VIRGOS: Secure Graph Convolutional Network on Vertically Split Data from Sparse Matrix Decomposition
·
arXiv:2502.09808v1 Announce Type: new Abstract: Securely computing graph convolutional networks (GCNs) is critical for applying their analytical capabilities to privacy-sensitive data like social/credit networks. Multiplying a sparse yet large adjacency matrix of a graph in GCN–a core operation in training/inference–poses a performance bottleneck in secure GCNs. Consider a GCN with $|V|$ nodes and $|E|$ edges;…

So, I’m looking at a privacy solution for sending myself notes, links, small files, etc between devices instantly. Laptop and desktop on Linux. Phone on Android. So far I’ve successfully set up a Matrix private room with encryption enabled, a Telegram Private Channel, and Signal Note to Self. All devices have each client installed. Security-wise,…

The Matrix botnet is expanding at an alarming rate, with nearly 35 million devices currently vulnerable to compromise. Researchers from Aqua Nautilus who uncovered the threat, warn that even a fraction of these devices falling into the botnet’s control could result in a massive surge in scale, posing significant risks to global cybersecurity infrastructure.

From commodity malware to nuisance worms to sophisticated, targeted attacks, organizations need to protect themselves by reducing exposure to cybersecurity threats. Threats can range from something well-known and understood that somehow lingers on the network to a novel attack targeting control system functionality, intended to cause real-world harm. A useful tool for understanding and knowing how…
