Public-Key Authenticated Encryption with Keyword Search Made Easy [PDF]

Public-key searchable encryption allows keyword-associated tokens to be used to test if a ciphertext contains specific keywords. Due to the low entropies of keywords, the token holder can create ciphertexts from candidate keywords and test them using

Public Trace-and-Revoke Proxy Re-encryption

, 2022
Proxy re-encryption (PRE), as a promising cryptographic primitive for secure data sharing in cloud, has been widely studied for decades. PRE allows the proxies to use the re-encryption keys to convert ciphertexts computed under the delegator’s public key

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Public key searchable encryption scheme based on blockchain

Tongxin xuebao, 2020
Aiming at the trapdoor security problem of the public key encryption scheme,a random number constructing trapdoor and index was introduced to defend against keyword guessing attacks from the server and avoid data leakage caused by server curious behavior.

An Efficient RSA Public Key Encryption Scheme

, 2008
In this paper, we propose an efficient RSA public key encryption scheme, which is an improved version of original RSA scheme. The proposed RSA encryption scheme is based on linear group over the ring of integer mod a composite modulus n which is the ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Cybersecurity-Enhanced Encrypted Control System Using Keyed-Homomorphic Public Key Encryption

IEEE Access, 2023
Encrypted control systems are secure control methods that use the cryptographic properties of a specific homomorphic encryption scheme. This study proposes a cyberattack-detectable encrypted control system and validates its effectiveness using a ...

Ubiquitination of secretory granules promotes their crinophagic degradation in Drosophila

FEBS Letters, EarlyView.
Ubiquitination of secretory granules in Drosophila larval salivary glands is a critical molecular trigger for crinophagy, the lysosomal degradation of unreleased, or low‐quality granules. The E3 ubiquitin ligase Cnot4 is recruited to the surface of secretory granules to induce crinophagy.

Partially coherent optical chip enables physical-layer public-key encryption

Opto-Electronic Advances
Public-key encryption is essential for secure communications, eliminating the need for pre-shared keys. However, traditional schemes such as RSA (Rivest-Shamir-Adleman) and elliptic curve cryptography rely on computational complexity, making them ...

Public-Key Encryption With Keyword Search via Obfuscation

IEEE Access, 2019
Public-key encryption with keyword search (PEKS) enables users to search on encrypted data, which is applicable to the scenario of sharing data in the cloud storage. In this paper, we focus on how to construct a PEKS scheme via obfuscation.
