Key pre-distribution schemes are a favored solution for establishing secure communication in sensor networks. Often viewed as the safest way to bootstrap trust, the main drawback is seen to be the large storage overhead imposed on resource-constrained devices and also these schemes are quite insecure because pre-loading global secrets onto exposed devices strengthens the incentive for attackers...
The core of security proofs quantum key distribution (QKD) is the estimation a parameter that determines amount privacy amplification users need to apply in order distill secret key. To estimate this using observed data, one needs concentration inequalities such as random sampling theory or Azuma's inequality. latter can be straightforwardly employed wider class QKD protocols, including those d...

With the help of a simple quantum key distribution (QKD) scheme, we discuss the relation between BB84-type protocols and two-step-type ones. It is shown that they have the same essence, i.e., information-splitting. More specifically, the similarity between them includes (1) the carrier state is split into two parts which will be sent one by one; (2) the possible states of each quantum part are ...
To enable global scale quantum key distribution (QKD), satellite based systems are the most promising approach. So far, free-space QKD has already been demonstrated on communication channels with attenuation comparable to satellite downlinks, and classical laser communications with satellites and aircrafts is heavily explored. Here, combining both these challenges, we demonstrate an aircraft to...
