SECURED ATTRIBUTE BASED DATA SHARING
Project Abstract / Summary : With the recent adoption and diffusion of the data sharing paradigm in distributed systems , there have been increasing demands and concerns for distributed data security. One of the most challenging issues in data sharing systems is the enforcement of access policies and the support of policies updates. Ciphertext policy attribute-based encryption (CP-ABE) is becoming 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. However, the advantage comes with a major drawback which is known as a key escrow problem. The key generation center could decrypt any messages addressed to specific users by generating their private keys. This is not suitable for data sharing scenarios where the data owner would like to make their private data only accessible to designated users. Therefore, in this PROJECT, we propose a novel CP-ABE scheme for a data sharing system by exploiting the characteristic of the system architecture. The proposed scheme features the following achievements: 1) the key escrow problem could be solved by escrow-free key issuing protocol, which is constructed using the secure two-party computation between the key generation center and the data-storing center, and 2) fine-grained user revocation per each attribute could be done by proxy encryption which takes advantage of the selective attribute group key distribution on top of the ABE.
Why did you choose to work on this project topic : Now a days the technology demads are get increased rapidly.Information security is one of the aspect on which every organization in the whole world spending lots of money. So we think that why not we reduce this burden on the society by using effective algorithms and approaches.
