Cs161 project 3.

An End-to-End Encrypted File Sharing System. In this project, you will apply the cryptographic primitives introduced in class to design and implement the client application for a secure file sharing system. Imagine something similar to Dropbox, but secured with cryptography so that the server cannot view or tamper with your data.Project 3 Part 1 Page 2 of 6 CS 161 – Spring 2020 1.

The average score on the coding portion of Project 2 is around 60%, and the score distribution is similar to an exam distribution. Grading We will compute grades from a weighted average, as follows: Homeworks: 10% (equally weighted) Project 1: 10% Project 2: 20% Project 3: 10% Midterm: 20%; Final: 30%

3. User Struct corruption: Because each user struct is Encrypted and Signed with Keys deterministically created based on the user’s username and password, each user is stored in the Data Store with Integrity and Authenticity. If an attacker somehow gained access to the Data Store and and tampered with a User Struct, upon calling GetUser()
