Searchable attribute-based encryption scheme with attribute revocation in cloud storage
Attribute based encryption (ABE) is a good way to achieve flexible and secure access control to data, and attribute revocation is the extension of the attribute-based encryption, and the keyword search is an indispensable part for cloud storage. The combination of both has an important application in the cloud storage. In this paper, we construct a searchable attribute-based encryption scheme w...
متن کاملEfficient Attribute-Based Searchable Encryption on the Cloud Storage
Cloud computing is very popular for its computing and storage capacity at lower cost. More and more data are being moved to the cloud to reduce storage cost. On the other hand, since the cloud is not fully trustable, in order to protect data privacy against third-parties and even the cloud server, they are usually encrypted before uploading. However, many operations, such as searching, are hard...
متن کاملEfficiently Multi-User Searchable Encryption Scheme with Attribute Revocation and Grant for Cloud Storage
Cipher-policy attribute-based encryption (CP-ABE) focus on the problem of access control, and keyword-based searchable encryption scheme focus on the problem of finding the files that the user interested in the cloud storage quickly. To design a searchable and attribute-based encryption scheme is a new challenge. In this paper, we propose an efficiently multi-user searchable attribute-based enc...
متن کاملPrivacy-preserving Attribute Based Searchable Encryption
Attribute Based Encryption (ABE) is a promising public-key cryptographic primitive that can be used for cryptographically enforced access control in untrusted storage. Storing data on untrusted storage not only requires data security for data owners but also poses data protection from untrusted storage server. To address this important requirement, Anonymous Attribute Based Encryption (AABE) is...
متن کاملCryptanalysis of Searchable Anonymous Attribute Based Encryption
Ciphertext Policy Attribute Based Encryption (CP ABE) is a public key primitive in which a user is only able to decrypt a ciphertext if the attributes associated with secret key and the access policy connected with ciphertext matches. CP-ABE provides both confidentiality and access control to the data stored in public cloud. Anonymous CP-ABE is an adaptation of ABE where in addition to data con...
