TL;DR: This paper proposes an efficient and geometric range query scheme (EGRQ) supporting searching and data access control over encrypted spatial data, and employs secure KNN computation, polynomial fitting technique, and order-preserving encryption to achieve secure, efficient, and accurate geometricrange query over cloud data.

TL;DR: This article argues that public key infrastructure is the most viable mechanism for securing VANets as it can meet most VANET security requirements, and introduces complementary security mechanisms that can meet the aforementioned security requirements.

TL;DR: This paper proposes an efficient cooperative authentication scheme for VANETs that maximally eliminates redundant authentication efforts on the same message by different vehicles, and uses an evidence-token approach to controlling the authentication workload, without the direct involvement of a trusted authority.

TL;DR: A light-weight and robust security-aware D2D-assist data transmission protocol for M-health systems is proposed by using a certificateless generalized signcryption (CLGSC) technique and performance analysis demonstrates that the proposed protocol can achieve the design objectives and outperform existing schemes in terms of computational and communication overhead.

TL;DR: A secure same-symptom-based handshake (SSH) scheme for social-based patient health information (PHI) collaborative reporting in MHSN is proposed, and extensive simulations are conducted to evaluate its efficiency in terms of PHI delivery ratio and reporting delay.
