Welcome to the blog tracking the Fenrir project
This blog will be used to track and -why not- discuss all the choices, design features and advancements of the project, so you might find both technical posts and random thoughts.

Handshakes Fenrir steteless
While re-implementing the full-security handshake in the rewrite of libFenrir, I came across the old problem of stateful vs stateless handshakes, and what it means for (D)DOS attacks.
After thinking about it for a while, let me introduce you to a slight modification of the full-security handshake to have the best world of bot stateful and stateless handshakes.
We will go through various design, and quickly analyze various solutions from TCP to minimaLT.… (Read More)
What is happening? Has the project stalled?
Not really, I’m just working behind the scenes.
Since you might also like some kind of report, I added a section “currently working on” on the blog page.… (Read More)
Update Fenrir paper ITA-SEC
I submitted a paper highlighting Fenrir to a security conference ITA-SEC.
The paper was rejected. Let’s see why and what it meas for the Fenrir project.
TLDR: no big deal, keep working.… (Read More)
A lot of time passed, what happened?
I have not been slacking, but I have not been working much on Fenrir lately.
That’s because a lot of work has been done in libRaptorQ, that Fenrir will use.
Our ideas differ, so let’s analyze the problem.… (Read More)
I finally had some time to better think about multicast transmission and better analyze the problem. And I think I have a solution.… (Read More)
I finally finished my master thesis, and the result can be found here.
Feel free to look at it to better understand the Fenrir protocol.… (Read More)
bandwidth delay RTT speed satellite
Every protocol has a limit on how quickly it can deliver things.
So how does Fenrir compare to the classical TCP?… (Read More)
federation authentication anonymity
Obviously we support anonymous connection. But that’s not the same as an anonymous login.
By “Anonymous login” we mean being able to login to a 3rd party website without revealing our username.
With Fenrir, that’s pretty simple.… (Read More)
It took me a lot more than expected, but finally I have a working implementation of the RaptorQ algorithm (RFC630)… (Read More)
