Secure Press to Talk (PTT) - Encryption Specifications

Secure Push to Talk Technology

Our Secure Push To Talk (PTT) System allows your field workers, employees or group to keep in constant touch with the office/headquarters and each other. By using their existing mobile phones instead of dedicated walkie-talkie radios, our Secure Push To Talk (PTT) system also allows you to better manage equipment costs as staff need only carry one device.

Push To Talk (PTT) is a secure radio service that uses GSM mobile phones instead of walkie-talkies. It allows instant communication either on a one-to-one basis or as a broadcast to a group of people using Push To Talk (PTT) technology on their mobile phones.

Push To Talk is much quicker than a phone call because there is no number to dial. To make a call, the caller simply pushes a button on the phone and talks. It is similar to a walkie-talkie but has the advantage of almost unlimited (world-wide) coverage as it uses the global GSM mobile phone network.

Push To Talk also integrates seamlessly with your Local Area Network (LAN) and WiFi so that office-based users can keep in contact with field based staff using a PC.

Nabishi Secure PTT Encryption System

Secure Encryption

We use a high security software for our PTT system with up to 5 Layers of protection!

It uses RSA 2048 Master Keys Pair, RSA 1024 Session keys, AES 256-bit, Hardware Random generator and much more to ensure your privacy.

Our Secure PTT system is rated TOP SECRET level of confidence.

RSA Laboratories currently recommends key sizes of 1024 bits for corporate use and 2048 bits for extremely valuable keys like the root key pair used by a certifying authority.
