چکیده
The YWRL’s revocable KP-ABE scheme [1] is based on the GPSW KP-ABE scheme [2]. There are eight algorithms in total, where the first four are the same with those in the GPSW scheme. Setup(1). This algorithm takes as input a security parameter κ and an attribute universe U = 1, 2, ..., N . It defines two multiplicative cyclic groups G1 and GT with prime order p, g1 as a generator of G1, and an admissible bilinear map e : G1 ×G1 → GT . The system master key MK and public key PK are generated as:

DoS-Resistant Attribute-Based Encryption in Mobile Cloud Computing with Revocation
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 ...

Scalable and secure sharing of personal health record in cloud computing is an emerging trend in Health field for exchange and the use of personal Health information. This sensitive data is shared and stored by the third party reference in cloud computing. Therefore the need of encrypting data stored at this sites is highly essential to reduce the storage space and for the cost reduction. Since...
متن کاملA Novel Method for Patient Centric Secure and Scalable sharing of PHR in Cloud Computing using Encryption
PHRs grant patients access to a wide range of health information sources, best medical practices and health knowledge. In patient centric secure sharing, patients will create, manage and control their personal health data from one place using the web. Prior to storing the records in cloud server, they are encrypted using encryption algorithm which ensures the patient’s full control over their P...
