privacy in numbers?

 

One of the interesting things about Skype is that the Luxembourg based company provides encrypted communications to all Skype to Skype users. (See summary here).

“Skype uses AES (Advanced Encryption Standard)—also known as Rijndel—which is also used by U.S. government organizations to protect sensitive information. Skype uses 256-bit encryption, which has a total of 1.1 x 1077 possible keys, in order to actively encrypt the data in each Skype call or instant message.” The point of all this mumbo-jumbo is that Skype uses an encryption algorithm* known as 256-bit AES. The National Institute of Science and Technology states that it would take a computer using present-day technology “approximately 149 thousand-billion (149 trillion) years to crack a 128-bit AES key.” And that’s for the 128-bit version; Skype uses the more “secure” 256-bit standard. Since computers have a way of quickly getting more powerful, the institute forecasts that “AES has the potential to remain secure well beyond twenty years.”

They used to say “there’s safety in numbers”, I suppose in the future it’ll be “privacy in numbers”

(p.s. How do you use Skype? See youtube here.)
