PrivateGSM

PrivateGSM is an innovative software to encrypt your calls in a totally safe and legal way through the VoIP Internet Protocol. It needs to be configured on your own PrivateServer or it can auto-configure itself on PrivateWave's hosted server.

Once installed on mobile phones, PrivateGSM gives you the option to encrypt calls between the users (i.e both caller and called need to have the software installed). Using PrivateGSM you can communicate easily and securely with your contacts.

Please keep in mind that there is no way to call numbers on a public switched telephone network (PSTN).

Security:
- Flexible security model:
* ZRTP for end-to-end voice encryption
* SIP/TLS for signaling protection
- Use of only IETF standardized protocols
- Security compliant with FIPS, NIST and NSA
- Based on open source technologies

Performance:
- Low average Bandwith:
* in standby: negligible
* during conversation: (100-200 K/minute)
- International calls and worldwide roaming
- Extremely low battery drain
- Low latency (depends on network)

Supported Networks:
- Any IP-enabled network
- 2G (GPRS, EDGE, 1xRTT)
- 3G (UMTS, HSDPA, EV-DO)
- WiFi
- Satellite

Encryption Algorithms:

- ECDH 256 bit / 384 bit (default) / 521 bit (Elliptic Curve Diffie-Hellman)
- AES256 (CTR) for SRTP
- SIP/TLS with X509v3 digital certificates
