Attribute-Based Encryption for Access of Secured Data in Cloud Storage

Cloud security is the most critical task while considering its working environment, i.e. outsourced, distributed and utility based. In such cases making the users data confidential, increases the trust over the system. Also the security procedure does not make the availability affected in any ways. The users of these kind of systems is always retained the services and securities preliminaries with respect to the data itself. As the cloud user can access its data frequently and if here some encryption is used which requires decryption and the repetitive process continues to increase the overheads. It requires some mechanism in which encryption is performed and if the user requires to perform some operations on secure file without decrypting it can be fulfilled. Thus homomorphic encryption lets the user facilitates about the performing operations on encrypted data which reduces the complexity of confidentiality operations. Also to prevent Cloud Servers from being able to learn both the data file contents and user access privilege information used to generate key along with the fastest access of secured data by using Attribute-based encryption (ABE).

A Survey Report on Attribute Based Encryption Methodologies to Secure Cloud Storage

Due to reliability, there are millions of the uses of the cloud storages. So clouds are widely developing field for various purposes. Many cloud hosts are providing services to different clients for their data. Due to disaster management cloud can be used as trustworthy storage mechanism. For such cloud storages encryption is done many a ways for securing data. The attribute based encryption is the method to encrypt the contents. This paper discusses the attribute based encryption method for the cloud storages. The method is also used to hide identity of the user that means the anonymous authentication can be implemented only by use of attributes.

Attribute based Access Control Scheme in Cloud Storage System

International Journal of Engineering & Technology, 2018

Cloud Computing is an emerging technology now a days , where cloud is most preferable when there is data backup, storage and data distribution service with low cost. But cloud is semi honest in nature due to not reveled storage and security structure thus while storing and sharing cloud data , its suppose to honest and secured. When data owners outsource their data in secured manner system should assure the security, data integrity and confidentiality. Here we noticed secure access controlling is the prime objective for s ensitive data management.in this regards we have been used ABE (Attribute based encryption) for the above objective. This paper concentrates on secure storage and sharing system.

Technology a Survey on Attribute Based Encryption Techniques in Cloud Computing

2015

Cloud computing is an emerging computing paradigm, enabling users to store their data remotely in a server and to provide services on-demand. In cloud computing, cloud users and cloud service providers are almost clear from different trust domains. The critical issues for remote data storage are data security and privacy. A secure user enforced the data access control and that mechanism must be provided before the cloud users have liberty to outsource delicate data to cloud for storage. With the emergence of sharing personal data on cloud servers, it is essential to acquire an efficient encryption system with a fine-grained access control to encrypt outsourced data. Attribute-Based Encryption is a public key based encryption that enables access control over encrypted data using access policies and ascribed attributes. In this paper, we are going to analyze various schemes for encryption and possible solutions for their limitations that consist of Attribute Based Encryption (ABE), CP...

IJERT-A Survey on Attribute-Based Encryption Technique for Scalable Data Sharing in Cloud Storage

Cloud storage enables networked online storage. Key management and key sharing plays the main role in the data sharing concept of cloud computing. While cloud computing brings new and challenging security threats to the outsourced data. Hence data owner does not have any control to ensure data security in host data centers. In this paper, Cipher text policy attribute-based encryption (CP-ABE) is introduced with Key aggregate cryptosystem a promising cryptographic solution to this issue. It enables data owners to define their own access policies over user attributes and enforce the policies on the data to be distributed and Attribute policies, Cipher text policies are being aggregated. This effectively eliminates the need to rely on the data storage server for preventing unauthorized data access and integrity. Adding User revocation model enables removing access to suspicious users and Intrusion detection system to alert the owner during defined attacks noticed.

A Review on Attribute Based Encryption Techniques of Access Control in Cloud Computing

International Journal of Distributed and Cloud Computing, 2018

Cloud computing has emerged as a marked change in the field of Information Technology. Services like "on-demand" and "pay-as-you-go" has caused the migration of government as well as industries IT infrastructures to cloud. As data and business logic is stored at remote cloud server, the security concerns related to cloud environment is different from conventional computing. In cloud computing, security of data is managed by CSPs and the data owner has no control over the security policy of his own data. The security and privacy are two significant factors that restrain the user from switching to untrusted cloud environment. Though switching to cloud cut IT costs enormously but secure data sharing always remain concern for data owners. Thus, these two areas need more focus for making secure data sharing in cloud computing environment. In this paper we have reviewed and compared various schemes for attribute based encryption in respect of cloud computing.

Attribute-Based Encryption Approach for Storage, Sharing and Retrieval of Encrypted Data in the Cloud

IEEE Access, 2020

One of the most cost-effective services in cloud computing is storage, used by businesses and individuals to outsource their massive data to untrusted servers. Efforts have studied problems around this application scenario in different fronts: efficiency, flexibility, reliability, and security. In this paper we address the security concerns of cloud storage under the scenario where users encrypt-then-outsource data, share their outsourced data with other users, and the service provider can be queried for searching and retrieval of encrypted data. As main distinctive, we propose a security approach for storage, sharing and retrieval of encrypted data in the cloud fully constructed on the basis of attribute-based encryption (ABE) thus enabling access control mechanisms over both the encrypted data and also for the information retrieval task through search access control. Compared to related works, our approach considers efficient encryption at three different levels: i) bulk encryption of data outsourced to the cloud, ii) keys management for access control over encrypted data by means of digital envelopes from attribute based encryption, and iii) novel construction for attribute based searchable encryption (ABSE). Our underlying ABE algorithms are carefully selected from the body of knowledge and novel constructions for ABSE are provided over the asymmetric setting (Type-III pairings) to support security levels of 128-bits or greater. Experimental results on benchmark data sets demonstrate the viability of our approach for practical realizations using Barreto-Naehrig curves.

A SURVEY ON ATTRIBUTE BASED ENCRYPTION TECHNIQUES IN CLOUD COMPUTING

ATTRIBUTE BASED DECENTRALIZED ACCESS CONTROL ON CLOUD STORAGE

Cloud computing has emerged as one of the most influential paradigms in the IT industry in recent years. Since this new computing technology requires users to entrust their valuable data to cloud providers, there have been increasing security and privacy concerns on outsourced data. Now-a-days as cloud is most widely used in mostly all fields so there is need of keeping data more secure & confidential which is outsourced on the cloud. As the cloud system is decentralized and distributed, any unauthorized user can access this data so to avoid this we need secure access control. In this system the access control is attribute based and ciphertext is used which is better scheme. This system provides hierarchical control structure to reduce burden of central authority. Computation cost of encryption and decryption is less and the size of ciphertext generated is constant. This proposed scheme is efficient, finegrained and scalable and also increases performance of the system.
