emanations

Humans focus on design flaws and weird hardware bugs like cryptographic side-channels from electromagnetic emanations Turns out finding all the bugs is really hard.

It's not infeasible to have detectors to monitor emanations yielding a whole new swath of privacy issues.

Most of these attacks can be mitigated through physical separation; the official standards specify allowable signal strengths at perimeter for spurious emanations.

They are not talking about catching emanations from sound codecs or key strokes they are talking about CPU instructions for crying out loud.

These are emanations from vulcan warpships travelling through our solar system.

Keylogging by acoustic emanations is a well researched technique, I just think it could be a feature if we made the keyboard right.

Just as mysterious emanations from celestial objects were once thought to shape character (with a role reserved for free will), so today mysterious emanations from molecular objects are thought to do the same (with a role reserved for the environment).

This paper did not introduce any new kind of side channel, and extensively cites literature in which other people introduced (and often demonstrated) the side channel and emanations risks.

I wouldn't be surprised if there are other esoteric techniques that somehow allow NSA to monitor emanations through an intact fiber optic cable and its shielding.

I'd wager that most of the great things we use today started as nearly ephemeral emanations from someone's mind, often late at night, or helped along by a snifter of brandy.

The attack was using an antenna (which listened to electromagnetic emanations rather than sound, but that's a detail, it is also possible to do that with power consumption, timing…) which was simply put near the screen of the phone.

Douglas wrote “…specific guarantees in the Bill of Rights have penumbras, formed by emanations from those guarantees that help give them life and substance.

People can joke about all the "penumbras and emanations" silliness, but the fact remains that there's explicit support for protecting rights not explicitly enumerated.

In Griswold, Justice Douglas didn't rely on "penumbras" and "emanations" despite having clear Constitutional text to hang his hat on!
