Name: Data access control based on the Attribute based encryption with respect to the

Clustered node

· Technologies : .Net

Project Description:

• Attribute-Based Encryption (ABE) is a promising cryptographic primitive which significantly enhances the versatility of access control mechanisms.
• Due to the high expressiveness of ABE policies, the computational complexities of ABE key-issuing and decryption are getting prohibitively high.
• Despite that the existing Outsourced ABE solutions can offload some intensive computing tasks to a third party, the verifiability of results returned from the third party has yet to be addressed.
• Aiming at tackling the challenge above, we propose a new Secure Outsourced ABE system, which supports both secure outsourced key-issuing and decryption.
• Our new method offloads all access policy and attribute related operations in the key-issuing process or decryption to a Key Generation Service Provider (KGSP) and a Decryption Service Provider (DSP), respectively, leaving only a constant number of simple operations for the attribute authority and eligible users to perform locally.

I hereby declare that the information furnished above is true to the best of my knowledge.
