My group and me are having problems with some thing. We would like to ask if someone can answered us with this, thanks.
1-Can an Informorph use the Multi Taskin mental augmentation? Maybe as a software upgrade (like the others on Transhuman) or installint the upgrade on a server. This question comes because the Upgrade Panopticon (Trans human pag 141) says "increase this to 5 locations if the character also has multi-tasking".
2-The Emergency Back Up Plug in (trans-human pag 140) says that the copy of the ego is transmitted using the mesh and "To prevent ego theft, the backup copies are transmitted using quantum cryptography". The rules about quantum cryptography say that you only can use emtabling 2 or more comunicators, so you cant use in the mesh because it use different receivers. Could you explain me this please? Because I'm a little lost. Is like you could use quamtum crptograpy with your mesh implants
3-Can you install a second cortical Stack in your morph? As backup if your main one is stored
4-If you are ghostriding with an infomorph on a ghosrider module, are you stored on a cortical stack? Maybe the ghostrider module have Its own cortical stack or the carrier's cortical stack can store
I have doubts about if to do egocasting is neccesary to have the two quamtum entabled farcasters because in the core book they are talking about to do a egocasting from a hipercorp company to a private individual in Vesta, so it is difficult to believe that they have entabled computers if the are different parts
Welcome! These forums will be deactivated by the end of this year. The conversation continues in a new morph over on Discord! Please join us there for a more active conversation and the occasional opportunity to ask developers questions directly! Go to the PS+ Discord Server.

1: No reason why not.
1: No reason why not.
2: Good question. Probably a goof on someone's part. Resolve it at your table as you see fit. I'd just say that instead of quantum crypto, the backups are transmitted with ginormous one-time pads. Even with a matroiska brain made out of quantum computers, you'd still need an infeasibly long time to crack it, on the order of centuries. The net effect remains the same, in that breaking the crypto requires subverting one of the two ends.
3: I see no reason why you can't. You'd probably want to equip both of your stacks with dead switches, though, to fire if the other one is popped while it's still intact. And don't forget to tell your teammates! You don't want to hide a second stack in your pelvis and get cut in half, for your team to pop one and forget about the other. (The 'secondary' (tertiary, etcetera,) should probably trigger their killswitches if they get too far from the primary while it's active, too.)
4: I would say that you're stored on the morph's primary (and any secondary, tertiary, etcetera,) cortical stack, unless you went the extra mile to get a different cortical stack just for the ghostrider. Remember, if you have the multiple-personality upgrade, it backs up to one stack, too.
As for the egocasting... Remember that egocasting is just data, at the fundamental level. You can use a quantum-entangled FTL communicator and burn your qubits to farcast, you can use neutrino comms to farcast, you can use regular old radio waves to farcast, you can farcast by mailing your stack to someone via courier, you can farcast by transmitting your ego as binary code rendered as morse code and transmitted as electrical pulses down a length of copper wire if you are so inclined!

Well, in pag 254 the rules say that a Quamtum Computer can break a Public Key encryption in a timeframe of a week, so if you are using a non Quamtum cypher to encode the data, it is relative easy to get the data....
Also, what is the meaning of the data in your spoiler?

Re: #2, quantum cryptography
Re: #2, [url=http://en.wikipedia.org/wiki/Quantum_cryptography]quantum cryptography[/url] is different from quantum entanglement and QE communicators. The former is a method of software encryption and the latter a way to transmit data between two points without taking into account the distance between the two points.

To use quamtum cryptography you need to entagle two ore more devices in the same place. It is used in Quamtum Farcasters. My problem is that you cant use it on the Mesh as the plug-in says, because you cant "entagle" all the places where you infomoprh (maybe you are on a server)

You're right! I misunderstood the post. I think Shadowdragon has the right way of it.

Quantum computers cannot break one-time pads. One-time pads, so long as they are only used once, are unbreakable regardless of time and computing power. One-time pads are distinct from public key encryption.

I'm not an expert in any of
I'm not an expert in any of this, but this is what I remember:
Quantum crypto does not use entanglement; IIRC information to be transmitted is encoded in properties of the transmission medium that exhibit quantum superposition, I think current research systems use some property of photons for this, whether in a laser or fibre-optic type thing. If a third-party tries to covertly intercept the communication, the quantum superposition collapses and the message is lost to the expected recipient, tipping them off that they're being spied on.
FTL communication using quantum entanglement is, according to a physicist friend of mine, not actually a thing. I'm not a physicist, so I can't explain why not but quantum entanglement, while it is funky, still maintains the "no information transfer faster than the speed of light" rule.
As to quantum computers breaking codes, yeah, that's for asymmetric encryption, which is what anything dealing with "public keys" talks about; they're built on certain thought-to-be-hard math problems that we have a quantum algorithm to solve. One-time pads are not susceptible to that. I mean, the books don't mention them being used, so I'd assume the practical issues using them (perfect randomness is hard) haven't been solved in EP.

When I think of egocasting or
When I think of egocasting or any interhab comms over interplanetary distances, I don't imagine that as mesh use, I see that as point-to-point comms. Given the general need for encryption, I think that all major habs would have shared entangled farcasters exactly for that purpose. Small habs will most likely not have entagled devices with all other habs, but by using the larger habs as comm hubs, they could have encrypted traffic (obviously the hub is a point of risk, but that's how it is).
