Impact of Realistic Propagation Conditions on Reciprocity-Based Secret-Key Capacity [PDF]

2020 IEEE 31st Annual International Symposium on Personal, Indoor and Mobile Radio Communications, 2020
Secret-key generation exploiting the channel reciprocity between two legitimate parties is an interesting alternative solution to cryptographic primitives for key distribution in wireless systems as it does not rely on an access infrastructure and provides information-theoretic security.

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.

On the Secret Key Capacity of Sibling Hidden Markov Models

IEEE Transactions on Information Forensics and Security, 2019
Traditional approaches to secret key establishment based on common randomness have been based on certain restrictive assumptions, such as considering the available common randomness to consist of independent and identically distributed (i.i.d) repetitions of correlated random variables. Unfortunately, the i.i.d assumption does not generally reflect the

Secret Key Agreement for SISO Visible Light Communication Systems

Photonics
This paper studies the use of secret key agreement for single-input single-output (SISO) visible light communication (VLC) systems. Specifically, we put forward a scheme for secret key generation and analyze the secret key rate in SISO VLC systems. First,

A Two-Layer Secure Quantization Algorithm for Secret Key Generation With Correlated Eavesdropping Channel

IEEE Access, 2019
When the eavesdropping channel has a certain correlation with the legitimate channel, the physical layer key is susceptible to eavesdroppers. To ensure the security of the secret key, we propose a two-layer secure (TLS) quantization algorithm in this ...
