Hierarchical Identity-Based Matchmaking Encryption [PDF]
IEICE Transactions on Fundamentals of Electronics, Communications and Computer SciencesIdentity-based matchmaking encryption (IB-ME) is an advanced encryption scheme that allows both the sender and the receiver to specify their respective identities.

Cryptography, 2018 An Identity-based encryption (IBE) simplifies key management by taking users’ identities as public keys. However, how to dynamically revoke users in an IBE scheme is not a trivial problem.

Proxy Re-encryption Systems for Identity-Based Encryption [PDF]
, 2007 A proxy re-encryption system allows the proxy to transform ciphertexts encrypted under Alice's public key into the different ciphertexts that can be decrypted by Bob's secret key. In this paper, we propose new proxy re-encryption systems; one for the transformation from ciphertexts encrypted under a traditional PKI-based public key into the ciphertexts

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 ...

Efficient Identity-based Encryption Scheme over Ideal Lattice [PDF]
Jisuanji gongcheng, 2016 Recently,Identity-based Encryption(IBE) scheme based on lattices becomes one of the focuses of cryptographic research.But the IBE scheme based on standard lattice have large key size and high ciphertext expansion rate.So based on ideal lattices,this ...

Security of signed ELGamal encryption [PDF]
, 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

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.

Multi-identity Fully Homomorphic Encryption Scheme Supporting Threshold Decryption
工程科学与技术, 2019 In order to solve the problem that traditional identity-based fully homomorphic encryption schemes can only perform homomorphic operations and access control on ciphertexts under the same identity, a multi-identity fully homomorphic encryption scheme was

Revocable Hierarchical Identity-Based Broadcast Encryption
Tsinghua Science and Technology, 2018 Hierarchical Identity-Based Broadcast Encryption (HIBBE) organizes users into a tree-like structure, and it allows users to delegate their decryption ability to subordinates and enable encryption to any subset of users while only intended users can ...
