Uh oh, I think those were the right launch codes 🙀

I'm now able to build trees to share an encryption key to a set of authorized devices (if you know the AACS scheme, it's the part that's used to derive the processing key in a media key block). Blog article coming when it's done™

A test program that prints the number of revoked nodes within a tree, and the emitted subset-difference entries for each tree.

A picture of a toy tree of depth 5 and a list of revoked devices, alongside their assigned their revoked keys, to check if none of the assigned keys can covered the subset-difference records.

Today, I've had fun with Hookpad, to decipher a key change that messed with my brain in "Inori" from Fujikawa Chiai. Might share it on Theorytab in two weeks, my profile is too young to submit entries... For the record, the section of interest is @2:49 in this video: www.youtube.com/watch?v=3l4Y...

Screenshot of Hookpad music composition software showing the song 'Inori' by Chiai Fujikawa in D♭ major. The view displays Chorus, Bridge, and Verse 2 sections, each with a piano-roll melody and a row of Roman-numeral chord symbols. A side panel shows voice and display settings, and a bottom bar has audio playback controls.

Having a dissector for a protocol which spec is not yet completed, nor public: check.

AX.25 Authentication Header

## Status of this Memo
This document specifies an Amateur Radio protocol, and requests discussion and suggestions for improvements. Distribution of this memo is unlimited.

## Copyright Notice

Copyright (C) 2026 Célestine Gramaize F4HOF

## Introduction

The AX.25 Authentication Header (AX.AH) is used to provide connectionless integrity and data origin authentication for AX.25 datagram (hereafter referred to as just "authentication"), and to provide protection the default calls for the sender to increment the Sequence Number against replays. AX.AH provides authentication for as much of the AX.25 header as possible, as well as for upper level protocol data. However, some AX.25 header fields may change in transit and the value of these fields, when the packet arrives at the receiver, may not be predictable by the sender. The values of such fields cannot be protected by AX.AH.

The keywords MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD, SHOULD NOT, RECOMMENDED, MAY, and OPTIONAL, when they appear in this document, are to be interpreted as described in [RFC 2119}(https://datatracker.ietf.org/doc/html/rfc2119).

Security services can be provided between a pair of communicating hosts, between a pair of communicating security gateways, or between a security gateway and a host.

Anohana made me notice those two bridges look quite similar: On your left: Chichibu bridge (Saitama prefecture, JP) On your right: Pertuiset bridge (Loire, FR)

Chichibu Bridge (Japan)
Completed in 1985, this is a single-span, single inverted-Y pylon, cable-stayed road bridge.

Pont du Pertuiset (France)
Completed in 1988, this is also a single-span, single inverted-Y pylon, cable-stayed road bridge, located in Unieux, Loire, crossing the Loire River.

Out of 9 phases, you can recover up to 4 bits for 4 transitions, more than 1 bit for 4 transitions, and the last, which is the XOR of the 3 previous bits.
