TL;DR: A new secure channel-free certificateless searchable public key encryption with multiple keywords scheme for IIoT deployment and demonstrates the security of the scheme in the random oracle model against two types of adversaries.

TL;DR: A certificateless public key authenticated encryption with keyword search scheme is proposed, which is provably secure against inside keyword guessing attack (IKGA) and demonstrates that it is more secure and effective compared with other certificatelesspublic key encryption with keywords search schemes.

TL;DR: A new authenticated key agreement protocol without bilinear pairing is designed that achieves mutual authentication, generates a securely agreed session key for secret communication, and supports privacy protection in fog-based VANETs.

TL;DR: Security analysis indicates that the scheme is secure resist chosen keyword and keyword guessing attacks in random oracle model and the computation costs of KeyGen, CLPEKS, Trapdoor and Test phases decreased by 84.68%, 55.04%, 36.1% and 28.73%, respectively.

TL;DR: This work presents a certificateless searchable public key authenticated encryption scheme with designated tester (CL-dPAEKS), which it is claimed is suitable for cloud-assisted mIoT and more secure than other schemes that built on certificateless cryptography, without significant loss in efficiency.
