28 Sep Signal Uses Controversial Intel Feature as Privacy Asset
Earlier this week, messaging app Signal revealed plans to use Intel’s Software Guard Extensions (SGX) as an additional asset for privacy protection.
SGX has been previously criticized for potentially being a route to unbreakable DRM, and for limiting the user’s freedom on his own machine. However, the open-source and peer-reviewed app uses it as a secure middleman when importing contacts so that Signal would not ever have to handle your contacts. This eliminates the possibility of compromise from the app, or the company’s end in case of a breach.
Most experts believe that Signal is the best messaging app in terms of privacy, and may even be better than Confide, which is used by White House aides for its security features.
