Collaborative Multi-Authority KP-ABE for Shorter Keys and Parameters
Bilinear groups are often used to create Attribute-Based Encryption (ABE) algorithms. In our proposal, a Multiple-Authorities Key-Policy Attribute-Based Encryption scheme is constructed in which the authorities collaborate to achieve shorter keys and parameters, enhancing the efficiency of encryption and decryption. We prove our system secure under an original variation of the bilinear DiffieHellman assumption, we also show its relation with other similar assumptions.
