In order to achieve the highest level of protection, signaled by a green indicator, the two parties need to exchange PEP-generated "safe words" over the phone. Once this handshake is confirmed, the communication is protected against all known attacks, the PEP developers said on the project's Indiegogo page.
The technology does not rely on centralized infrastructure and uses peer-to-peer technology for anonymous transport. When both parties use it, it's not just the content of messages that get encrypted, but metadata like the subject line in the case of emails.
The current goal of the crowdfunding campaign is to raise $50,000, which will help with the development of the PEP implementation for Android. However, more funds will be needed to speed up support for different platforms, communication tools and encryption protocols.
