A Lightweight Hybrid Signcryption Scheme for Smart Devices
Lanlan Pan, Ruonan Qiu, Minghui Yang · 2024
With the widespread of smart devices, a massive number of messages are sent through message applications every day. Currently, most message applications have been designed for single-receiver and group-receiver scenarios. Moreover, the sender device may send messages to multiple-receiver devices selected from the group device set. In this paper, we propose a lightweight hybrid signcryption scheme supporting the single-receiver and multiple-receiver scenarios, which are compatible with the group-receiver scenario. The formal verification results show that our scheme can offer confidentiality and authentication and is resistant to key-compromise impersonation (KCI) attacks. The evaluation results show that it provides an efficient solution with lower compute time and smaller payload size, which is suitable for lightweight message delivery.
