A Survey on Data Sharing Using Encryption Technique in Cloud Computing
نویسنده
چکیده
A model by which information technology services being delivered is resources are retrieved from the internet through web-based tools and applications, instead of direct connection to a server. The Data and software packages are stored in servers. However, cloud computing structure allows access to information as long as an electronic device has access to the web. In this technology users have to entrust their data to cloud providers, there are several security and privacy concerns on outsourced data. In this paper, survey on several schemes such as Key-Policy Attribute-Based Encryption, Ciphertext-Policy AttributeBased Encryption, Ciphertext Policy Attribute Set Based Encryption, Fuzzy Identity-Based Encryption, Hierarchical Identity-Based Encryption, Hierarchical Attribute-Based Encryption and Hierarchical Attribute-SetBased Encryption for access control of outsourced data are discussed. Keywords— Cloud computing; data confidentiality; finegrained access control.

While cloud computing is growing at a remarkable speed, privacy issues are far from being solved. One way to diminish privacy concerns is to store data on the cloud in encrypted form. However, encryption often hinders useful computation cloud services. A theoretical approach is to employ the so-called fully homomorphic encryption, yet the overhead is so high that it is not considered a viable s...

Security and privacy are very important challenges for outsourced private data over cloud storages. By taking Attribute-Based Encryption (ABE) for Access Control (AC) purpose we use fine-grained AC over cloud storage. In this paper, we extend previous Ciphertext Policy ABE (CP-ABE) schemes especially for mobile and resource-constrained devices in a cloud computing environment in two aspects, a ...

متن کاملA Survey on Attribute Based Encryption to Improve Efficiency in Semantic Search Over Cloud Data
Mobile cloud computing provides the capability of sharing of the data that is encrypted with different user through cloud Storage. This raises the point of security issues over data confidentiality and authentication access control. The blind storage allows a client to store the number of files on remote server, where remote server is not familiar with the files that are stored in it. In Attrib...
