We all know that our cell phones constantly give our location away to our mobile network operators; that’s how they work. A group of researchers has figured out a way to fix that. “Pretty Good Phone Privacy” (PGPP) protects both user identity and user location using the existing cellular networks. It protects users from fake cell phone towers (IMSI-catchers) and surveillance by cell providers.
It’s a clever system. The players are the user, a traditional mobile network operator (MNO) like AT&T or Verizon, and a new mobile virtual network operator (MVNO). MVNOs aren’t new. They’re intermediaries like Cricket and Boost.
Here’s how it works:
The MNO doesn’t have to modify its system in any way. The PGPP MVNO implementation is in software. The user’s traffic is sent to the MVNO gateway and then out onto the Internet, potentially even using a VPN.
All connectivity is data connectivity in cell networks today. The user can choose to be data-only (e.g., use Signal for voice), or use the MVNO or a third party for VoIP service that will look just like normal telephony.
The group prototyped and tested everything with real phones in the lab. Their approach adds essentially zero latency, and doesn’t introduce any new bottlenecks, so it doesn’t have performance/scalability problems like most anonymity networks. The service could handle tens of millions of users on a single server, because it only has to do infrequent authentication, though for resilience you’d probably run more.
The paper is here.
Sup, yo.
Its award szn here at r/NYYankees. Below are 2 polls, one for actual New York Yankees stuff, and one for sub-specific stuff. I'll leave these up for like idk a week or so, completely forget about them, have someone be like "so uhh...u/aweinschenker, when are we getting those results?", and then post them shortly after that.
Vote or Die motherfuckers.
