Multi-channel broadcast encryption [PDF]

open access: yesProceedings of the 8th ACM SIGSAC symposium on Information, computer and communications security, 2013
Broadcast encryption aims at sending a content to a large arbitrary group of users at once. Currently, the most efficient schemes provide constant-size headers, that encapsulate ephemeral session keys under which the payload is encrypted. However, in practice, and namely for pay-TV, providers have to send various contents to different groups of users ...

How Much Feedback Is Required for TDD Multi-Antenna Broadcast Channels with User Selection?

open access: yesEURASIP Journal on Advances in Signal Processing, 2010
The enormous gains in a multi-antenna transmitter broadcast channel require the Channel State Information at the Transmitter (CSIT). Although the fundamental question "How much feedback is required for a broadcast channel?" has been treated in the ...

Aggregating distributed energy resources for grid flexibility services: A distributed game theoretic approach

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView., 2023
Abstract We propose a hierarchical energy management scheme for aggregating Distributed Energy Resources (DERs) for grid flexibility services. To prevent a direct participation of numerous prosumers in the wholesale electricity market, aggregators, as self‐interest agents in our scheme, incentivize prosumers to provide flexibility. We firstly model the

Topological Interference Management for Wireless Networks

open access: yesIEEE Access, 2018
Topological interference management (TIM) is considered under the condition that only topology-related information is available at the transmitters, but no accurate channel state information is fed back to them, which is capable of significantly reducing

Erasure Broadcast Channels With Intermittent Feedback [PDF]

open access: yesIEEE Transactions on Communications, 2021
Achievable data rates in wireless systems rely heavily on the available channel state information (CSI) throughout the network. However, feedback links, which provide this information, are scarce, unreliable, and subject to security threats. In this work, we study the impact of having intermittent feedback links on the capacity region of the canonical ...

Multichannel Broadcast Based on Home Channel for Cognitive Radio Sensor Networks

open access: yesThe Scientific World Journal, 2014
Considering the limited resources and the dynamic spectrum distribution in the cognitive radio sensor networks (CRSN), a half-duplex Multichannel broadcast protocol for CRSN is presented based on the home channel.
