Signal Working on Advanced Method to Keep Contacts Secret
The developer of secure messaging app Signal is working on an advanced new technique to fully encrypt and anonymize the process of contact discovery (matching a user's phone contacts with existing Signal users.) Although Signal currently anonymizes this data and says they do not store it, it is data that could theoretically be intercepted and de-anonymized by a hacker or government agency. The new method addresses these concerns using secure enclave technology built into modern Intel chips. The technique allows the client app (which is open-source) to run the contact-matching code within a secure enclave on Signal's servers. The technology also allows the client app to confirm that the contact-matching code is secure from observation by other code on Signal's servers, and has not been tampered with. That way, even if a hacker or government agency infiltrates Signal's servers, they would not be able to tell which contacts a Signal user has matched. The technology was originally developed by Intel to enable DRM for copyrighted video content, but Signal is using the technology in a novel way. The new feature is expected to roll out in the next few months.

Qualcomm has taken yet more action against Apple, which it alleges stole trade secrets and offered them to Intel in a bid to improve Intel's modems. This year's iPhones rely solely on Intel modems, rather the a mix of modems from Intel and Qualcomm, in part because Apple and Qualcomm are locked in a legal dispute over patents and licensing fees.
