<pre style="font-family: arial,sans-serif;"><font size="2">(...) it's factually inaccurate and thus<br>easily debunked. As for the Patterson paper, I'll be posting my thoughts over the next few<br>days, but generally find it uninteresting and academically sloppy flamebait.</font></pre>
</blockquote><br>I'm not an expert in Bitfrost at all, but in the event of a natural catastrophy, I think the Bitfrost keys can be updated using one $5 USB stick and distributing the keys to all the other laptops using Mesh networking.<br>
<br>Criticizing Libya, Nigeria and Thailand for being anti free-speech is irrelevant. Just because China has some human rights abuse problems, and the chinese firewall, blogger and yahoo mail dissidents in jail, does that mean that the 200 million chinese people who have access to the Internet is a bad thing? That's just wrong. OLPC is a trojan horse to bring knoledge and democracy to those countries. It doesn't really matter what curriculum the governments are going to pre-load on the laptops, or if they are going to try and filter the Internet access, people always figure out to use the Internet for what they want. And if a government wants to mass-disable laptops using Bitfrost, just get any amount of activating keys smuggled into the country using a $5 USB key and those laptops are reactived.<br>

I did not read the paper yet, but it seems interesting:<br>

A summary: In this paper, we discuss Bitfrost, the security model<br>
developed by the One Laptop Per Child project for its XO laptop<br>
computers. Bitfrost implements a number of security measures intended<br>
primarily to deter theft and malware, but which also introduce severe<br>
threats to data security and individual privacy. We describe several<br>
of the technical provisions in Bitfrost, outline the risks they<br>
enable, and consider their legal ramifications and the psychological<br>
impact posed for children and society.<br>
