Hesitant Pythagorean fuzzy Maclaurin symmetric mean operators and its applications to multiattribute decision‐making process

Abstract: Hesitant Pythagorean fuzzy (HPF) sets can easily express the uncertain information while Maclaurin symmetric mean (MSM) operator, can capture the interrelationship among the multiattributes, and are suitable for aggregating the information into a single number. By taking the advantages of both, in this paper, we extend the traditional MSM to HPF environment. For this, we develop the HPFMSM operator for aggregating the HPF information. The desirable characteristics, such as idempotency, monotonicity, and boundedness, are studied. Then, we discussed some special cases with respect to the parameter value of the HPFMSM operators and showed that it generalizes the various existing operators. Furthermore, we studied the weighted HPFMSM operator to aggregate the HPF information with different preferences to the input arguments. On the basis of these operators, we solved the multiattribute decision‐making problems with HPF information. The practicality and effectiveness of the developed approach are demonstrated through a numerical example.

On the Design of Conditional Privacy Preserving Batch Verification-Based Authentication Scheme for Internet of Vehicles Deployment

Abstract: In the Internet of Vehicles (IoV), secure information sharing among vehicles is crucial in order to upgrade driving safety as well as to strengthen vehicular services. However, public communication among vehicles leads to various potential attacks, such as replay, man-in-the-middle, impersonation, unlinkability and traceability attacks. To address this issue, we design a new conditional privacy preserving batch verification-based authentication mechanism in the IoV environment using Elliptic Curve Cryptography $(ECC)$ technique, where a vehicle can authenticate its neighbor vehicle and also a Road-Side Unit $(RSU)$ can authenticate its nearby vehicles in a batch. The proposed scheme is shown to be highly secure against a passive/active adversary through various security analysis, such as random oracle based formal security, formal security verification via automated simulation tool, and also informal security analysis. An exhaustive comparative analysis reveals that the proposed scheme offers better security and functionality attributes, and comparable storage, communication and computation overheads when these are compared with the relevant schemes.
