SmartSecChain-SDN: Smarter, Safer Software-Defined Networks

As more networks switch to Software-Defined Networking (SDN), keeping them both safe and speedy is a challenge. SmartSecChain-SDN is a new framework that tackles both.

It blends three pieces:

AI intrusion detection using Random Forest, XGBoost, CatBoost, and a CNN-BiLSTM to spot attacks in real time with high precision.
Tamper-resistant logs stored on Hyperledger Fabric, a permissioned blockchain, so security records stay private, consistent, and auditable.
App-aware QoS that prioritizes critical traffic (VoIP, video meetings, business apps) and slows non-essential flows (bulk downloads, updates).

Using Mininet with OpenDaylight and Ryu controllers, the team tested on the InSDN dataset and showed the system can detect diverse cyberattacks while fairly allocating bandwidth under tight resources.

Bottom line: SmartSecChain-SDN offers a practical path to stronger cybersecurity, easier compliance, and smoother performance in next-gen programmable networks.

Automating GDPR Compliance: A Roadmap for Companies and Law Firms

GDPR compliance is more than checkboxes. A new roadmap from the Privatech project shows how automation and machine learning can help companies and law firms assess—and even generate—privacy compliance. * Shift the focus to data processors’ real workflows: drafting policies, mapping data uses, documenting decisions. * Break compliance into machine-ready

FPGAs for Faster, Leaner Deep Learning: A Review of CNN Accelerators

Deep learning drives image search, robots, and medical scans. Most systems lean on CPUs and GPUs. This review asks: what if we run convolutional neural networks (CNNs) on FPGAs—reconfigurable chips you can tailor to the model? * Why FPGAs: custom dataflows, low latency, and strong energy efficiency—great for cameras,

Dynamic-K: Recommendations That Know When to Stop

Most apps show a fixed number of “top” items—say 10 movies or 20 products—assuming there are always enough good options. But that’s not always true: sometimes there are few relevant items, or some users are extra picky. The result? Filler recommendations. Dynamic-K flips the script. Instead of

Teaching chatbots to stop contradicting themselves (DECODE)

Teaching chatbots to stop contradicting themselves Ever had a bot say one thing, then the opposite a few turns later? This study introduces DECODE—a new task and dataset for spotting contradictions in everyday conversations, drawn from both human-human and human-bot chats. * New data beats existing natural language inference (NLI)
