When it comes to cryptographic protocols, a formal security proof is the ultimate hallmark of quality. German researchers now provide such a proof for the Ibex protocol, confirming that Threema’s security is based on a rock-solid foundation.
In modern democracy, the press plays such an essential role that it is often described as the “Fourth Estate.” Without independent news coverage, and thus without the watchdog function of the press, political processes could not be reviewed by the public.
All good things come in threes: the latest Threema update for iOS introduces profile pictures in push notifications, contacts in the Share Sheet, and Siri suggestions, thereby improving the app’s OS integration quite a bit.
In addition to the EU’s so-called “chat control,” there’s another European draft legislation that uses child protection as a pretext for full-scale surveillance of chat communication without probable cause: the UK’s Online Safety Bill. Together with other messaging services, we take a firm stand against this legislative proposal.
Just like you occasionally replace old photos on the wall with new ones, apps also need a fresh touch every once in a while. Now, Threema’s iOS app presents itself in a new look: since the 4.8 update, the user interface has been renewed step by step. With Threema 5.0 for iOS, the complete rewrite of the chat view has now received its finishing stroke.
A group chat with you as the only member? What might sound useless at first is a handy feature in Threema: this “group” can be used as a versatile chat for personal notes. Find out in this blog post in what situations this empty group chat is particularly useful.
Last year, a student at the Department of Computer Science at ETH Zurich wrote his master’s thesis on Threema’s communication protocol. ETH Zurich has now published his work as a paper/preprint. The presented findings have been addressed or no longer apply to Threema’s current communication protocol “Ibex.” None of them ever had any considerable real-world impact.
