Efficient selective identity-based encryption without random oracles [PDF]
, 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

Identity-Based Matrix (Level) Fully Homomorphic Encryption Scheme
Jisuanji kexue yu tansuo, 2020 With the development of quantum theory, traditional encryption algorithms are facing enormous challenges. Once quantum computers are available, existing encryption systems will no longer be secure.

Delegate and Verify the Update Keys of Revocable Identity-Based Encryption
IEEE Access, 2023 Revocable identity-based encryption (RIBE) is an extension of identity-based encryption (IBE) and it supports efficient revocation of private keys. In the past, many efficient RIBE schemes have been proposed, but research on efficiently delegating the ...

Identity-Based Encryption in DDH Hard Groups
, 2022 International audienceThe concept of Identity-Based Encryption was first introduced by Shamir (CRYPTO 1984) but were not realised until much later by Sakai, Ohgishi and Kasahara (SCIS 2000), Boneh and Franklin (CRYPTO 2001) and Cocks (IMACC 2001).

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Multi-server conjunctive keyword searchable encryption scheme based on BDH problem
Dianxin kexue, 2020 Searchable encryption is a cryptographic primitive that supports users to search for keywords on ciphertext.In view of the low efficiency of traditional single-server searchable encryption schemes,it was based on the advantages of identity management in ...

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...
