Title:
Collaborative Multi-Authority Key-Policy Attribute-Based Encryption for Shorter Keys and Parameters

Authors: Riccardo Longo, Chiara Marcolla, Massimiliano Sala

Abstract:

Architectures relying on a single central authority often offer a great efficiency, but suffer of resiliency problems and are quite vulnerable to attacks. In our proposal, a Multiple-Authorities Key-Policy Attribute-Based Encryption scheme is constructed including a collaboration phase between the authorities, in order to achieve shorter keys and parameters, thus enhancing the efficiency of encryption and decryption. \ We prove our system secure under a variation of the bilinear Diffie-Hellman assumption, providing a lower bound on its complexity.
