Efficient Multi-Party Quantum Secret Sharing Schemes
, 2004 In this work, we generalize the quantum secret sharing scheme of Hillary, Bu\v{z}ek and Berthiaume[Phys. Rev. A59, 1829(1999)] into arbitrary multi-parties. Explicit expressions for the shared secret bit is given.

Nearly optimal robust secret sharing [PDF]
, 2016 : We prove that a known approach to improve Shamir's celebrated secret sharing scheme; i.e., adding an information-theoretic authentication tag to the secret, can make it robust for n parties against any collusion of size δn, for any constant δ ∈ (0; 1/2)

Secret Key Generation from Correlated Sources and Secure Link
, 2017 In this paper, we study the problem of secret key generation from both correlated sources and a secure channel. We obtain the optimal secret key rate in this problem and show that the optimal scheme is to conduct secret key generation and key ...

Hyper Secure Algorithm for Text [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2011 Classical encryption methods depend on two basic encryption method, namely MONO ALPHABET and POLY ALPHABET. In this research, we developed a hybrid encryption algorithm to overcome the weaknesses in both methods and employed the basic ...

Advanced Functional Materials, EarlyView.Inspired by natural silicified wood, a biomimetic mineralized chitin‐derived aerogel is constructed. It can withstand 81 000 times its own weight, and its backside temperature is 130.4°C after exposure to ∼1300°C butane flame for 600 s, exhibiting high‐strength, fire‐resistance, and super thermal‐insulation properties.

Le secret de Jean-Joseph Surin ou l’expérience de l’impensable damnation
Les Dossiers du GRIHL, 2009 The word mysticism means the opposite of religious "fact". It means the opposite of what is observable and positive, so that we could reduce mysticism to an occult tradition that we are able to discover and communicate.

Deterministic secure direct communication using GHZ states and swapping quantum entanglement [PDF]
, 2005 We present a deterministic secure direct communication scheme via entanglement swapping, where a set of ordered maximally entangled three-particle states (GHZ states), initially shared by three spatially separated parties, Alice, Bob and Charlie ...

Advanced Functional Materials, EarlyView.When hydrated zinc ions are deposited onto Cu substrates at practical current densities, the modified Cu enables simultaneously compact zinc growth and suppressed hydrogen evolution. This regulatory effect originates from the superior adsorption of the modified Cu interface, which enhances zincophilicity and the hydrogen desorption barrier, thereby ...
