dm-crypt+LUKS
by Jose Damico 21 Jun '14

21 Jun '14

Hey people, Could you give me your impressions about the use (only in Linux) of dm-crypt + LUKS instead of truecrypt? For me there is no need to use my encrypted disks with OSX or Windows, so, due the last movements of truecrypt, I am planning to move my encrypted disks from truecrypt to dm-crypt + LUKS. Did you see is as a bad decision, in terms of possible flaws in dm-crypt? Best Regards yap

I meant as answer 'estimates on how big' question. Take what we know about storage, figure in some good efficiencies for the 'storage only' case. And figure what can be bought and operated year on year per foot. You could hide/support $1B + $1B/year but $10B/yr would be hard given entire intel budget is $80B, or $50+B if you drop mil. So... 1) How big can you get within budget? 2) What can you do with it re: a) crypto, or b) otherwise? https://en.wikipedia.org/wiki/United_States_intelligence_budget https://en.wikipedia.org/wiki/United_States_Intelligence_Community http://www.martingrandjean.ch/data-visualization-top-secret-us-intelligence…

And as in the design papers/blogs, Oracle ZFS seems to have some data that is not encrypted that arguably should be. https://blogs.oracle.com/darren/entry/zfs_encryption_what_is_on > And let me state for people wondering, "Why isn't it in OpenZFS already?" In the OpenZFS world, you deploy each OS's FDE underneath ZFS. OpenZFS will likely add native encryption feature flag someday to satiate those who want per dataset keying, etc... but, thanks to Oracle, anything post zfs28/zpool5 might not end up interoperating. https://en.wikipedia.org/wiki/ZFS http://www.open-zfs.org/

Re: Assange

Virtually nobody is not exploiting Assange for their own purposes. Kristinn Hrafnsson is among the media monsters, pro and con, creating and feeding a market for their derivative shallowness of Assange's fame. Our latest derivative exploitation over eight years: http://cryptome.org/2014/06/saluations-assange.htm To be sure, Assange has derivatively exploited Cypherpunks since about 1995, naming a book, articles, talks, brags, after this collective as if his own. That ownership, to be certain, is a given of this list as it should be everywhere to combat the thieves and spies of content, branded, marked up and marketed by way of centralizing media monstrosities. Combat between cryptoarchists of centralized control and cryptoanarchists of distributed uncontrol wll go on forever. Assange's fame and infame are being fought over by centralizers and decentralzers. Which way he will tip is his secret of controlling the tusslers as well as what he whispers to those he is fucking.

I’m not sure if that 2^88) is in bits or AES blocks, but let’s assume bits. Facebook is said to store about 2^62 bits, so we are looking at something 2^26 times larger than Facebook’s data storage. 8 rounds, lot more to go. >> I know this one organization that seems to be building an omnious observation storage facility, > > Any (reliable) estimates on how big? I believe the square footage is public, if not guesstimate by parking spaces etc in JYA's sat photos. Then fill it to the brim with nothing but 6TB drives, less some space for racks, aisles, power, network at say 50% better density than industry best [1]. That's your physical upper bound. $10M in drives at consumer pricing will get you a raw 177PB, or 236PB at double the space and power. Or $1B for 17EB. Budget is an issue. Give it a shot on paper, best estimate wins... [1] If all you care about is storage, you plug drives into tiny custom storage fabric asics and present giant block devices at the end of each row or room, not into bulky servers. Commodity CPU's have 64bit address space, ZFS covers that. Or go custom access/compute on your data as well. http://en.wikipedia.org/wiki/ZFS#Capacity

Ars Thecnica TrueCrypt Disinformation Article ???
by Jose Damico 20 Jun '14

20 Jun '14

This article from Ars (http://arstechnica.com/security/2014/06/following-truecrypts-bombshell-advi…) ****** Following TrueCrypt’s bombshell advisory, developer says fork is “impossible” TrueCrypt developer withholds permission, suggests "starting from scratch." ****** Seems to be a text inserted by some Intelligence Agency, as part of a disinformation agenda, with the aim of sowing fear in those who has interest in fork TrueCrypt. For me, there are no real facts demonstrated in the article. Also at end of the day, some organization or institution must claim the ownership of truecrypt in order to protect its interests over the source code. Am I right? What do you think? yap

Hey guys, This is my first post at cypherpunks... I'm new to the field of crypto and have done only some basic crypto work.I was wondering if you could provide me some papers on crypto and network security ... I'm working on developing secure embedded devices this summer
