Now that they've finished building a robot capable of making cakes, MIT's researchers can get on with the serious business of improving our wireless security. In a new study it reveals a technique dubbed tamper-evident pairing that stops so-called man-in-the-middle attacks. Put simply, a hacker intercepts your wireless communications, reads it and passes it onto the recipient, pretending to be you.
