Addressing leakage of re-encryption key in proxy re-encryption using trusted computing

, 2011
Proxy re-encryption is a cryptographic primitive enabling a proxy holding a re-encryption key to convert a ciphertext originally intended for Alice (delegator) into an encryption of the same message for Bob (delegatee).

Integrating Genetics With Epidemiological Measurements Identifies Burden QTLs of Inflammatory Bowel Disease across 20 Countries

Advanced Science, EarlyView.
The burden quantitative trait locus (bQTL) analysis integrates epidemiological data from GBD study with genotype of 2 621 978 SNPs from 2414 individuals in 1000 Genomes Project across 20 countries. rs7633471 shows the strongest effect that each increase in centi‐allele frequency of the allele C associated with 10.00 decrease of age‐standardized ...

Improved Proxy Re-encryption Scheme for Symmetric Key Cryptography [PDF]

, 2021
A proxy re-encryption scheme can be executed by a semi-trusted proxy, so that we can transform a ciphertext encrypted with a key to another ciphertext encrypted with different key without allowing the proxy to access the plaintext.

Synthetic Toll‐Like Receptors for Control of Innate Immunity With Far‐Red Light

Advanced Science, EarlyView.
Synthetic Toll‐like receptors (TLRs) are engineered by replacing their natural sensing regions with a far‐red‐light‐responsive module from a bacterial phytochrome. These synthetic receptors enable light‐controlled regulation of immune signaling in mammalian cells.

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.

Pre‐Regenerative Endothelial Cells Empowered by Antler Blood Exosomes Orchestrate Peripheral Nerve Repair

Advanced Science, EarlyView.
The pre‐regenerative vascular niche (PVN) is essential for nerve repair, yet its endothelial blueprint remains unclear. We identified angiogenic ECs (AECs) as the dominant pre‐regenerative subset and found that antler blood–derived exosomes (AB‐EXO) promote repair via IMP3.
