Secure Media Communication


Communication security has gained importance, because of the increased role of mobile devices in our everyday lives and the ongoing investments in the internet infrastructure. Open internet networks (such as those at airports, shopping malls, etc.) are vulnerable to malicious attacks.

As the usage of the smartphones increased with the help of the high cellular network speeds, the usage of voice-over-ip communication is dramatically increased. The security of the content of the communication becomes crucial in some areas such as Military, Government Agencies, Private Companies, etc.

Regarding all these, the importance of the multimedia communication over IP networks becomes more important.

Nova MPS provides security for both inter-client communication and client-server communication, even in non-secure open networks regardless of device and operating system.

Nova MSP client application benefits from state-of-the-art technologies and offers secure voice and video communication and instant messaging platform that prevents man-in-the-middle, intervention, eavesdropping attack. The MPS Signaling Server, developed internally is able to perform all signaling operations including initiating calls and sending messages.

Communication between the two clients is encrypted using encryption and key exchange algorithms such as AES256, Blowfish, TribleDES, Diffie-Hellman, and all content can only be viewed by clients. The NOVA MSP system offers software-based data, voice and video encryption options with smart cards and hardware based or no card, according to customer needs. There are also legal listening and no listening modes in accordance with customer needs. We recommend our Nova MSP product to all telecommunication companies, service providers and all public institutions and organizations that need secure end-to-end communication. With secure vehicle tracking system and safe whiteboard application features , logistics, training and many other sectors will be provided a safe environment.





  • Signaling Server is responsible for all signalizations such as Login, Im, and Call. Developed with java framework, so that it is operation system independent.
  • Smartcard Initialization Application prepares a new smartcard ready for use.
  • Turn Server (Traversal Using Relay NAT) assists in traversal of network address translators (NAT) or firewalls for multimedia applications.
  • Admin Web Application is a server monitoring application shows us about Server’s CPU, RAM usage and Signaling Server’s thread queues, dBs connection pool size. You can also do some User Operations.
  • Web Client supports Chrome, Firefox, and IE-10.
  • Android Client can make secure voice and video calls and send secure IMs.
  • IOS Client can make secure voice and video calls and send secure IMs.
  • File Encryption encrypts any file which can only be opened by target
  • Lawful Interception can listen any communication by a lawful request


How we differ from Crypto Phones

When discussing secure communication, the first thing that comes to mind is usually crypto phones.

  • Nova MSP provides secure communication and quality service, and is device and Operating System independent. Crypto phones are device-dependent and need a compatible client device to establish a secure call.
  • With Nova MSP, new users only need a smartcard and they can be online in just a couple of minutes. Conversely, new users of crypto phones need to first obtain a new crypto phone.
  • RSA keys are generated by the smartcard itself. Therefore, there is no way for an unwanted person to find out keys.
  • Nova MSP can run on any Android or iOS smart phones. Smartphones and their related products develop very quickly, and it is very hard for crypto phones to keep up with the changing technology.
