Internet of Drones (IoD) is considered as a network and management architecture, which can enable unmanned aerial vehicles (UAVs) to collect data in controlled areas conduct access control for UAVs. However, the current cloud-assisted IoD scheme cannot efficiently achieve secure communication between heterogeneous cryptosystems, does not support multi-ciphertext equality tests. To improve security performance traditional schemes, we propose signcryption (HSC-MET) that supports test. In this paper, use test technique multi-user simultaneous retrieval multiple ciphertexts safely efficiently. addition, adopt technology realize from public key infrastructure (PKI) certificateless cryptography (CLC). At same time, proposed based on computation without bilinear pairing, greatly reduces computational cost. According analysis, under random oracle model (ROM), confidentiality, unforgeability number HSC-MET are proved Diffie-Hellman (CDH) problem.
