Secrecy results for compound wiretap channels
We derive a lower bound on the secrecy capacity of the compound wiretap channel with channel state information at the transmitter which matches the general upper bound on the secrecy capacity of general compound wiretap channels given by Liang et al. and thus establishing a full coding theorem in this case. We achieve this with a stronger secrecy criterion and the maximum error probability crit...
متن کاملSecrecy capacities of compound quantum wiretap channels and applications
We determine the secrecy capacity of the compound channel with quantum wiretapper and channel state information at the transmitter. Moreover, we derive a lower bound on the secrecy capacity of this channel without channel state information and determine the secrecy capacity of the compound classical-quantum wiretap channel with channel state information at the transmitter. We use this result to...
متن کاملCompound Wiretap Channels
This paper considers the compound wiretap channel, which generalizes Wyner’s wiretap model to allow the channels to the (legitimate) receiver and to the eavesdropper to take a number of possible states. No matter which states occur, the transmitter guarantees that the receiver decodes its message and that the eavesdropper is kept in full ignorance about the message. The compound wiretap channel...
متن کاملOn Ergodic Secrecy Capacity for Gaussian MISO Wiretap Channels
1 A Gaussian multiple-input single-output (MISO) wiretap channel model is considered, where there exists a transmitter equipped with multiple antennas, a legitimate receiver and an eavesdropper each equipped with a single antenna. We study the problem of finding the optimal input covariance that achieves ergodic secrecy capacity subject to a power constraint where only statistical information a...
متن کاملCapacity results for classes of wiretap channels
We consider two communication systems which are time-discrete and memoryless, both depend on a state, in terms of information-theoretic secure data transmission. The compound channel consists of a finite or infinite set of channels which is known to both the sender and the receiver, but unfortunately it is not known which channel is in use for any codeword transmission. In contrast the state of...
