I'm far from an expert on this, but I'm surprised that no one has pointed out: http://www.schneier.com/paper-secure-logs.html A classic paper on how to do just this. IIRC correctly, it describes a scheme to add a digest to each log record/line which includes the digest of the prior record/line. So, in order to tamper with a record you have to tamper with all the following records/lines as well. Security by induction ;) ~rmp

The First Evolving Hardware? 148

Masq666 writes "A Norwegian team has made the first piece of hardware that uses evolution to change its design at runtime to solve the problem at hand in the most effective way. By turning on and off its 'genes' it can change the way it works, and it can go through 20,000 - 30,000 generations in just a few seconds. That same number of generations took humans 800,000 - 900,000 years." The University of Oslo press release linked from the article came out a few days ago; the researchers published a paper (PDF) that seems to be on this same technology at a conference last summer.
