Vanishing Act

The NYTimes article on reports on the work of University of Washington computer scientists on "self-destructing messages."

Vanish uses a key-based encryption system in a different way, making it possible for a decrypted message to be automatically re-encrypted at a specified point in the future without fear that a third party will be able to gain access to the key needed to read the message.

The pieces of the key, small numbers, tend to “erode” over time as they gradually fall out of use. To make keys erode, or timeout, Vanish takes advantage of the structure of a peer-to-peer file system. Such networks are based on millions of personal computers whose Internet addresses change as they come and go from the network. This would make it exceedingly difficult for an eavesdropper or spy to reassemble the pieces of the key because the key is never held in a single location. The Vanish technology is applicable to more than just e-mail or other electronic messages. Tadayoshi Kohno, a University of Washington assistant professor who is one of Vanish’s designers, said Vanish makes it possible to control the “lifetime” of any type of data stored in the cloud, including information on Facebook, Google documents or blogs. In addition to Mr. Kohno, the authors of the paper, "Vanish: Increasing Data Privacy with Self-Destructing Data," include Roxana Geambasu, Amit A. Levy and Henry M. Levy.

In a posting on Dave Farber's Interesting Persons list, Ed Garek observes:

Congratulations on the NYT article. However, the significant point of using a trust model that does not depend on the integrity of third parties is not new, while relying on a peer-to-peer network for "key hiding" is by itself an unsolved problem today (both technically and commercially). The free "Zmail Basic" listed in "Ten Free Services To Send Self-Destructing Emails Which Expire/Disappear Automatically After Specified Time Interval" ... also uses a trust model that does not depend on the integrity of third parties but the novelty there is that keys are not stored anywhere (each dialogue party holds a part of it), and uses a system of "minority control" to allow independent destruction of the capability to reassemble the entire key.

The BD+ Cat and Mouse Game: Advantage BD+

The programmable security technology used by Fox and more recently Paramount to protect theatrically released films on Blu-ray discs represents an important step forward over previous security technologies, such as the quickly broken CSS for DVDs and AACS encryption key management used on the now dead HD-DVD and on Blu-ray. Although no security technology is perfect, BD+ is an important advance because the programming can be modified in response to successfull cracks. 

There has always been a cat and mouse game between security technologies of all kinds and those who seek to break them. Each side learns from the others successes and failures and improves their defense and offense accordingly. Postings on Slashdot  and the Slysoft website report that there are now at least 19 Blu-ray releases that have not yet been broken.

It appears that the least powerful forms of BD+ were used first in order to determine how crackers / hackers would attack the security system. Having been through several iterations, it seems that the level of security has been upgraded on the newer offerings.
