covfefe packet switched network - user routing - hiding hop counts/ routing info, from intermediate nodes and GPAs
by Zenaan Harkness 21 Oct '19

21 Oct '19

Example: A routes packet P, via nodes B then C, to node D. Nodes: A B C D PK means "public key", each node knows the PK of the other nodes it communciates with or routes to. Using PK is shorthand - actual encrypted link usually uses PK crypto to negotiate a symmetric session key, which might be changed over time and other complexities, but for the purpose of comprehending basic implementation steps and understanding issues arising, it's sufficient to think in simpler terms of just per node public keys. "Physical" hops in the following example routes: AB BC CD "Virtual" routes we can consider in examples: AB ABC ABCD and also BC, BD, and CD Each hop, e.g. AB, needs their comms to be encrypted to protect from eves droppers. So when A sends P to B, P is encrypted with B's PK. We can use a notation like B(P) to mean encrypt P with B's PK. Similarly notation B'(B(P)) to mean decrypt B(P) to get the raw/unencrypted packet P, from the encrypted version B(P). 1) A sends P only to B 1.1 A encrypts P to B, i.e. sending B(P) to B 1.2 B decrypts, doing B'(B(P)) to get P 2) A sends P to C, via B A wants B to not read P, only to forward C(P) on to C; So, naievely, A sends C(P) to B, with a request to forward C(P) onwards to C. This is naieve, since two problems arise: i) A's request to B is not encrypted, only P is encrypted as C(P). ii) A sends the encrypted packet C(P) first to B (with the routing instruction), and then B also sends C(P) (without any additional routing instructions), to C, but the same set of encrypted bytes has been sent first via AB, and second via BC; the obvious problem with this is that an onlooker (GPA), can simply see that "something" (encrypted) has been sent from A to C, which defeats the purpose of A sending via B at all - there is no benefit over just sending C(P) directly to C. This particular sub-problem can be solved in a couple of immediate ways: I) B receives C(P) from A, so instead of sending that to C, it sends C(C(P)) to C, which C can decrypt, but C needs to know, or guess how many layers to unwrap, and this puts extra unnecessary load on C - the more hops, the more load on the end point of the route, aka not good. II) A first encrypts P using C's PK, then does similarly for node B, so sending B(C(P)) to B, which B decrypts to get C(P), which B can on-send to node C with no extra encryption effort! This puts the load on A, to encrypt its packets according to the total route desired. This is logical, as A wants to minimize trust in any downstream nodes, so doing the work yourself pays off with certainty and less need for trust, greater privacy, and while A is at it, it can embed the required routing header for each hop, into the appropriately layer, thus encrypting all routing requests. A routing header can be denoted with the letter "r", followed if needed by the node letter for the target node of the route request, e.g. "rC" means "route this packet to node C". So for A to 'properly' send P to node C: 2.1 A sends B(rC+C(P)) to node B 2.2 B decrypts, getting rC + C(P) 2.3 B sends C(P) to node C An obvious information exposure bug in steps 2.1 and 2.3 is that the unless we somehow compensate for this, the packet B(rC+C(P)), is larger than the packet C(P) - so our GPA snoop can see that A's packet sent to B, is larger than B's packet sent to C, and it's not hard to guess that the difference is gonna be routing information. The simple solution to different packet sizes is to rely on B to pad C(P) with some random bytes (which need to be ignored by C), so that it's the same size as B(rC+C(P)). But this means once again, relying on B to do the right thing here. Can we get around this reliance on B? The problem only gets worse as we go to an example that includes the next hop, CD... Separating routing requests into separate packets ("control" packets or whatever we might call them) would have downsides of extra buffering and latency to handle dropped packets, packet sequence problems (we're talking UDP here), lower-level packet routing timing issues, requests to resend packets that don't arrive after a timeout etc etc. This is way too complex (reimplementing TCP basically), so forget that - routing requests must be embedded, attached or otherwise be very closely associated, with the packets being routed. Whether routing info is a "tag", a "byte", an IP (v4 or v6) address or etc doesn't matter - a smaller header doesn't make the problem go away, AFAICS.

"Liberal" EU (Spain): decades of jail for individuals who literally organised a referendum! - Democratic Liberalism in Action! - [PEACE]
by Zenaan Harkness 19 Oct '19

19 Oct '19

Joyous news today, folks! Wonders never cease, and finally we see some REAL democracy in the EU's Spain, as Catalan leaders are finally dealt justice with harsh multi year jail sentences - the longest for 13 years. This might finally teach Liberal EU citizens that democracy is putting its foot down when it comes to citizens organizing their own referendums! Really, what were these plucky Catalonians even thinking? Running a referendum for independence in the face of a centuries long willful stand by the majority of Catalonians? Please, compliance -is- willfulness for all you funny rebels :) At least someone, Spain's Supreme Court in this case, had the balls to slap down these plucky "the people's' will first" campaigners. Democracy shall NOT be slighted. At least not the EU. LOL, so funny. The prison roll from the last couple days: Weep For Catalonia - Separatist Leaders Handed Vicious Prison Terms https://www.zerohedge.com/geopolitical/weep-catalonia-separatist-leaders-ha… https://www.craigmurray.org.uk/archives/2019/10/weep-for-catalonia-weep-for… As The BBC reports, Spain's Supreme Court has sentenced nine Catalan separatist leaders to between nine and 13 years in prison for sedition over their role in an independence referendum in 2017. The prosecution had sought up to 25 years in prison for Oriol Junqueras, the former vice-president of Catalonia and the highest-ranking pro-independence leader on trial. Junqueras was handed the longest sentence of 13 years for sedition and misuse of public funds. Others to receive prison sentences for sedition were: - Dolors Bassa, former Catalan labour minister (12 years) - Jordi Turull, former Catalan government spokesman (12 years) - Raül Romeva, former Catalan external relations minister (12 years) - Carme Forcadell, ex-speaker of the Catalan parliament (11.5 years) - Joaquim Forn, former Catalan interior minister (10.5 years) - Josep Rull, former Catalan territorial minister (10.5 years) - Jordi Sànchez, activist and ex-president of the Catalan National Assembly (9 years) - Jordi Cuixart, president of Catalan language and culture organisation Òmnium Cultural (9 years) The nine leaders, who had already spent months in pre-trial detention, were acquitted of a more serious charge of rebellion. https://www.bbc.com/news/world-europe-49974289 That an attempt to organise a democratic vote for the Catalan people in pursuit of the right of self determination guaranteed in the UN Charter, can lead to such lengthy imprisonment, is a plain abuse of the most basic of human rights. I was forced to withdraw my lifelong personal support for the EU when, in response to the vicious crushing of the Catalan referendum by Francoist paramilitary forces, when the whole world saw grandmothers hit on the head and thrown down stairs as they attempted to vote, all the institutions of the EU – Council, Commission and Parliament – lined up one after the other to stress their strong support for the Madrid paramilitary action in maintaining “law and order”. Today we see the same thing. As the Catalans are imprisoned for efforts at democracy, the EU Commission stated that it “respects the position of the Spanish judiciary” and “this is, and remains, an internal matter for Spain, which has to be dealt with in line with its constitutional order.” The Commission here is simply ignoring what is very obviously a fundamental breach of basic human rights. This is far worse than anything Poland or Hungary have done in recent years, and the Commission is also showing a quite blatant hypocrisy in its relative treatment of its Western and Eastern members. ... A million people are expected to march on Saturday in support of the EU. That is the EU which has just expressed its active support for the jailing of Catalans for holding a vote. They join Julian Assange as political prisoners in the EU held for non-violent thought crime. OMG, grandmothers being hit on the head by police - so funny what humans think they can get away with - VOTING of all things? LOL! JUSTICE for democracy and the EU at last! Spread the word folks, the system strikes back and stability of democracy is put first in Spain! Just as well millions are marching against Brexit and FOR the glorious neo Roman Empire, the EU!

If > both can cause harm, what's the difference you're highlighting? To be ethical in the process of airing an accusation, any accusation, the accusation must provide an actual fact, and a clearly stated position in relation to that fact. This foundation provides an opportunity to the accused to respond (in whatever forum the accuser chose). Without both the fact in issue, and the position held by the accuser in relation to that fact, the accused is provided no opportunity to properly respond, possibly no opportunity to meaningfully respond at all. I have not yet seen any fact by anyone posting here at lwn.net or elsewhere (yourself included), which substantiates the "hollering" and "justification opinions" for RMS to resign (to have already resigned) from the FSF. All I have seen are opinions, innuendo, and hearsay. The claim that opinions, innuendo and/or hearsay are sufficient "evidence" or "cause" to "metaphorically crucify" an individual in the public (or any other) sphere of human interaction, is a call not founded in ethics but instead is founded in evil - is opposed to our lives. Such a call is a call for mob rule, a "witch hunt" abdicating due process and abdicating our responsibility to one another as human beings. Those who understand (let alone value) justice and righteousness, understand these very basic principles. Taking justice a step further, an accuser, per Matthew 18, is advised to go speak with the accused ("your brother") in the first instance, that he might hear you, and if he does not hear you, go with some number of witnesses, that the accused's response may be witnessed by a number of others. Such processes as are (very) summarised above under the banner "due process", provide for the opportunity (still yet no certainty) for the accused and the accuser to come to an understanding and possible resolution. The mob witch hunt provides almost no such opportunity, just a forum for heedens heeding the rumours of those who rumour mongor without facts, to join in their force of numbers and crucify a probably good man in the name of any flippant emotional weakness in some rando snowflake accuser.

Posted Oct 14, 2019 3:05 UTC (Mon) by zenaan (subscriber, #3778) > "it" happened to me What I have heard by reading a first hand account: Apparently RMS asked an 18 year old woman on a date. Apparently she was uncomfortable about that. This took all of 10 or 15 seconds, and RMS never went near that topic with her again after that. And now RMS has been lynched from MIT and the FSF which he founded. When I used the phrase "All I have seen are opinions, innuendo, and hearsay", we need to add the words "and no facts which in my eyes justify the public lynching to have RMS removed from his positions at MIT and the FSF which he founded." I thought that was obvious at the time I wrote the words, but in hindsight I can see how the point needs to be clarified. Hopefully this is sufficient clarification.

So name the damn rule that RMS is not allowed to break! And be VERY PRECISE and CLEAR in your terminology, so that these older "bastards of the community" don't fall foul of the mob when they ask a woman younger than they are, on a date! Also, be damn clear about whether it is only RMS who is not allowed to ask women younger than "say, 30 years old" on a date, or whether it is "all men over the age of, say 40 years old" - or whatever the hell you rule is that JUSTIFIES THIS PUBLIC LYNCHING OF Richard Stallman, founder of the FSF and GNU! FFS folks appear so intellectually fraudulent and disingenuous at the moment. BY ALL MEANS tear one or another pathetic minor detail (in what I've written) to shreds, BUT AT LEAST HAVE THE DECENCY to address the core issue, and do so in a way which RMS, myself, and all other white men in this world can grasp YOUR POSITION so that YOUR RULES are not broken and so that YOU HEREAFTER REFRAIN from justifying these public lynchings. I expect more from you "Cyberax"! Is this the effing world YOU want to live in?!!

National Conservation Commission: USA's oil supply "will be entirely used within 25 or 30 years" at present rates

"an alarming report that the national supply of oil will be entirely used by within just 25 or 30 years more at the rate that the country is currently burning through the precious and decidedly finite fuel source" The Cheapest Oil Ever Sold https://www.zerohedge.com/energy/cheapest-oil-ever-sold https://oilprice.com/Energy/Oil-Prices/The-Cheapest-Oil-Ever-Sold.html An elite government-appointed group called the National Conservation Commission is charged with taking a comprehensive inventory of natural resources in the United States and discover where resources are being inefficiently handled and even squandered. They come back to the United States Congress with an alarming report that the national supply of oil will be entirely used by within just 25 or 30 years more at the rate that the country is currently burning through the precious and decidedly finite fuel source. The year is 1909. [That said, oil alarmists are still going strong today. ... lots of interesting history tidbits in article.]
