Blockchain Literature Review
Short Paper
Wrote a short survey paper that reviews various blockchain ecosystem designs and created a GitHub repository with summaries of the papers referenced in the survey.

Broadcast Encryption Based on the Naor-Reingold PRF
Short Paper
Wrote a short research paper that defines a broadcast encryption scheme and proves its security by reduction to the hardness of the discrete logarithm problem.

Padding Oracle Attack
Used the padding oracle attack to decrypt a message encrypted using a block cipher in CBC mode.

Implemented the TCP network protocol API from scratch.

Given a poorly secured website, discovered vulnerabilities and designed and executed exploits to steal unauthorized information and escalate privileges (e.g. SQL injection, parameter based access control, file injection, cross-site scripting, etc.).

Designed and developed a file hosting system which allows multiple users to register for an account and securely authenticate their credentials to upload and download their personal files.

Implemented a program that simulates Bitcoin transactions. Given a list of public keys of the current owners of $n$ coins and a list of $t$ transactions, determines whether each transaction contains a valid ECDSA signature on the Secp256k1 curve, performs the transaction if the signature is valid, and prints the final owners of the $n$ coins.
