Semantic Security for Quantum Wiretap Channels [PDF]
2020 IEEE International Symposium on Information Theory (ISIT), 2020 We consider the problem of semantic security via classical-quantum and quantum wiretap channels and use explicit constructions to transform a non-secure code into a semantically secure code, achieving capacity by means of biregular irreducible functions. Explicit parameters in finite regimes can be extracted from theorems.

Private Information Retrieval Through Wiretap Channel II: Privacy Meets Security [PDF]
IEEE Transactions on Information Theory, 2018 We consider the problem of private information retrieval through wiretap channel II (PIR-WTC-II). In PIR-WTC-II, a user wants to retrieve a single message (file) privately out of M messages, which are stored in N replicated and non-communicating ...

The Secrecy Capacity of the MIMO Wiretap Channel [PDF]
IEEE Transactions on Information Theory, 2008 We consider the MIMO wiretap channel, that is a MIMO broadcast channel where the transmitter sends some confidential information to one user which is a legitimate receiver, while the other user is an eavesdropper. Perfect secrecy is achieved when the the transmitter and the legitimate receiver can communicate at some positive rate, while insuring that ...

Secrecy Capacity of a Class of Broadcast Channels with an Eavesdropper
EURASIP Journal on Wireless Communications and Networking, 2009 We study the security of communication between a single transmitter and many receivers in the presence of an eavesdropper for several special classes of broadcast channels. As the first model, we consider the degraded multireceiver wiretap channel where

Secrecy Rate Region Enhancement in Multiple Access Wiretap Channel
Journal of Telecommunications and Information Technology, 2022 It is commonly known that physical layer security is achieved with a trade-off in terms of the achievable rate. Hence, security constraints generate rate losses in wiretap channels.

Finite-blocklength bounds for wiretap channels [PDF]
2016 IEEE International Symposium on Information Theory (ISIT), 2016 This paper investigates the maximal secrecy rate over a wiretap channel subject to reliability and secrecy constraints at a given blocklength. New achievability and converse bounds are derived, which are shown to be tighter than existing bounds. The bounds also lead to the tightest second-order coding rate for discrete memoryless and Gaussian wiretap ...

On the Binary Input Gaussian Wiretap Channel with/without Output Quantization
Entropy, 2017 In this paper, we investigate the effect of output quantization on the secrecy capacity of the binary-input Gaussian wiretap channel. As a result, a closed-form expression with infinite summation terms of the secrecy capacity of the binary-input Gaussian
