Post-doctoral researcher, Network Security Lab

Shana Moothedath 

I am a postdoctoral research scholar in Network Security Lab at University of Washington, Seattle working with Prof. Radha Poovendran & Prof. Linda Bushnell. I recently obtained my Ph.D. from Deaprtment of Electrical Engineering at Indian Institute of Technology Bombay where I was supervised by Prof. Prasanna Chaporkar & Prof. Madhu N. Belur. My current research is in the intersection of security, control, machine learning, game theory, and protocols.

Educational Background

Instructor for:

  • Autumn 2019: EE 418 Network Security and Cryptography

    The goal of this course is to develop an understanding of the fundamental principles of cryptography and its application to network and communication security. This course will serve as an introduction to the fundamental tools in cryptography and the protocols that enable its application to network and communication security. In details this course serves an introduction to the basic theory and practice of cryptographic techniques used in computer security. We will cover topics such as encryption (secret-key and public-key), digital signatures, authentication of entities, key management, cryptographic hashing, wireless security. The course projects are used to introduce emerging topics such as RFID security, sensor network security, modeling and mitigation of attacks, privacy in social networks.
  • Prerequisites: MATH 308 (linear algebra, matrix) or MATH 390, STAT 390 or IND E 315 (prob. and stats.), or permission from the instructor.

  • List of topics:

    • Introduction to classical Cryptography and Cryptanalysis

    • Motivation and introduction to hash functions
