Researchers Propose a Revocable Identity-Based Encryption Scheme
jd writes Identity-based public key encryption works on the idea of using something well-known (like an e-mail address) as the public key and having a private key generator do some wibbly-wobbly timey-wimey stuff to generate a secure private key out if it. A private key I can understand, secure is another matter. In fact, the paper notes that security has been a big hassle in IBE-type encryption, as has revocation of keys. The authors claim, however, that they have accomplished both. Which implies the public key can't be an arbitrary string like an e-mail, since presumably you would still want messages going to said e-mail address, otherwise why bother revoking when you could just change address? Anyways, this is not the only cool new crypto concept in town, but it is certainly one of the most intriguing as it would be a very simple platform for building mostly-transparent encryption into typical consumer apps. If it works as advertised. I present it to Slashdot readers to engender discussion on the method, RIBE in general and whether (in light of what's known) default strong encryption for everything is something users should just get whether they like it or not.

Bad Science And Scary Science

Spectroscopy Now For the Everyman
For those who don’t know, I have a bit of a side hobby fixing and using radiation detection equipment, such as Geiger counters.   If you’re not into amateur science and nuclear science/energy, this may not seem very exciting. Geiger counters and other basic radiation detectors are great for getting a general idea what the background […]
Anti-Vaxers Now Against All Life-Saving Injections
Vitamin K shots have been a mainstay of care for newborns for some time. 0.5 to 1.0 mg vitamin K1 is administered to newborns shortly after birth in the US and similar standards exist in most industrial countries. The occurrence of vitamin K deficiencies in newborns and bleeding problems associated with it has been estimated […]
Raw Milk Is Making People Sick
Milk: in western society it’s one of the most basic foods.  It usually comes from cows, but sometimes goats.   It also has a history of not always being safe to drink.   That’s because milk happens to be a good growth medium for bacteria.  The bacteria can get into the milk any number of ways.  It […]
25 Reasons not to vaccinate your children
 Thinking Of Vaccinating your Kids?   Think again.   I’d like to give you some reasons not to <sarcasm> 1.  You had to go through being sick with Chicken Pox, Measles and other painful and unpleasant conditions.  Why should your kids get off?   Does it seem fair that they don’t suffer when those before did?  I think […]
Recomended Facebook Groups and Pages
I have not always been a big social media fan, but I have to admit that Facebook is pretty great for keeping in touch with people and for finding groups of similar interests. There are some great Facebook pages and groups that are anti-bad science.  Many of these are funny and all are worth checking […]
Gas Turbines in Cars: The seemingly promising engine that never was
Today nearly all cars are powered with a conventional, reciprocating internal combustion engine. In such an engine, pistons (usually at least four) move up and down and are connected to a crank shaft that translates this into rotational motion.  As they move up and down, fuel vapor enters the combustion chamber and is ignited by […]
Students Make Film About Vaccines – Get Harrassment
It’s always nice to see young people with a passion for science, reality, skepticism and advocacy.   In Carlsbad, CA, a group of highschool students in a journalism class made a film about vaccines and vaccine denialism.  (It’s on the correct side of it) Via NBC San Diego More than a dozen current and former Carlsbad […]
One in Three Americans Implanted with RFID’s? Not really
First, a basic primer on what RFID’s are: An RFID is a small computer chip which holds a very small amount of information, typically just a string of numbers, letters or other symbols.  The chip has a tiny radio transmitter in it, and when a reader is brought near it, it will broadcast that data […]
New and Revolutionary Perpetual Motion/Free Energy Machine!
Watch the whole thing before commenting… Click here if your browser does not support embedded video They do a great job of making the first part seem like a real perpetual motion claim. I found it pretty damn funny, especially the very end. The sad thing is it makes as much senses as most free […]
It had to happen: The Ebola Conspiracy Theories
It happens periodically:  Ebola, a highly contagious and very deadly virus with horrific symptoms known as “flesh eating” has flared up in Africa.   This recent outbreak has been especially bad.   The virus is native to Africa and appears to survive in natural reservoirs such as bats or gorillas.  Periodically, it makes the jump to humans […]
