Certificateless public key cryptography
, 2011 A criptografia de chave pública sem certificado (certificateless) é uma alternativa ao modelo convencional de criptografia assimétrica, pois a autenticação da chave pública ocorre implicitamente durante a execução dos protocolos, sem a necessidade de ...

Gapless Superconductivity From Extremely Dilute Magnetic Disorder in 2H‐NbSe2‐xSx
Advanced Materials, EarlyView.We demonstrate that 2H‐NbSe2‐xSx hosts gapless superconductivity at unexpectedly low magnetic impurity concentrations. Combining STM, Bogoliubovde Gennes simulations, DFT, and quasiparticle interference, we comprehensively study the development of gapless behavior and show that SeS substitution reshapes the band structure, enhances nesting, and drives ...

Security of signed ELGamal encryption
, 2005 Assuming a cryptographically strong cyclic group G of prime order q and a random hash function H, we show that ElGamal encryption with an added Schnorr signature is secure against the adaptive chosen ciphertext attack, in which an attacker can freely use

Survey on Asymmetric Key Cryptography Algorithms
, 2014 Asymmetric key encryption is also called public key encryption. It uses two keys known as a public and a private key. Data encrypted with one key can be decrypted only with the other key. This paper discusses some public key algorithms and its advantages

Advanced 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.
