And just how are you delivering the key material for your one-time pad?
- shermantanktop 2y agoIt's OTPs all the way down.
- Jerrrrrrry 2y agoDoesn't matter. Literally, could be entangled quantum photo-carrier pigeons. x ⊕ y = z z ⊕ x = y y ⊕ z = x Assuming another Out-of-Bound communication channel, all communication channels are provably safe. https://en.wikipedia.org/wiki/One-time_pad#Perfect_secrecy https://en.wikipedia.org/wiki/One-time_pad#Perfect_secrecy
- echoangle 2y agoIf you have the Out-of-Band communication channel to transmit your OTP (which has to have the same size as the data itself), you can just transmit the data using this method and skip the other channel.
- teddyh 2y agoTrue, but you might have a secure OOB channel for a limited time. In that case, you can transfer an arbitrarily large OTP over the secure channel, to be used later, in small pieces, when you do not have a secure channel available.
