the new issue of scientific american features articles on encryption and hacking. one is by Phil Zimmermann, on public key cryptography. A policy article by Rivest (of RSA) argues against encryption restrictions in the US. a long article on internet hacking and breaking and entering describes the basic process that hackers use. Rivest uses the analogy of "gloves" for encryption, in the sense that we shouldn't outlaw gloves because the govt needs always to obtain fingerprints for identification. furthermore, "key escrow" is like gluing fingerprint copies to the bottoms of gloves, another waste of time.
