RSA Encryption Next: RSA Exercise Up: crypto Previous: Certification OK, in the previous section we described what is meant by a trap-door cipher, but how do you make one? One commonly used cipher of this form is called ``RSA Encryption'', where ``RSA'' are the initials of the three creators: ``Rivest, Shamir, and Adleman''. It is based on the following idea: Windows hack for Web-surfing privacy High performance access to file storage Those who read our article "Internet anonymity for Windows power users" know that I've been in quest of a way to assign the IE browser cache, cookies, typed URLs and history to RAM so they're never written to disk. Of course you can set your browser to delete the cache on exit, but there will be traces on the HDD; and you can block cookies or use a cookie management program, but blocking them makes surfing inconvenient, and cookie managers also leave traces on the HDD.

The Undiscovered Bedrooms of Manhattan A friend of mine once told me about the "typical dream of a New Yorker," as he described it, wherein a homeowner pushes aside some coats and sweaters in the upstairs closet... only to reveal a door, and, behind that, another room, and, beyond that, perhaps even a whole new wing secretly attached to the back of the house... Always fantasizing about having more space in Manhattan. And so I was thinking today that you could go around Manhattan with a microphone, asking people who have had that dream to describe it, recording all this, live, for the radio – or you ask people who have never had that dream simply to ad lib about what it might be like to discover another room, and you ask them to think about what kind of room they would most like to discover, tucked away inside a closet somewhere in their apartment.What additions to space do the people of New York secretly long for? (With thanks to Robert Krulwich, who puts up with emails from me full of ideas like this...).
Internet anonymity for Windows power users High performance access to file storage Our previous article, "Do-it-yourself Internet anonymity" was targeted towards average Windows users. It generated a startling number of e-mail requests for some advanced tactics, which I'm happy to supply. However, power user or not, I'd recommend at least skimming the earlier article if you haven't read it, just to ensure that you're not forgetting something obvious and useful. I'm not going to re-cap much of it here. Anonymous browsing DIY USB password generator » Code and Life Having done half a dozen V-USB tutorials I decided it’s time to whip up something cool. As USB keyboards were an area untouched, I decided to make a small USB HID keyboard device that types a password stored in EEPROM every time it’s attached. A new password can be generated just by tabbing CAPS LOCK a few times (4 times to start password regeneration and one tab for each password character generated, 10 is the default password length). Below you can see the device in action: The place I work at requires me to change my password every few months so this would be one way to skip remembering a new password altogether (as long as I remember to write it down before regenerating a new one so password can be changed :). What is inside?

NY Mummy Smugglers Reveal Vast Antiquities Black Market The rescue of an ancient Egyptian mummy's sarcophagus this month from alleged smugglers in New York — the first time authorities say an international artifacts' smuggling ring was dismantled within the United States — sounds more like the plot of a movie than reality. Amazingly, however, mummy smuggling not only still happens today, it was once so common that enough mummies were available to be ground up and sold as powder, archaeologists reveal. "Mummy powder was something you could buy in pharmacies up to 1920, because people thought it was a type of medication," said Egyptologist Regine Schulz, curator of ancient art at the Walters Art Museum in Baltimore. Today's black market for mummy and other antiquities is in the billions of dollars, though exact numbers aren't known.
How to Completely Anonymize Using Anomos How to Completely Mask & Anonymize Your BitTorrent Traffic Using Anomos A couple times a year, I hear about someone I know receiving that oh-so-scary letter from their ISP telling them to stop torrenting.

Your Privacy Kind of Sucks, Fix it Up This Weekend Since it's hard to trust what companies that get your data will do with it, the best way to maintain your privacy online is to minimize what you give them. Create accounts with pseudonyms or variants of your name (yes, even Facebook and Google+). Supply only profile information that is absolutely necessary, and lie about critical stuff like birthdates. Turn off all app- and ad-related functionality on Facebook and other sites wherever possible.
City Systems It would be far easier and would require less energy to build new, efficient cities than to attempt to update and solve the problems of the old ones. The Venus Project proposes a Research City that would use the most sophisticated available resources and construction techniques. Its geometrically elegant and efficient circular arrangement will be surrounded by, and incorporated into the city design, parks and lovely gardens. This city will be designed to operate with the minimum expenditure of energy using the cleanest technology available, which will be in harmony with nature to obtain the highest possible standard of living for everyone. This system facilitates efficient transportation for city residents, eliminating the need for automobiles.
Why Black Market Entrepreneurs Matter to the World Economy Soon, two-thirds of the world's workers will be part of street economies, Neuwirth says.Photo: Jessica Dimmock Not many people think of shantytowns, illegal street vendors, and unlicensed roadside hawkers as major economic players. But according to journalist Robert Neuwirth, that’s exactly what they’ve become. In his new book, Stealth of Nations: The Global Rise of the Informal Economy, Neuwirth points out that small, illegal, off-the-books businesses collectively account for trillions of dollars in commerce and employ fully half the world’s workers. Further, he says, these enterprises are critical sources of entrepreneurialism, innovation, and self-reliance.
