Cryptanalysis and improvement of an encryption scheme that uses elliptic curves over finite fields
Kuwait Journal of Science, 2021 In this paper, we cryptanalyzed a recently proposed encryption scheme that uses elliptic curve over a finite field. The security of proposed scheme depends upon elliptic curve discrete logarithm problem.

No-go theorem for heralded exact one-way key distillation [PDF]
QuantumThe heralded exact one-way distillable secret key is equal to the largest expected rate at which perfect secret key bits can be probabilistically distilled from a bipartite state by means of local operations and one-way classical communication.

Secret Key Generation With Limited Interaction
IEEE Transactions on Information Theory, 2017 A basic two-terminal secret key generation model is considered, where the interactive communication rate between the terminals may be limited, and in particular may not be enough to achieve the maximum key rate. We first prove a multi-letter characterization of the key-communication rate region (where the number of auxiliary random variables depend on ...

Secret Distribution of Keys for Public-Key Systems [PDF]
, 1988 This paper proposes new public-key cryptosystems systems the security of which is based on the tamperfreeness of a device and the existence of secret key cryptosystems instead of the computational complexity of a trapdoor one-way function (RSA).

Asymmetry in Skipping Enhances Viability Against Control Input Noise
Advanced Robotics Research, EarlyView.Quadruped animals use asymmetric galloping gaits at high speeds, yet the functional role of this asymmetry remains unclear. This study shows that left–right asymmetry in touchdown angles enhances robustness to control noise. Using a simple two‐legged locomotion model and viability theory, it demonstrates that asymmetric skipping substantially enlarges ...

A Perspective on Interactive Theorem Provers in Physics
Advanced Science, EarlyView.Into an interactive theorem provers (ITPs), one can write mathematical definitions, theorems and proofs, and the correctness of those results is automatically checked. This perspective goes over the best usage of ITPs within physics and motivates the open‐source community run project PhysLean, the aim of which is to be a library for digitalized physics

Angewandte Chemie, EarlyView.Red‐emissive carbon dots (R‐CDs) exhibiting aggregation‐induced emission (AIE) and aggregation‐caused quenching (ACQ) effects are synthesized from citric acid and urea. They display weak blue fluorescence in water but strong red emission in DMF due to aggregation.

Using a secret key to foil an eavesdropper [PDF]
2010 48th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2010 This work addresses private communication with distributed systems in mind. We consider how to best use secret key resources and communication to transmit signals across a system so that an eavesdropper is least capable to act on the signals. One of the key assumptions is that the private signals are publicly available with a delay---in this case a ...
