A new construction of fuzzy operator-attribute-based signcryption on VCC

Recently, vehicular computer clouds (VCC) have taken an important role in intelligent transportation systems (ITS). VCC meets lots of security challenges, it is important to build secure VCC access. In this paper, a fuzzy operator-attribute-based signcryption (FOABS) is presented, which is a novel security mechanism that makes relations between the vehicle operator's right and these operations. FOABS leverages fuzzy attribute-based encryption to enable data encryption, access control, and signature for vehicular control, and signature for vehicular control information in VCC. FOABS, which combines digital signatures and encryption, provides confidentiality, authenticity, undeniability, and collusion resistance. Through the prototype system, we analyse its security level.
