Verifying Outsourced Decryption of CP-ABE with Signature [PDF]
Proceedings of the 4th International Conference on Mechatronics, Materials, Chemistry and Computer Engineering 2015, 2015 Attribute-based encryption enables users to encrypt and decrypt messages based on user attributes. The computational complexities of decryption are very high. By Outsourcing decryption to the third party, it can address the problem. But the verifiability of results returned from the third party has yet to be addressed. In this paper, we introduce short
