Schneier and Kerr on Encryption Workarounds

By John Levine
John Levine

Bruce Schneier is a famous cryptography expert and Orin Kerr a famous cyberlaw professor. Together they've published a law journal article on Encryption Workarounds. It's intended for lawyers so it's quite accessible to non-technical readers.

The article starts with a summary of how encryption works, and then goes through six workarounds to get the text of an encrypted message:

It then draws some lessons, starting with the obvious one that no workaround works all the time but they all work some of the time, and then considers the often ambiguous legal status of workarounds.

It's well worth reading for anyone interested in the contentious intersection of law and cryptography.
