Role-Based Identity01:21

Role-Based Identity

240
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...

Distribution Reliability and Automation

542
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...

Masking and Demasking Agents01:19

Masking and Demasking Agents

3.7K
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...

Integrated Healthcare System

2.5K
An integrated healthcare system (IHS) is a set of organizations that provides for or arranges to provide coordinated and continuous service to a defined population. The IHS takes responsibility for that particular population's health status and outcome, both clinically and fiscally. An integrated healthcare system is a well-organized, well-coordinated, and collaborative network. The integrated delivery system is a network that connects different healthcare providers to deliver organized,...

Quality Assurance01:19

Quality Assurance

3.7K
Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...

Area of Science:

  • Computer Science
  • Information Security
  • Distributed Systems

Background:

  • The proliferation of big data and the Internet of Things (IoT) has led to massive increases in networked devices and data volumes.
  • Fog computing extends cloud capabilities to the network edge, addressing data transmission and storage bottlenecks.
  • However, fog-cloud environments introduce significant security and privacy concerns, necessitating robust access control mechanisms.

Purpose of the Study:

  • To propose a novel verifiable outsourced multi-authority access control scheme (VO-MAACS) for fog-cloud computing environments.
  • To enhance data security and privacy by implementing efficient access control and revocation mechanisms.
  • To ensure computational efficiency by outsourcing encryption and decryption processes to fog devices.

Main Methods:

  • Implementation of a Ciphertext-Policy Attribute-Based Encryption (CP-ABE) scheme tailored for multi-authority settings.
  • Development of a verification method to validate outsourced computation results from fog devices.
  • Design of an efficient revocation strategy for users and attributes within the scheme.

Main Results:

  • The proposed VO-MAACS scheme demonstrates strong security guarantees against unauthorized access.
  • Outsourced computations are verifiable, ensuring the integrity of the access control process.
  • Efficient user and attribute revocation is achieved, addressing a critical challenge in dynamic environments.
  • Simulation results confirm the scheme's high efficiency in terms of computation and communication overhead.

Conclusions:

  • The VO-MAACS scheme effectively addresses the security and privacy challenges in fog-cloud computing.
  • It provides a practical solution for data access control in IoT environments with multiple authorities.
  • The scheme offers a balance between security, efficiency, and verifiability, making it suitable for real-world deployment.
