Finally, we discuss how CCCP can be improved by designing specialized transcribers and carefully selected checksum dictionaries, and how it can be integrated with existing Crypto Phones to bolster their security and usability. They also show that CCCP may help reduce the likelihood of voice MITM. Our study results demonstrate that, by using our automated checksum comparison, CCCP can completely resist data MITM, while significantly reducing human errors in the benign case compared to the traditional approach. To evaluate the security and usability benefits of CCCP, we then design and conduct an online user study that mimics a realistic VoIP scenario, and collect and transcribe a comprehensive data set spoken by a wide variety of speakers in real-life conditions. Automating checksum comparisons offers many key advantages over traditional designs: (1) the chances of data MITM due to human errors and "click-through" could be highly reduced (even eliminated) (2) longer checksums can be utilized, which increases the protocol security against data MITM (3) users' cognitive burden is reduced due to the need to perform only a single task, thereby lowering the potential of human errors.Īs a main component of CCCP, we first design and implement an automated checksum comparison tool based on standard Speech to Text engines. CCCP simply requires the user to announce the checksum to the other party-the system automatically transcribes the spoken checksum and performs the comparison. We introduce Closed Captioning Crypto Phones (CCCP), that remove the human user from the loop of checksum comparison by utilizing speech transcription. Further, human errors under benign settings undermine usability since legitimate calls would often need to be rejected. However, research shows that both tasks are prone to human errors making Crypto Phones highly vulnerable to MITM attacks, especially to data MITM given the prominence of these attacks.
What is cccp settings verification#
They require end users to perform: (1) checksum comparison to detect traditional data-based man-in-the-middle (data MITM) attacks, and, optionally, (2) speaker verification to detect sophisticated voice-based man-in-the-middle (voice MITM) attacks. And as I already said, I haven't had the chance to compare the latest version properly yet.Īlso, chill down a bit, will you? While VLC likes to advertise itself to anime watchers, it's an audience that on average cares a lot more about high quality playback than many others.Crypto Phones aim to establish end-to-end secure voice (and text) communications based on human-centric (usually) short checksum validation. We were talking about dithering though (which that comparison also demonstrates), so unless the matrix issue was directly linked to the dithering issues it's not really relevant (and I didn't mention it either). >Last version, the matrix colors were wrong, as clearly explained on the release page, so it's soooo great to compare with it.
What is cccp settings software#
Unless you subscribe to RMS' worldviews about proprietary software (in which case you wouldn't be using Windows to begin with), I don't see a reason not to use it if you have enough interest in high quality playback. madVR is proprietary, yes, but it also happens to be the most advanced video renderer in existence. I'm not really sure about the non-component parts (the installer and settings panel), though.
Installation and basic configuration (the average user really doesn't need any more than that) madVR on top of that with a guide (and there are plenty) is five-ten minutes of effort, but as I said, it's not a necessity by any means.Īll the playback components in CCCP are FOSS with the exception of Haali Media Splitter, which is more of a fallback at this point. I've been saying this for a good while now but you keep talking like I said madVR would be a must and use that as a basis to claim that VLC is "just simpler".
And I said that I recommend madVR as an optional component, since CCCP already provides high quality playback out of the box. Especially for most people.ĬCCP requires no configuration. CCCP and madVR configuration is not a five-ten minutes of effort.
