A Novel Intrusion Detection Model for a Massive Network Using Convolutional Neural Networks
TLDR
This paper proposes a novel network intrusion detection model utilizing convolutional neural networks (CNNs), which uses CNN to select traffic features from raw data set automatically, and sets the cost function weight coefficient of each class based on its numbers to solve the imbalanced data set problem.

A flexible policy-based access control model for Workflow Management Systems
TLDR
A novel dynamic access control model which incorporates authorization policies to meet the particular requirement of WFMSs, named PBFW is proposed, which enforces separation of duty (SoD) policies during runtime and supplies access control of appropriate granularity for WfMSs.

An Efficient ECC-Based CP-ABE Scheme for Power IoT
TLDR
A novel CP-ABE scheme based on elliptic curve cryptography (ECC) is proposed, which replaces the bilinear pairing operation with simple scalar multiplication and outsources most of the decryption work to edge devices and solves the performance bottleneck of having a single authority.
