed by the Encrypted Mobile Content Protocol™ (EMCP), with real-time optimized delivery of encrypted content, even across low-bandwidth wireless networks.


Seecrypt 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


Seecrypt’s Dual Cipher system uses double-wrapping for added security. Voice calls, for example, are first encrypted using RC4 with a 384-bit key, followed by a second encryption operation, again using AES with a 256-bit key.


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 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
  • 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)
