A Fuzzy Operator-Attribute-Based Signcryption Scheme on Vehicular Clouds

Vehicular Computer Clouds (VCC) would be expected to play a major role in the Intelligent Transportation System (ITS) in the near future. While it is clear that the VCC concept raise exceptional security challenges. Generally speaking, most attacks come from operators. So it is important to design the novel VCC security scheme based on operator's attributes. In this paper, we develop the Fuzzy Operator-Attribute-Based Signcryption (FOABS), a novel security mechanism that makes relations between the vehicle operator's right and these operation. FOABS leverages fuzzy Attribute-Based encryption to enable data encryption, access control, and signature for vehicular control information in VCC. FOABS provides confidentiality, authenticity, undeniability, identity authentication, and collusion resistance.
