The Tor upgrade improves the technology that is now aging rapidly and pays great attention to security and encryption
While some people still associate the Tor network with exclusively criminal and dark web, it is actually increasingly used by publishers like Facebook and the New York Times for avoid censorship in certain countries, along with many generic users who want protect their privacy; but the technology behind Tor's more than ten years and governments and hackers are attacking its systems and for this reason the project has announced its intention to implement a new generation of improved security services.
The Tor update
The working group behind Tor has been working on the update for four years strengthen security and keep anonymous data and now an alpha version is available.
Many of Tor's users will hardly notice the differences, though the new .onion domain names will be longer. The Tor project said that as the code stabilizes, other features will be added in the future, including advanced client authorization, improved security algorithms and offline service keys.
State-of-the-art encryption for Tor
On the cryptography side, the group focused on cutting-edge cryptographic algorithms and improved authentication schemes. On the protocol side, they redesigned the directory system to defend the system against information leaks and reduce the attackable global surface. With this new generation design, the completely private onion address.
While the bugs are removed and the additional features are implemented, the traditional onion system remains the default option, even if the plan is to overcome the oldest technology in a few years.
In February, a hacker associated with the hacktivist group Anonymous managed to send about 20 percent of the Dark Web offline, apparently in reaction to the discovery of gigabytes of child pornography.
