Quantum public-key encryption protocol based on single-photon

open access: yesTongxin xuebao, 2014
A quantum public-key encryption protocol based on single-photon was provided.Pseudo random sequence mapping to private keys to implement corresponding quantum operations and then obtaining quantum public-key to encode the plaintext was used.Employ the ...

Provably secure and efficient escrowable public key encryption schemes

open access: yesTongxin xuebao, 2014
In an escrowable public key encryption (E-PKE) scheme, there are two keys associated with one public key. It can reduce the total number of certificates in the public key infrastructure (PKI) to a large extent, thus degrade the com-plexity of certificate

A Physiological Microfluidic Blood–Brain‐Barrier Model for In Vitro Study of Nanoparticle Trafficking and Accumulation

open access: yesAdvanced Healthcare Materials, EarlyView.
A human microfluidic blood‐brain barrier (mBBB) model enables spatially resolved comparison of nanoparticle trafficking. Extracellular vesicles (EVs), liposomes, and nanoplastics exhibit distinct transport and disruption behaviors, revealing that membrane composition and uptake pathways govern BBB interaction.

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

open access: yesAdvanced Materials, EarlyView.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

Self‐Powered Flexible Triboelectric‐Gated Ion‐Gel Transistor for Neuromorphic Tactile Sensing and Human Activity Recognition

open access: yesAdvanced Materials, EarlyView.
A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.

Novel construction of forward-secure public-key encryption in the standard model

open access: yesTongxin xuebao, 2014
All existing provably secure forward-secure public-key encryption schemes in the literature were only proven to be chosen-plaintext secure. A novel forward-secure public-key encryption scheme without random oracles was pro-posed.
