Zorg is an implementation of the ZRTP protocol. ZRTP is an in-band key exchange protocol for SRTP, based on either the Diffie–Hellman (D–H) or the elliptic curve Diffie–Hellman (ECDH) algorithms, with Man-in-the-Middle protection based on human voice recognition.
...
Zorg implementations are developed in cross-platform C++ language and Java language in order to run on most mobile phones and all desktop platforms.
Key Zorg features are:
- 100% open source
- ZRTP standard compliance
- Supported platforms:Blackberry, Android, iPhone, Symbian,Windows, Linux, MacOS X
- Language bindings for: C++, C/Objective-C, Java, J2ME MIDP 2.0
- Modular design, especially w.r.t. cryptography suites
- Especially optimized for mobile platforms
- Used in production in commercial grade security software
- Support ZRTP masquerading to bypass restrictive PBX that block ZRTP packets
- Made in EU - not restricted by US Export Control (but Internationally by Wassenaar Arrangement)
...
The project is sponsored by PrivateWave, an European (Italy) company that uses ZRTP security in its PrivateGSM voice encryption product for Blackberry, Nokia and iPhone following anan open source and transparent security approach.
