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).

Control Data on Cloud using Attribute- Based Encryption Technique

Cloud computing is revolutionary computing paradigm which enables flexible on-demand and low-cost usage of computing resources. But this Advantages contain different security problem such as. Badly configured server can lead to unauthorized access. Ciphertext–policy attribute based encryption(CP-ABE)is a promising cryptographic primitive for fine-grained access control of shared data. A user is able to decrypt a ciphertext if and only if his attributes satisfy the ciphertext access structure. In this paper we use A secure server plus application. this application provides a protected foundation for hosting your Web applications, and Web server configuration which plays a critical role in your Web application's security. Badly configured server can lead to unauthorized access. This system provides bidirectional encryption of communications between a client and server, which protects against eavesdropping and tampering with and/or forging the contents of the communication. As compared to existing schemes, our proposed scheme provide security for website account and sensitive information.

A Comprehensive Review of Access Control Mechanism Based on Attribute Based Encryption Scheme for Cloud Computing

International Journal of Advanced Pervasive and Ubiquitous Computing, 2019

Cloud computing is the most prevailing paradigm, which provides computing resources and services over the Internet. Due to immense development in services provided by cloud computing, the trend to share large-scale and confidential data on cloud has been increased. Though cloud computing provides many benefits, ensuring security of the data stored in cloud is the biggest challenge. The security concern about the data becomes main barrier for adoption of cloud. One of the important security aspects is fine grained access control mechanism. The most widely used and efficient access control scheme for cloud computing is Attribute Based Encryption (ABE). The Attribute Based Encryption (ABE) scheme provides a new technique for embedding access policies cryptographically into encryption process. The article presents an overview of various existing attribute-based encryption schemes and traditional access control models. Also, the comparison of existing ABE schemes for cloud computing, on ...

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.

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...

IT Engineering, PCET’s NMIET Pune, Maharashtra, India ---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Fine grained access management could be a demand for knowledge stored in untrusted servers like clouds. Due to the massive volume of data, redistributed key management schemes square measure most popular over centralized ones. Usually coding and cryptography square measure quite expensive and not sensible once user’s access knowledge from resource constrained devices. We tend to propose a redistributed attribute primarily based encryption (ABE) method with quick coding, outsourced cryptography and user revocation. Our scheme is incredibly specific to the context of mobile cloud because the storage of encrypted knowledge and therefore the partial decryption of cipher text square measure keen a...

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.
