How exactly are the telepathic transmissions between Murphy , Seamus, and the rest actually transmitted? 
Via Carrier wave of some sort?   

How is it that nobody ever seems to be able to intercept or at least detect the fact that the protagonists are secretly talking to each other?


Even if the transmission are magically completely encoded and undecipherable, it could be considered rude to be caught 'whispering behind your hosts backs"


"We don't know what you are signaling to each other but we'd appreciate it if you'd stop doing it right in front of our faces...very suspicious"

It pretty much has to be encoded radio signals. If it were something like the Tanglenet ala "Escape from Terra", it wouldn't be limited by the speed of light, and they would still be in contact with Pixie Girl.

I presume some kind of radio link.  If spread spectrum it may be undetectable over the ambient noise for anyone without the spreading sequence.  And safe bet it uses some good encryption, likely with a session key.

Seamus has demonstrated the ability to hack on contact. Since they're sitting side by side, they may have opted to use a landline.

Nod.

Note, in a very early strip Seamus was concerned that even his communications security could be broken.

While that was centuries ago (in universe time) and communication security has likely been improved, our heroes are still taking a calculated risk.

Although the "land line link" is possible.

Any encryption system can, in theory, be cracked.  With a long enough key the chances of that being done before the value of cracking decays to near zero can be very low.  Of course that presumes the enemy doesn't have a viable quantum computer that can beat P != NP for the relevant algorithm.

Bzzt! Wrong. You cannot crack One-time Pad, which Seamus and his compatriots IMHO should  be using: They can exchange electronic "pads" beforehand securely and if someone can pwn their brains, the fight is already lost.

Radio link is interceptable and if you're un-diplomatic enough, you could raise the issue. But you're probably not that stupid, even if the intercepted messaging resembles white noise.

Great one-time pad story.  Independant of the criminal investigation, the CIA was able to confirm that Ethel and Julius Rosenberg were, in fact, Soviet spies.  This was because the CIA was able to read many of their transmissions, despite the fact that they used a one-time pad.

You see, they reused the same key several times, apparently not quite understanding what a one-time pad is.

There encounter suits could have a ring of low energy lasers that encode their transmissions directly toward each other, and only toward each other, making interception virtually impossible. Even without encounter suits, they could still have said tech embedded in their bodies.
Stupid criminals put on a mask and rob people with a gun.
Smart criminals put on a suit, call themselves politicians, and rob people with writ of law.

Do you mean like hologram emitters?

Not what I had in mind, but they could be used to color shift a small specs on their holographic skin to transmit a low bandwidth signal capable of handling texting.
