Eagle Eye: Wi-Fi Monitoring
EagleEye, a wireless network monitoring tool built for non-technical users: a 815-person survey on why people need it, then the architecture — libtins/dot11decrypt decrypting live monitor-mode packets, Scapy filtering them, and a Flask server feeding simple graphs to the browser. With git repo, paper, and PDF.

Introduction to Supersingular Isogeny Diffie-Hellman
An approachable introduction to Supersingular Isogeny Diffie-Hellman (SIDH) — one of the few post-quantum key exchanges built on elliptic curves — written for an Elliptic Curve Cryptography course: its motivation, the math you need (isogenies, the j-invariant, supersingular curves), the key exchange itself, and Costello et al.'s recommended parameters. Rebuilt from the original LaTeX, led in by the post's own blurb.

SoundCloud Spam Analysis
Crawling 20 million SoundCloud users with a Docker crawler army (and a "borrowed" public API key), then using K-Means clustering and a Keras neural net to find and predict spam accounts — with dataset, paper, code, and PDF at the end.

Survey of Cryptographic Implementations and Vulnerabilities on Passive RFID Devices
A 20-page survey paper (UCSB) on the cryptography of passive RFID tags — system and adversary models, the attack landscape, the famous Mifare and DST breaks, and mitigation strategies — rebuilt from the original LaTeX, led in by the post's own plain-English "quick version."

Calculating Nonlinearity of Boolean Functions with Walsh-Hadamard Transform
A short cryptography paper (UCSB) on what nonlinearity means for boolean functions and how to measure it with the Walsh-Hadamard transform — rebuilt from the original LaTeX with a live calculator: flip an 8-bit truth table and watch its Walsh spectrum and nonlinearity recompute.

Physical Unclonable Functions
A grad-class intro to PUFs — hardware functions whose challenge-response mapping falls out of physical manufacturing variation — covering their key principles, types, properties, and the intra-/inter-distance math used to measure them.
