Hong Kong Protesters Using Mesh Messaging App China Can't Block: Usage Up 3685%

An anonymous reader quotes Forbes: How do you communicate when the government censors the internet? With a peer-to-peer mesh broadcasting network that doesn't use the internet.

That's exactly what Hong Kong pro-democracy protesters are doing now, thanks to San Francisco startup Bridgefy's Bluetooth-based messaging app. The protesters can communicate with each other — and the public — using no persistent managed network... While you can chat privately with contacts, you can also broadcast to anyone within range, even if they are not a contact.

That's clearly an ideal scenario for protesters who are trying to reach people but cannot use traditional SMS texting, email, or the undisputed uber-app of China: WeChat. All of them are monitored by the state.

Wednesday another article in Forbes confirmed with Bridgefy that their app uses end-to-end RSA encryption -- though an associate professor at the Johns Hopkins Information Security Institute warns in the same article about the possibility of the Chinese government demanding that telecom providers hand over a list of all users running the app and where they're located.

Forbes also notes that "police could sign up to Bridgefy and, at the very least, cause confusion by flooding the network with fake broadcasts" -- or even use the app to spread privacy-compromising malware. "But if they're willing to accept the risk, Bridgefy could remain a useful tool for communicating and organizing in extreme situations."
