Abstract
Verification of privacy of Web Real-Time Communications (WebRTC) media channels via corresponding WebRTC data channels, and related methods, systems, and computer-readable media are disclosed. In this regard, in one embodiment, a method for verifying privacy of a WebRTC media channel comprises establishing the WebRTC media channel between first and second WebRTC clients using a keying material. The method further comprises establishing a corresponding WebRTC data channel between the first and second WebRTC clients using the keying material, and negotiating, in the WebRTC data channel, a cryptographic key exchange. The method also comprises generating a first and a second Short Authentication String (SAS) based on the cryptographic key exchange in the WebRTC data channel. The method further comprises displaying the first SAS and the second SAS, such that a mismatch between the first SAS and the second SAS indicates an existence of a man-in-the-middle (MitM) attacker.
