Secure message transmission in the presence of a fully generalised adversary

open access: yesJournal of Mathematical Cryptology, 2015
We investigate the problem of secure message transmission in the presence of a `fully generalised' adversary, who disrupts and listens to separate sets of communication wires.

Can Two-Way Direct Communication Protocols Be Considered Secure?

open access: yesNanoscale Research Letters, 2017
We consider attacks on two-way quantum key distribution protocols in which an undetectable eavesdropper copies all messages in the message mode. We show that under the attacks, there is no disturbance in the message mode and that the mutual information ...

Methods of increasing two-way transmission capacity of wireless ad hoc networks

open access: yesEURASIP Journal on Wireless Communications and Networking, 2018
Two-way communication is required to support control functions like packet acknowledgement and channel feedback. Most previous works on the transmission capacity of wireless ad hoc networks, however, focused on one-way communication; reverse ...
