Information security has always been a critical issue in wireless networks. Apart from other
secure techniques, covert communication emerges as a potential solution to security for …

Recent work has established that when transmitter Alice wishes to communicate reliably to
recipient Bob without detection by warden Willie, with additive white Gaussian noise …

在泛在网络环境下, 隐蔽通道通过修改系统共享资源, 绕开系统的安全策略传输隐蔽信息,
给计算机和网络系统造成了严重的安全威胁. 针对此问题, 主要从度量, 构建和检测3 …

The laws of quantum physics endow superior performance and security for information
processing: quantum sensing harnesses nonclassical resources to enable measurement …

The recent square root law (SRL) for covert communication demonstrates that Alice can
reliably transmit O (√ n) bits to Bob in n uses of an additive white Gaussian noise (AWGN) …

We study the first-and second-order asymptotics of covert communication over binary-input
discrete memoryless channels for three different covertness metrics and under maximum …

In covert communication, Alice tries to communicate with Bob without being detected by a
warden Willie. When the distance between Alice and Bob becomes large compared with the …

We consider a scenario in which K transmitters attempt to communicate covert messages
reliably to a legitimate receiver over a discrete memoryless multiple-access channel (MAC) …

Spin-based, quantum-photonics promise to realize distributed quantum computing and
quantum networks. The performance depends on an efficient entanglement distribution …

We investigate the fundamental limit of quantumsecure covert communication over the lossy
thermal noise bosonic channel, the quantum-mechanical model underlying many practical …
