A SURVEY ON ATTRIBUTE BASED ENCRYPTION TECHNIQUES IN 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-ABE, HABE, MA-ABE, KP-ABE

Attribute Based Encryption with Privacy Preserving using Asymmetric Key in Cloud Computing
Symmetric key algorithm uses same key for both encryption and decryption. The authors take a centralized approach where a single key distribution center (KDC) distributes secret keys and attributes to all users. A new decentralized access control scheme for secure data storage in clouds that supports anonymous authentication. The validity of the user who stores the data is also verified. The proposed scheme is to hide the users attributes using SHA algorithm . The Pailier cryptosystem, is a probabilistic asymmetric algorithm for public key cryptography. Pailier algorithm use for Creation of access policy, file accessing and file restoring process and also hiding the access policy to the user using query based algorithm.
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.
Secured and Verifiable Approach for Attribute Based Encryption in Cloud Computing
International Journal of Engineering Sciences & Research Technology, 2014
Cloud Computing has changed the phenomena of IT industry completely. It allows access to highly scalable, inexpensive, on demand computing resources that can execute the code and store data that are provided. But adoption and approach to cloud computing applies only if the security is ensured. Cloud computing is lacking in security, confidentiality and visibility. Secure the cloud means to secure the storage. Security is achieved by the encryption. There are various encryption standards to ensure the cloud security. Attribute-based encryption (ABE) is public key encryption technique that allows users to encrypt and decrypt messages based on user attributes. In a typical implementation, the size of the cipher text is proportional to the number of attributes associated with it and the decryption time is proportional to the number of attributes used during decryption. To reduce the decryption time in cloud outsourced decryption technique is used. By providing a transformation key to the cloud ABE cipher text is converted into simple cipher text and it only incurs a small computational overhead for the user to recover the plaintext from the transformed ciphertext.. To ensure that transformation performed by cloud server is correct and the data is not modified by the untrusted servers proposed system is introduced. This provides secured and Verifiable Outsourced decryption.
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 with Privacy Preserving In Clouds
Security and privacy are very important issues in cloud computing. In existing system access control in clouds are centralized in nature. The scheme uses a symmetric key approach and does not support authentication. Symmetric key algorithm uses same key for both encryption and decryption. The authors take a centralized approach where a single key distribution center (KDC) distributes secret keys and attributes to all users. A new decentralized access control scheme for secure data storage in clouds that supports anonymous authentication. The validity of the user who stores the data is also verified. The proposed scheme is resilient to replay attacks. In this scheme using Secure Hash algorithm for authentication purpose, SHA is the one of several cryptographic hash functions, most often used to verify that a file has been unaltered. The Paillier crypto system, is a probabilistic asymmetric algorithm for public key cryptography. Pailier algorithm use for Creation of access policy, file accessing and file restoring process.

International journal of computer applications, 2021
Emerge of cloud computing technology over the world has caused a revolution in internet. The virtual usage of platform, infrastructure and software over cloud has provided an environment where the user can store and run the application from anywhere. This has led to think about security over data stored over cloud. In this paper, Attribute Based Keyword Search over encrypted data in cloud are discussed which provides security over searching of data based on keyword.

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 ...
