[Pasig-discuss] Long-Term Preservation and Encryption / POTSHARDS

[Thorsten Lange]

Hi Arvind,

actually, I have no idea how anonymization could be done in my case. It's 
a few hundred terabytes, and it's company data. E-mails and that stuff. 
I'm afraid I'm not around in the anonymization league for now.

Hi Thorsten,

Have you looked at data anonymization as an alternative to encryption in 
some scenarios, I have used it in small scale on projects and it seems to 
work for smaller and simple datasets but would like to hear more about 
this technique from tools and research perspective.

Thanks
Arvind

Dear Archivers, 

I'm investigating in options to secure sensitive content in the public 
cloud. I'm looking for a good paper that shows all the issues when 
encrypting data for the long term. (Encryption algorythm weakening, 
migration, key loss, key management and migration, etc). I found some 
stuff with Google, but if someone has something really convincing, I 
appreciate a link. 

Second, I found POTSHARDS as a really interesting option.

It's some years ago, and I haven't found if it got picked up somewhere and 
developed any further. 
Did anyone deal with this solution, know of someone who does, or follows a 
similar approach? 

Contact to the fellows from UC Santa Cruz? 
That would be an interesting topic for a next PASIC!
