HASBE access control model with Secure Key Distribution and Efficient Domain Hierarchy for cloud computing

Abstract

Cloud computing refers to the application and service that run on a distributed system using virtualized resources and access by common internet protocol and networking standard. Cloud computing virtualizes system by pooling and sharing resources. System and resources can be monitored from central infrastructure as needed. It requires high security because now day’s companies are placing more essential and huge amount of data on cloud. Hence traditional access control models are not sufficient for cloud computing applications. So encryption based on Attribute (“ABE”-“Attribute based encryption”) has been offered for access control of subcontracted data in cloud computing with complex access control policies. Traditional HASBE provides Flexibility, scalability and fine-grained access control but does not support hierarchical domain structure. In this paper, we had enhanced “Hierarchical attribute-set-based encryption” (“HASBE”) access control with a hierarchical assembly of users, with flexible domain Hierarchy structure and Secure key distribution with predefined policy

Enhancing multi‐tenancy security in the cloud computing using hybrid ECC‐based data encryption approach

“…The decryption of the message is done only by the person who carries the equivalent private keys [12]. Recently, asymmetric algorithms are well recognised like elliptic curve cryptography (ECC) compared to symmetric, such as the AES algorithm [13], data encryption standard (DES) algorithm [14], and blowfish algorithm [15]. The AES algorithm used a simple algebraic structure and, therefore, easily hacked by the attacker.…”

A cost-effective 2-tier security paradigm to safeguard cloud data with faster authentication

“…Authors proved that proposed scheme reduces the system complexity and improve the efficiency by maximizing the number of domain levels. Meanwhile, in Chennam and Lakshmi [12] proposed a ciphertext attribute-based encryption scheme which ensures a strong security policy for data sharing and protects the privacy of the cloud users with secure dynamic processing.…”
