Secure transmission of correlated sources over broadcast channels with ultra-low latency
EURASIP Journal on Wireless Communications and Networking, 2019 Correlated sources passing through broadcast channels is considered in this paper. Each receiver has access to correlated source side information and each source at the sender is kept secret from the unintended receiver.

Entropy, 2015 In this paper, the general wiretap channel with channel state information (CSI) at the transmitter and noiseless feedback is investigated, where the feedback is from the legitimate receiver to the transmitter, and the CSI is available at the transmitter ...

New Results on Multiple-Input Multiple-Output Broadcast Channels with Confidential Messages [PDF]
, 2011 This paper presents two new results on multiple-input multiple-output (MIMO) Gaussian broadcast channels with confidential messages. First, the problem of the MIMO Gaussian wiretap channel is revisited.

Source-Channel Secrecy with Causal Disclosure [PDF]
, 2012 Imperfect secrecy in communication systems is investigated. Instead of using equivocation as a measure of secrecy, the distortion that an eavesdropper incurs in producing an estimate of the source sequence is examined.

Secure Lossy Source Coding with Side Information at the Decoders [PDF]
, 2010 This paper investigates the problem of secure lossy source coding in the presence of an eavesdropper with arbitrary correlated side informations at the legitimate decoder (referred to as Bob) and the eavesdropper (referred to as Eve).

On Secure Transmission over Parallel Relay Eavesdropper Channel [PDF]
, 2010 We study a four terminal parallel relay-eavesdropper channel which consists of multiple independent relay-eavesdropper channels as subchannels. For the discrete memoryless case, we establish inner and outer bounds on the rate-equivocation region.

On the Construction of Polar Codes for Achieving the Capacity of Marginal Channels
, 2017 Achieving security against adversaries with unlimited computational power is of great interest in a communication scenario. Since polar codes are capacity achieving codes with low encoding-decoding complexity and they can approach perfect secrecy rates ...

Performance Analysis and Design of Two Edge Type LDPC Codes for the BEC Wiretap Channel
, 2011 We consider transmission over a wiretap channel where both the main channel and the wiretapper's channel are Binary Erasure Channels (BEC). We propose a code construction method using two edge type LDPC codes based on the coset encoding scheme.

Cooperation with an Untrusted Relay: A Secrecy Perspective
, 2009 We consider the communication scenario where a source-destination pair wishes to keep the information secret from a relay node despite wanting to enlist its help.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.
