ReliaSpeak™ SEM1
CryptoPhone

Digital voice encryption, Support for GSM/UMTS voice, VoLTE,
and VoIP encrypted calls

  • Qualcomm 660 AIE CPU, High-performance Android smartphone.
  • Supports encrypted calls over VoLTE and standard GSM/UMTS cellular voice channels.
  • Supports encrypted calls over WeChat, WhatsApp and other public VoIP channels.
  • Encrypted calls can be interconnected with landline phone (using ReliaSpeak™ Landline Encryptor).
  • End-to-end digital voice encryption with ECDH/AES256 cryptographic algorithm
  • Encrypted calls are not restricted by carriers and regions.​
  • Integrates Multiple security features such as SMS encryption, etc.​

How is encrypted call implemented?

ReliaSpeak™ Crypto Phone integrates ReliaSpeak™ digital voice encryption technology. During encrypted calls, it first compresses and encrypts the user’s voice, and uses advanced AMSI modulation technology to convert the encrypted digital voice stream into an analog audio signal, which is then handed over to the telephone program for speech coding and cellular network communication, thereby, implements a source-level end-to-end encrypted call that is independent of the voice channel.

The most powerful call privacy protection

Protecting against cellular network eavesdropping and Trojan eavesdropping

  • Uses digital encryption technology instead of analog scrambling technology, Encrypted voice does not have any speech property.
  • End-to-end and real-time negotiation of secure key does not rely on carriers or third-party security services.
  • Uses AES-256-CTR algorithm, real-time secret key replacement is up to 5 times per second.
  • Voice source encryption based on underlying drive technology, avoids original clear voice being stolen by any spyware.

Using your own Cryptographic Algorithms

Meets your specific security requirement

Flexibility

Customer can develop all security solutions including key management, key exchange, encryption algorithm, etc.

Independent

We provided a framework, API documentation, and some executable source code.
Customer only needs to develop a corresponding system service or apps according to the provided program framework and run it in the specified path to implement algorithm replacement.

Verifiable

Customers can verify whether the voice is encrypted by their own key and algorithm through a simple communication test.

Encrypted calls anytime, anywhere

Whenever and wherever you are, you can find a suitable way to make encrypted calls, including 2G/3G cellular voice, VoLTE or public VoIP

Make Encrypted calls to Landline

Compatible with the ReliaSpeakTM Landline Encyptor,  Make encrypted communication between landline and mobile phone possible.

Easy to use

No registration, no setup, direct use

  • Call remote user using cellular voice or VoIP APP*.
  • The remote user answers the call and the two parties start talking (normal communication, clear voice).
  • Either side can press the floating "lock" button to start an encrypted connection.
  • After hearing the indication voice “now is in encrypted communication”, you can start encrypted calls.
  • In encrypted communication, either side can press the floating "lock" button to return to the normal communication.
  • In normal and encrypted communication, users can hang up the phone directly.
