The Word example actually has other worrying problems not mentioned. A Word document contains a lot of hidden information, including other versions. It would be quite easy to sign a Word document that, when you viewed it, looks significantly different then it could be displayed without violating the signature. This is due to numerous problems, the most basic of which is that we often don't sign what we view but instead some binary that we _believe_ represents what we viewed but often does not. This is not just theoretical nor esoteric, but quite easy as the Word example shows. In effect we have absolutely no idea what we are signing most of the time even without comprimise of keys, programs and all that good stuff. > -----Original Message----- > From: owner-cryptography(a)c2.net [mailto:owner-cryptography@c2.net]On > Behalf Of R.

[liberationtech] TeliaSonera and Azerbaijan, Belarus and Uzbekistan
by Bernard Tyers - ei8fdb 06 Jul '18

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Some wonderful quotes from Mr. Nyberg: "the company itself could not solve the underlying problem that undemocratic governments could abuse their legal right to access and shut down telecoms networks" "We need help from national and international organisations whether that be the UN, EU, (or) NGOs if we are going to make any significant impact on human rights" "If we experience a situation where under a certain government there are serious breaches of human rights on a regular basis ... we must be ready to have a debate in the company whether we should be in that country or not" Telecoms firm TeliaSonera to focus more on human rights http://uk.reuters.com/article/2012/08/23/uk-telia-responsibility-idUKBRE87M… (Reuters) - TeliaSonera (TLSN.ST), burnt by charges it cooperated with authoritarian governments, said on Thursday it would focus more on human rights issues where it operates and is eying Myanmar as a possible target for expansion. The Nordic and emerging markets telecoms group, in which Sweden has a 37 percent stake, came under scathing criticism earlier this year for allowing authorities in Azerbaijan, Belarus and Uzbekistan to access its network to keep tabs on anti-government activists. CEO Lars Nyberg said Telia, which has businesses across central Asia as well as the Nordic and Baltic regions, would take measures to bolster the protection of freedom of expression and privacy. Requests from governments to close sites or networks would now be dealt with at board level not nationally, he said. Telia will also cooperate with 10 other companies - including Alcatel-Lucent (ALUA.PA), France Telecom (FTE.PA), Nokia Siemens Networks NOKI.UL Vodafone (VOD.L), AT&T (T.N) and Telefonica (TEF.MC) - to draw up rules on how telecoms firms implement the United Nation's guidelines for preserving privacy and freedom of expression. Although Telia is not considering withdrawing from any of the countries in which it operates and has management control, it would have to consider that possibility if the situation merited it, Nyberg said. "If we experience a situation where under a certain government there are serious breaches of human rights on a regular basis ... we must be ready to have a debate in the company whether we should be in that country or not," Nyberg said. Telia has been in hot water again in recent days after its daughter company in Tajikistan blocked news sites at the request of the government. Nyberg said the company itself could not solve the underlying problem that undemocratic governments could abuse their legal right to access and shut down telecoms networks. "We need help from national and international organisations whether that be the UN, EU, (or) NGOs if we are going to make any significant impact on human rights," he said. Telia said criticism of its actions in central Asia has not undermined the company in countries without full democracy and where telecoms markets are set to develop fast. Nyberg said that Telia was looking at the possibility of entering the market in Myanmar where, after decades of military rule, the government has introduced sweeping reforms, including allowing elections, easing rules on protests and censorship and freeing dissidents. Nyberg said the developments were such that Telia could now consider operating in the country, where the telecoms network for the country's 60 million people is barely developed. "Two years ago I would never have thought that we could even think about going into Myanmar," he said. "But what has happened in Myanmar over the last 18 months allows us to consider if we could do something in Myanmar."

Bad guys routinely control zombie farms of 100,000 machines or more. People I know who run a blacklist of spam sending zombies tell me they often see a million new zombies a day. This is the same reason that hashcash can't work on today's Internet -- the good guys have vastly less computational firepower than the bad guys. I also have my doubts about other issues, but this one is the killer.

LFScon will be a once-in-a-lifetime opportunity to hear Prometheus Award winners and LFS leaders explore the future of freedom and the potential of libertarian science fiction to shape a more rational, diverse, tolerant and optimistic vision of what is possible in the 21st and coming centuries. The Libertarian Futurist Society will present its 2001 Prometheus Hall of Fame awards ceremony before an audience of more than 1,500 people during the intermission of Marcon's Saturday night masquerade-- its most popular event. LFScon will feature more Prometheus Awardwinning novelists than any other sf convention or libertarian conference in history. So far, the LFS has confirmed eight Prometheus Awardwinners, who collectively have won 11 Best Novel awards and five Hall of Fame awards: special LFScon Guest of Honor L. Neil Smith (The Probability Broach, Pallas), Poul Anderson (Trader to the Stars, The Stars are Also Fire, The Star Fox), F. Paul Wilson (Healer, Wheels within Wheels, An Enemy of the State), James Hogan (Voyage From Yesteryear, The Multiplex Man), Vernor Vinge (Marooned in Realtime, A Deepness in the Sky), J. Neil Schulman (Alongside Night, The Rainbow Cadenza), Brad Linaweaver (Moon of Ice) and Victor Milan (The Cybernetic Samurai.)

As Ohio's oldest and largest sf/fantasy convention, Marcon annually attracts more than 3,000 people (3,400 last year), including authors, artists, editors, scientists, costumers, gamers and fans from more than 30 states and Canada. There's something for everyone, including autographing sessions (with all Prometheus Awardwinners); author readings; dances; parties (including an LFS Friday night bash in a Hyatt Hotel suite); art show & auction; charity auction; panel discussions on separate program tracks about literature, science, animation, art, children's programming and more; and a large dealer's room (with 120 tables, including a large Libertarian Futurist Society exhibit/book-sale.) Besides freedom, Marcon's other 2001 program themes will be intelligence (in honor of 2001: A Space Odyssey's and "2001" guest star Gary Lockwood) and heroic fantasy (in honor of Marcon fantasy guest Robert Jordan.) Other featured Marcon/LFScon guests include Babylon 5's actor Peter Woodward, libertarian sf authors Steven Burgauer ("The Grandfather Paradox,The Last American) and Joseph Martino (author of "Science Funding: Politics & Porkbarrel" and "Analog" short stories); First Amendment/Internet advocate Matt Gaylor; and LFS leaders Victoria Varga, Amy Rule, Chris Hibbert and Lynn Maners.

FC: FBI gets cash to spend on anti-encryption, broadband snooping
by Declan McCullagh 06 Jul '18

06 Jul '18

http://www.wired.com/news/print/0,1294,45632,00.html According to the report accompanying a spending bill that's awaiting a floor vote in the Senate: * The FBI will receive an extra $7 million for technology to thwart encryption. The appropriations committee intends for it to be spent on: "(1) analysis/exploitation of systems to allow access to data pre-encryption, (2) recognition/decryption of data hidden in plain sight, and (3) decryption of encrypted data." * Another $7 million goes to a plan to improve "intercept capabilities." The fed-speak for this is "developing broadband capabilities, and procuring prototypes capable of intercepting transmissions outside of the FBI's technical reach." Translation: Create better ways to eavesdrop on cable modems and DSL connections. * Antitrust enforcement gets a boost. The division, best known recently for its dogged pursuit of Microsoft, receives $3.6 million extra, but $10 million less than the Bush administration requested. The committee predicts a slew of mergers because of "the collapse of high technology stocks, and the resultant downward pressure on all stock prices." * Las Vegas, St. Louis, Charleston and Kansas City will split $6 million earmarked for gun surveillance technology. The plan is to spend it on acoustic sensors scattered around downtown areas so the location of a gunshot can be triangulated and located. ------------------------------------------------------------------------- POLITECH -- Declan McCullagh's politics and technology mailing list You may redistribute this message freely if you include this notice.

Outlaw Biology Symposium and Faire, UCLA, Jan 29-30, Call for Ideas
by Christopher Kelty 06 Jul '18

06 Jul '18

Dear DIYers: UCLA's Center for Society and Genetics (http://socgen.ucla.edu) is organizing a symposium (Jan. 29-30, 2010) which I've given the tentative title of "Outlaw Biology" ("when e. coli is outlawed, only outlaws will have e. coli" etc.). The symposium's confirmed participants are: Meredith Patterson (hacker, writer, maker of yogurt and other technologies), Roger Brent (Fred Hutchison Cancer Center, Seattle), Gaymon Bennett (SynBERC, UC Berkeley), Paul Rothemund (maker of DNA Origami, CalTech), Hugh Rienhoff (Mydaughtersdna.org) and Jason Bobe (DIYBio, Church Lab, Harvard). Victorian Vesna, bioartist and faculty member of of UCLA's Digital Arts and Media dept. will likely participate and I will moderate. I'm excited about that lineup, and will send more details to the list as things settle. What I'm most excited about though is the hackfest/biofaire planned for the saturday after the symposium (Jan 30). It will be held on UCLA's campus and open to anyone. Jason has agreed to bring bioweathermaps (and make use of the Arboretum on campus, rich source of diversity that it is), Paul has agreed to do some aspect of DNA synthesis, either the design part of the visualization part, and Meredith has agreed to do something as yet unspecified (but awesome). So I'm writing to open this up to the list and invite participation from anyone who wants to come, do a demonstration, a teach-in, a DIY happening, etc. There are no official funds to bring people here or fund these things, unfortunately, but depending on what people might want to do, there is the possibility of finding in-kind support on campus (e.g. equipment or materials). Obviously it will be easiest for people in SoCal to come to this, but I'd love it if others were able to make it as well. If you think you'd like to be part of this, and have an idea for what to do, please send a brief abstract to me (or to the list if you want to recruit others). I'm open to anything, but I don't yet know how much space we will have, or how many people we can accomodate. ck --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "DIYbio" group.
