FESR: A Framework for Eliciting Security Requirements Based on Integration of Common Criteria and Weakness Detection Formal Model

2017

It is critical and foremost to come up with the corresponding security requirements first which the following implementations are based on. However, previous security requirement elicitation work based on Common Criteria (CC) rarely addresses the …

A Low-Storage-TTP and Abuse-Free Contract Signing Protocol Based on the Schnorr Signature

2017

A well-designed contract signing protocol should be fair, optimistic, abuse-free and efficient, which, however, cannot be realized concurrently, especially in some cases is a trade-off problem. In fact, most existing relevant protocols are difficult to …

Graph Agent Network: Empowering Nodes with Inference Capabilities for Adversarial Resilience

2025 · Proceedings of the AAAI Conference on Artificial Intelligence

End-to-end training with global optimization have popularized graph neural networks (GNNs) for node classification, yet inadvertently introduced vulnerabilities to adversarial edge-perturbing attacks. Adversaries can exploit the inherent opened interfaces of GNNs' input and output, perturbing …
