TL;DR: This paper proposes a new data sharing protocol for cloud computing by using a new cryptographic primitive named online/offline attribute-based proxy re-encryption and the transform key technique, and is the first one featuring with fine-grained access control, flexible sharing, data confidentiality, and minimum online computational cost on the user side at the same time.

TL;DR: A secure same-symptom-based handshake (SSH) scheme is proposed, and the provable security technique is applied to demonstrate its security in the random oracle model.

TL;DR: Analytical results show that better location privacy can be achieved when a vehicle changes its pseudonyms at some highly social spots, and as a result, the proposed models can be used to assist vehicles to change their pseudonyms for better location Privacy at the right moment and place.

TL;DR: A new lightweight conditional privacy preservation (LCPP) protocol utilizes simple hash-chain techniques to secure VTM systems and achieves efficient local revocation verification on the road.

TL;DR: A new cross-layer relay-resistant authentication protocol is designed by leveraging the distance-bounding technique to prevent a degradation-of-QoS attack against vehicular ad hoc networks (VANETs).
