With the growing popularization of the Internet of Vehicles (IoVs), the combination of satellite navigation system and IoVs is also in a state of continuous improvement. In this paper, we present a heterogeneous signcryption scheme with group equality test for IoVs (HSC-GET), which avoids the adversaries existing in the insecure channels to intercept, alter or delete messages from satellite to vehicles. The satellite is arranged in an identity-based cryptographic (IBC) system to ensure safe and fast transmission of instruction, while the vehicles are arranged in certificateless cryptosystem (CLC) to concern the security of the equipment. In addition, the group granularity authorization is integrated to ensure the cloud server can only execute the equality test on ciphertext generated by the same group of vehicles. Through rigorous performance and security analyses, we observe that our proposed construction reduces the equality test overhead by about 63.96%, 81.23%, 80.84%, and 54.98% in comparison to other competitive protocols. Furthermore, the confidentiality, integrity and authenticity of messages are guaranteed.
