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.

Identity Based Group Signatures from Hierarchical Identity-Based Encryption [PDF]
, 2009 A number of previous papers explored the notion of identity-based group signature. We present a generic construction of identity-based group signatures.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Efficient Equality Test on Identity-Based Ciphertexts Supporting Flexible Authorization
Entropy, 2023 In the cloud, uploading encrypted data is the most effective way to ensure that the data are not leaked. However, data access control is still an open problem in cloud storage systems.

Efficient selective identity-based encryption without random oracles
, 2010 We construct two efficient Identity-Based Encryption (IBE) systems that admit selective-identity security reductions without random oracles in groups equipped with a bilinear map. Selective-identity secure IBE is a slightly weaker security model than the

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

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

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
