N2 - VCC (Vehicular Cloud Computing) is an emerging and promising paradigm, due to its significance in traffic management and road safety. However, it is difficult to maintain both data security and system efficiency in Vehicular Cloud, because the traffic and vehicular related data is large and complicated. In this paper, we propose a conditional ciphertext-policy attribute-based encryption (C-CP-ABE) scheme to solve this problem. Comparing with CP-ABE, this scheme enables data owner to add extra access trees and the corresponding conditions. Experimental analysis shows that our system brings a trivial amount of storage overhead and a lower amount of computation compared with CP-ABE.
