The Secret Key Capacity of a Class of Noisy Channels with Correlated Sources [PDF]
Entropy, 2019 This paper investigates the problem of secret key generation over a wiretap channel when the terminals observe correlated sources. These sources are independent of the main channel and the users overhear them before the transmission takes place.

Noncoherent Capacity of Secret-Key Agreement With Public Discussion [PDF]
IEEE Transactions on Information Forensics and Security, 2011 We study the noncoherent capacity of secret-key agreement with public discussion over independent identically distributed (i.i.d.) Rayleigh fading wireless channels, where neither the sender nor the receivers have access to instantaneous channel state information (CSI). We present two results.

Wiretap Secret Key Capacity of Tree-PIN [PDF]
2019 IEEE International Symposium on Information Theory (ISIT), 2019 We consider the problem of multiterminal secret key agreement (SKA) in wiretapped source model where terminals have access to samples of correlated random variables from a publicly known joint probability distribution. The adversary has access to a side information variable, that is correlated with terminals' variables.

Secret key agreement: General capacity and second-order asymptotics [PDF]
2014 IEEE International Symposium on Information Theory, 2014 We revisit the problem of secret key agreement using interactive public communication for two parties and propose a new secret key agreement protocol. The protocol attains the secret key capacity for general observations and attains the second-order asymptotic term in the maximum length of a secret key for independent and identically distributed ...

The Capacity Region of the Source-Type Model for Secret Key and Private Key Generation [PDF]
IEEE Transactions on Information Theory, 2014 The problem of simultaneously generating a secret key (SK) and private key (PK) pair among three terminals via public discussion is investigated, in which each terminal observes a component of correlated sources. All three terminals are required to generate a common secret key concealed from an eavesdropper that has access to public discussion, while ...

IEEE AccessSteganography hides a secret message inside another medium (cover-image) while maintaining imperceptibility and/or robustness/embedding capacity, making it a suitable candidate for keeping information safe and hiding the existence of data itself inside ...

The Sender-Excited Secret Key Agreement Model: Capacity, Reliability, and Secrecy Exponents [PDF]
IEEE Transactions on Information Theory, 2015 We consider the secret key generation problem when sources are randomly excited by the sender and there is a noiseless public discussion channel. Our setting is thus similar to recent works on channels with action-dependent states where the channel state may be influenced by some of the parties involved.

Capacity of a shared secret key [PDF]
2010 IEEE International Symposium on Information Theory, 2010 Shannon theoretic shared secret key generation by multiple terminals is considered for a source model in which the components of a discrete memoryless multiple source and a noiseless public channel of unlimited capacity are available for accomplishing this goal.

Entropy, 2022 In this paper, we propose an improved physical layer key generation scheme that can maximize the secret key capacity by deploying intelligent reflecting surface (IRS) near the legitimate user aiming at improving its signal-to-noise ratio (SNR).

The secret key~private key capacity region for three terminals [PDF]
Proceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005 We consider a model for secrecy generation, with three terminals, by means of public interterminal communication, and examine the problem of characterizing all the rates at which all three terminals can generate a ``secret key,'' and -- simultaneously -- two designated terminals can generate a ``private key'' which is effectively concealed from the ...
