Humans identify negative (but not positive) arousal in silver fox vocalizations: Implications for the adaptive value of interspecific eavesdropping
eavesdropping emotional arousal emotional valence
2017/8/28
The ability to identify emotional arousal in heterospecific vocalizations may facilitate behaviors that increase survival opportunities. Crucially, this ability may orient inter-species interactions, ...
Honey Chatting: A novel instant messaging system robust to eavesdropping over communication
Honey Encryption Language model
2017/2/20
There have been many efforts to strengthen security of Instant Messaging (IM) system. One of the typical technologies is the conventional message encryption using a secret or private key. However, the...
Eavesdropping or Disrupting a Communication --- On the Weakness of Quantum Communications
foundations quantum cryptography
2014/3/11
What is the behavior of an adversary to launch attacks against a communication? The good choice is to eavesdrop the communication such that the communicators can not detect the eavesdropping. The gene...

2010/11/8
The stated goal of quantum key distribution (QKD) is to grow a secret key securely between two parties with a minimum of additional assumptions. The number of assumptions has been continuously reduced...
Securing Dynamic Distributed Storage Systems against Eavesdropping and Adversarial Attacks
Eavesdropping Adversarial Attacks
2010/12/6
We address the problem of securing distributed storage systems against eavesdropping and adversarial attacks. An important aspect of these systems is node failures over time, ecessitating, thus, a rep...
We consider the problem of communicating information over a network secretly and reliably in the presence of a hidden adversary who can eavesdrop and inject malicious errors. We provide polynomial-tim...

On 16 December 2005, the New York Times reported that the President had authorized the National Security Agency (NSA) to spy on Americans, inside the United States, without first obtaining a warrant f...
Eavesdropping of two-way coherent-state quantum cryptography via Gaussian quantum cloning machines

2010/4/9
We consider one of the quantum key distribution protocols recently introduced in Ref. [Pirandola et al., Nature Physics 4, 726 (2008)]. This protocol consists in a two-way quantum communication betwee...
Quantum Resonance near Optimal Eavesdropping in Quantum Cryptography
Quantum Optimal Eavesdropping Quantum Cryptography
2010/4/7
We find a resonance behavior in the disturbance when an eavesdropper chooses a near-optimal strategy intentionally or unintentionally when the usual Bennett-Brassard cryptographic scheme is performed ...

2010/9/26
Music and speech both feature structured melodic patterns, yet these
patterns are rarely compared using empirical methods. One reason for this has been a
lack of tools which allow quantitative compa...

The composer Leo Janáek (1854-1928) has been noted for his interest in
speech melodies. Little discussion has focused however on the field methods that he used
in gathering them,...
