KEAV is a new computer-implemented method to ensure secure VoiP and IoT communications.

This technology allows a latency reduction of 26% when compared to the Public Key Service (PKI)-based systems, while offering a totally decentralised authentication model and mitigating the risk of Man-in-the-middle (MitM) attacks.



The current systems use PKI systems that are costly, have a big latency and constitute a centralized solution with a single point of failure.

KEAV was designed and implemented as a novel technology for secure peer-to-peer data exchange. Combining an improved version of ZRTP method with multy-party computation (MPC), KEAV is a competitive cybersecurity solution for VoiP and IoT applications.



Main Advantages

  • 100% decentralised solution – not exposed to a single point of failure such as the state-of-art of the PKI systems
  • Enhanced cybersecurity – improving already reliable cryptographic ZRTP protocol
  • Excellent performance – powered by two lightweight protocols
  • Secure end-to-end data exchange – enabled by the use of sMPC
  • Tunable security level – users can adjust the trade-off between security and runtime



  • VoiP calls
  • Internet of Things, namely in small-sized devices and in sensors without touchscreens or buttons.
