Shared and Searchable Encrypted Data for Untrusted Servers [PDF]

, 2008
Current security mechanisms pose a risk for organisations that outsource their data management to untrusted servers. Encrypting and decrypting sensitive data at the client side is the normal approach in this situation but has high communication and ...

Multi-authority attribute-based encryption access control model for cloud storage

Tongxin xuebao, 2015
The existing attribute-based encryption access control studies are mostly based on single authority,and this scheme is apt to be under attack to cause exposure of secret keys.Thus,a multi-authority access control model PRM-CSAC is proposed.Based on CP ...

Provably Secure Ciphertext-Policy Attribute-Based Encryption from Identity-Based Encryption [PDF]

Journal of Universal Computer Science, 2019
Ciphertext-policy attribute-based encryption (CP-ABE) is an access control mechanism where a data provider encrypts a secret message and then sends the ciphertext to the receivers according to the access policy which she/he decides.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Toward Dynamic Attribute-Based Signcryption (Poster) [PDF]

, 2011
This paper presents an ongoing work toward the proposal of the new concept of the attribute-based cryptosystem. In SCN2010, Gagné, Narayan, and Safavi-Naini proposed attribute-based signcryption (ABSC) with threshold structure.

Attribute-Based Encryption for Range Attributes

IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2016
Attribute-Based Encryption ABE is an advanced form of public-key encryption where access control mechanisms based on attributes and policies are possible. In conventional ABE, attributes are specified as strings. However, there are certain applications where it is useful to specify attributes as numerical values and consider a predicate that determines

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

FEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Blind Brother: Attribute-Based Selective Video Encryption

The emergence of video streams as a primary medium for communication and the demand for high-quality video sharing over the internet have given rise to several security and privacy issues, such as unauthorized access and data breaches.

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

PT-CPABKS – Secure Multi-User Keyword Search in Cloud Using Policy-Tiered CP-ABE with Optimized Indexing

Cybernetics and Information Technologies
Cloud computing faces several challenges in balancing data confidentiality with efficient retrieval and fine-grained access control. Conventional searchable encryption models enable keyword search but lack fine-grained access control, whereas traditional
