My previous article on IoT “P2P” cameras couldn’t go into much detail on the PPPP protocol. However, there is already lots of security research on and around that protocol, and I have a feeling that there is way more to come. There are pieces of information on the protocol scattered throughout the web, yet every one approaching from a very specific narrow angle. This is my attempt at creating an overview so that other people don’t need to start from scratch. While the protocol can in principle be used by any kind of device, it is mostly being used for network-connected cameras. It isn’t really peer-to-peer as advertised but rather relies on central servers, yet the protocol allows to transfer the bulk of data via a direct connection between the client and the device. It’s hard to tell how many users there are but there are lots of apps, I’m sure that I haven’t found all of them. There are other protocols with similar approaches being used for the same goal. One is used by ThroughTek’s Kalay Platform which has the interesting string “Charlie is the designer of P2P!!” in its codebase (32 bytes long, seems to be used as “encryption” key for some non-critical
