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 ...

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 ...

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

Natural Killer Cells in Paediatric Soft Tissue Sarcomas: A Systematic Review
Pediatric Blood &Cancer, EarlyView.ABSTRACT Paediatric soft tissue sarcomas (pSTS) are a rare and heterogeneous group of malignant tumours arising in tissues of mesenchymal origin. The role of natural killer (NK) cells in pSTS remains poorly understood, with evidence fragmented across small preclinical studies and early‐phase clinical trials.

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

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

Identity-Based Encryption for Sensor Networks [PDF]
Fifth Annual IEEE International Conference on Pervasive Computing and Communications Workshops (PerComW'07), 2007 In spite of several years of intense research, the area of security and cryptography in wireless sensor networks (WSNs) still has a number of open problems. On the other hand, the advent of identity-based encryption (IBE) has enabled a wide range of new cryptographic solutions. In this work, we argue that IBE is ideal for WSNs and vice versa.
