A Survey on Access Control in Cloud Computing

A Survey on Blockchain Envisioned Attribute Based Access Control for Internet of Things: Overview, Comparative Analysis, and Open Research Challenges

“…𝑊 𝑆𝑁𝐷 𝑎𝑣𝑔 = 𝑦 ∑ 𝑏=1 𝛾 𝑏 𝑁𝐷 𝑎𝑏 (10) Step Six (Ranking): ''The scores obtained are based on the 𝑊 𝑆𝑃 𝐷 𝑎𝑣𝑔 & 𝑊 𝑆𝑁𝐷 𝑎𝑣𝑔 , which are calculated using the rated methods specified in Eqs. (11) and (12), respectively''.…”

“…In Eqs. (11) and ( 12) are utilized to compute the 𝑊 𝑆𝑁𝐷 𝑎𝑣𝑔 and 𝑁(𝑊 𝑆𝑁𝐷 𝑎𝑣𝑔 ). After performing defuzzification on the evaluation score, the alternatives were ranked using Eq.…”

“…This model offers a fundamental level of safety [10]. Users' permissions are delegated to them in accordance with their roles within a system using the (RBAC) model [11]. Access decisions are made based on the relationships between roles and permissions and between users and roles.…”

“…This model offers a fundamental level of safety [10]. Users' permissions are delegated to them in accordance with their roles within a system using the (RBAC) model [11]. Access control models, including RBAC, tend to have lower management efficiency when it comes to the complex requirements of IoT systems.…”

“…This highlights the need for alternative access control models better suited to IoT environments' dynamic and expansive nature. Implementing detailed access control scenarios in these models is challenging while simultaneously applying the principle of least privilege [11]. Nevertheless, the IoT requires an access control model that is dynamic, fine-grained and goes beyond user-centricity.…”
