Storage

Storage

A schema is a mental framework that helps individuals organize and interpret information. Schemata, formed from previous experiences, influence how we process new information: how we encode it, the inferences we make, and how we retrieve it. For instance, a schema for what a typical classroom looks like might include desks, a teacher's desk, a whiteboard, and students in such an environment. This expectation helps us quickly understand and navigate new classrooms without needing to analyze...

Role-Based Identity

Role-Based Identity

Role-based identities are central to understanding how individuals navigate social environments by adopting distinct self-conceptions aligned with various societal roles. These identities are not fixed traits but are constructed through personal actions and the social feedback individuals receive in context-specific interactions. Each social role, such as student, teacher, or friend, carries a set of expectations and norms that influence how people think, feel, and behave within that...

Protection of Alcohols

Protection of Alcohols

This lesson delves into the concept of protection and deprotection of a functional group fundamental to synthetic organic chemistry. These phenomena are explained in the context of aliphatic and aromatic alcohols.
Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...

Protecting Groups for Aldehydes and Ketones: Introduction

Protecting Groups for Aldehydes and Ketones: Introduction

Protecting groups are compounds that can bind to a specific functional group in the presence of other functional groups to protect them from undesired chemical reactions. These compounds can selectively bind to particular functional groups and advance chemoselective reactions in polyfunctional systems (Figure 1). After the functional group has served its purpose, it is removed by reacting it with specific compounds.

Retrieval

Retrieval

Retrieval is the process of getting information out of memory storage and back into conscious awareness. This ability is essential for daily tasks like brushing hair and teeth, driving to work, and performing job duties. Retrieval occurs in three ways: recall, recognition, and relearning.
Recall involves accessing information without cues, such as during an essay test, where individuals must retrieve facts and concepts from memory unaided. Another example is remembering the name of a colleague...

Area of Science:

Cryptography and Information Security
Cloud Computing Security

Background:

Cipher-policy attribute-based encryption (CP-ABE) addresses access control.
Keyword-based searchable encryption facilitates quick file retrieval in cloud storage.

Purpose of the Study:

To design an efficiently searchable and attribute-based encryption scheme for multi-user cloud storage.
To incorporate attribute revocation and granting functionalities.
To achieve simultaneous multi-attribute revocation and granting.

Main Methods:

Proposed an efficiently multi-user searchable attribute-based encryption scheme.
Delegated attribute revocation and granting processes to a proxy server.
Achieved keyword search functionality within the attribute-based encryption framework.

Main Results:

The scheme supports efficient multi-attribute revocation and granting simultaneously.
Security is reduced to the bilinear Diffie-Hellman (BDH) assumption.
Proven secure under indistinguishability against selective ciphertext-policy and chosen plaintext attack (IND-sCP-CPA) and semantic security against chosen keyword attack (IND-CKA).

Conclusions:

The proposed scheme effectively integrates searchable capabilities with attribute-based encryption for secure cloud storage.
It provides efficient and secure access control with dynamic attribute management.
The scheme demonstrates robust security guarantees against sophisticated attacks.
