Classical-quantum arbitrarily varying wiretap channel: Secret message transmission under jamming attacks
Classical-quantum arbitrarily varying wiretap channel: Secret message transmission under jamming attacks
We analyze arbitrarily varying classical-quantum wiretap channels. These channels are subject to two attacks at the same time: one passive (eavesdropping), and one active (jamming). We progress on previous works [5] and [6] by introducing a reduced class of allowed codes that fulfills a more stringent secrecy requirement than earlier …
