I wasn’t worried about the communicators’ encryption. I’d only put them together last spring. It wasn’t as if they were old League technology that everyone had analyzed thirty years ago.
Maybe I should have been worried more. The communicators were based on the roachbots, and Grandpa had designed the first versions of the roachbots in the 1950’s as mobile bugging devices.
I’d updated them substantially over the past year though. Grandpa’s design survived only in the most general terms.
All the details of the current systems were mine.
Of course, the communicators still connected to the League’s old alert system. That might be a vulnerability.
