Implementing Dragonblood CVE-2019-9494 - Review

Background

As part of the Advance Workshop in Implementation of Cryptographic Attacks, we were instructed to implement a cache side channel attack library. As a demonstration, we attempted to implement the exploit in CVE-2019-9494[0], using our Cache side channel attack library "Artik" [1].

While we were able to implement the procedure as specified in the paper[2], we were unable to recreate the results described there. In the following review, we are to go over our attempt.

Java Cheatsheet

General concepts you've got to understand so everything could possibly make sense to you.

How a method is called

In java we have 2 concept of calling methods[1]:

• Static dispatching - The Java compiler knows in compile time which function code block to call

• Dynamic dispatching - The Java compilers inserts a code, that on runtime decides which function code block to call
