Mid-term Project

Contact: Lao Chon Lam
Timeline:

1. Before 04/01 11:59PM:
   1. Choose a primtive in the project
   2. Reserve it on the "Class Discussion" in the Web Learning Portal
   3. Notify Lao Chon Lam about your choice by email.
2. Before 04/17 11:59PM: Submit your report and code to Web Learning Portal

Project Description
In this project, we would benchmark various crypto primitives.

1. Choose one crypto primitive implementation: AES, RSA, ECC, DSA, PSS, SHA-1, MD5, X.509 Certificate
2. Choose an existing industrial library, e.g., Crypto++, pycrypto.
   You had better choose an advanced implementation, e.g., AES NI on Intel CPU, or GPU implementation.
3. Profile the primitive you choose
   1. (High Priority) You are preferred to first search whether there are existing benchmarks in the industry and the academia to measure the implementation of these primitives. If there exists, use the benchmark first; otherwise, design your own experiment.
   2. List parameters in your experiment, e.g., message length, randomness of messages/keys, and any other parameters you can think up.
   3. The metrics to profile them, e.g., encryption/decryption speed, memory usage, and any other metrics you can think up.
4. Write a report
   1. The primitive you choose, and the parameters in your experiment
   2. The environment in your experiment: the hareware of your computer, the OS, and the library you use.
   3. The metrics you measured in your experiment.
   4. The visualized figure your measured metrics. (Experiments need to be repeated to get the average and the error bar.)
