• Blockchain for Distributed Multimedia Evidences

- Use blockchain (Ethereum) to store multimedia crime evidences in order to protect forgery.

• Bandwidth-constrained Long-Range Video Transmission

- Amid a national park without any commercial signals, use LoRa (Long Range), a Low Power, Wide Area networking protocol, to transmit the captured pictures of illegal hunting inside the restricted area.

USC Information Sciences Institute (ISI) 2019 — present Research Assistant at STEEL supervised by Prof. Jelena Mirkovic

• AMON-SENSS

- A scalable DDoS detection for ISPs.

- Implement various anomaly detection approaches and tested them individually with the real captured traffic. Then compare a detection result from each approach with the ground truth to verify its accuracy.

• Quantifying Cloud Misbehavior

- Published at the 9th IEEE International Conference on Cloud Networking (IEEE CloudNet 2020).

- Gather several datasets containing unwanted internet traffic. Then classified /24 network prefixes into “cloud” or “not-cloud”.

- Since there is no universal ground truth that determine whether a given network address is a cloud provider or not, we identify “cloud” based on various sources like reverse DNS lookup, data from Alexa Top 500 hosting services and data from IPinfo.io.

- Aggregate this collected data into the list of /24 cloud prefixes and use it to quantify the amount of traffic originated from cloud providers in each dataset.

• Privacy Leaks from Venmo Application

- Apply BERT, a pre-training model for NLP, to classify Venmo public transactions as “sensitive” or

“not-sensitive”

- Will publish soon (under preparation)

• Improving Coverage for Estimating DNS RTT

- Improve coverage for DNS to estimate its client latency

- Previous works suggested that DNS client latency could be estimated from TCP handshake time. However, TCP was not widely used in DNS and consequently limited a proposed method to poor coverage. As previous works mentioned, using a truncated bit (TC bit) might overcome a coverage problem. Note that DNS uses a TC bit to ask clients to retry their UDP query over TCP.

- Following their suggestion, modify authoritative server code (KNOT DNS) to ask some clients to retry their queries over TCP using a TC bit.

- Evaluate how coverage improves

- Write an academic paper and present it on a poster Conference Attended
