A Resource-Friendly Certificateless Proxy Signcryption Scheme for Drones in Networks beyond 5G

Security and privacy issues were long a subject of concern with drones from the past few years. This is due to lack security considerations in design drone, which includes unsecured wireless channels insufficient computing capability perform complex cryptographic algorithms. Owing extensive real-time applications ubiquitous connection beyond 5G (B5G) networks, efficient measures are required prevent unauthorized access sensitive data. In this article, we proposed resource-friendly proxy signcryption scheme certificateless settings. The was based on elliptic curve cryptography (ECC), has reduced key size, i.e., 80 bits, is, therefore, suitable for drones. Using random oracle model (ROM), analysis performed shown be secure against well-known attacks. performance also compared relevant existing schemes terms computation communication costs. findings validate practicability scheme.
