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...

Short-distance Transport of Resources

Short-distance Transport of Resources

Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

Distributed Loads

Distributed Loads

Distributed loads are a common type of load that engineers and scientists encounter in various practical situations. Distributed loads often refer to a type of load spread over a surface or a structure and can be modeled as continuous force per unit area.
For example, consider a bookshelf filled with books stacked vertically adjacent to each other. The weight of the books is evenly distributed over the length of the shelf. As a result, the pressure at different locations on the surface of the...

Ethical Standards I

Ethical Standards I

The American Nurses Association (ANA) created and implemented the first nationally accepted Code of Ethics for Nurses with Interpretive Statements. The Code of Ethics is a living document regularly updated by the ANA and establishes an ethical standard that is non-negotiable for nurses in all roles and settings.
The Code of Ethics provisions outline the nurse's duty to the patient, the healthcare team, the profession, and society. The Code's fundamental principles include advocacy,...

Maximum Size of Aggregate

Maximum Size of Aggregate

The maximum size of aggregate is defined as the aperture of the sieve retaining 15 percent or more of the particles present in the aggregate sample. The aggregate's maximum size impacts the concrete's water requirement, workability, and strength. Larger aggregates reduce the surface area needing cement paste coverage, which can lower water needs, thereby allowing a decrease in the water-to-cement ratio when the desired workability and richness of the mix are to be maintained, which can...

Distribution Reliability and Automation

Distribution Reliability and Automation

Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

Area of Science:

Cryptography and Network Security
Mobile Computing
Cloud Computing

Background:

Mobile Cloud Computing (MCC) integrates mobile devices with cloud computing for enhanced data storage, computation, and sharing.
Attribute-Based Encryption (ABE) offers fine-grained access control but is computationally intensive for mobile devices.
Existing ABE schemes are unsuitable for MCC due to expensive pairing operations, hindering MCC adoption.

Purpose of the Study:

To propose a secure and lightweight fine-grained data sharing scheme (SLFG-DSS) tailored for mobile cloud computing environments.
To address the computational limitations of mobile devices in MCC by outsourcing intensive operations to cloud servers.
To enhance data security and access control in MCC scenarios.

Main Methods:

Development of a novel secure and lightweight fine-grained data sharing scheme (SLFG-DSS).
Outsourcing of time-consuming cryptographic operations from mobile devices to cloud servers.
Implementation of verifiable outsourced decryption and resistance to decryption key exposure.
Achieving Chosen-Ciphertext Attack (CCA) security.

Main Results:

The proposed SLFG-DSS scheme supports verifiable outsourced decryption, allowing mobile users to verify ciphertext validity.
The scheme effectively resists decryption key exposure, securing user data during outsourced decryption.
The scheme achieves a high level of security (CCA security), suitable for sensitive applications.
Security proofs and performance analysis confirm the scheme's effectiveness and suitability for MCC.

Conclusions:

The developed SLFG-DSS provides a secure, efficient, and lightweight solution for fine-grained data sharing in MCC.
Outsourcing decryption computations significantly alleviates the burden on resource-constrained mobile devices.
The scheme's enhanced security features make it applicable to MCC scenarios with stringent security requirements.
