Just as 2000 was a rough year for firewalls, with holes blown in both commercial and open-source products, 2001 was a most uncomfortable year for the secure shell, or ssh. Several groups focused their attentions on this cornerstone of the net, and several problems emerged. ssh has emerged from this scrutiny a stronger product. . . .

Quantum crypto edges closer

British boffins have made a breakthrough in quantum cryptography, an advanced code-making technology which is theoretically uncrackable, by developing a single photon-emitting diode. The researchers from the University of Cambridge and Toshiba have discovered a way of incorporating semiconductor nano-technology into . . .

Casual PKI and making e-mail encryption easy

E-mail encryption seems to be hard enough, or annoying enough, that even many technically sophisticated people don't do it regularly. Non-technical people rarely seem to be able to figure it out at all. Even though we have a great free implementation . . .

IPsec Tunneling Between FreeBSD Hosts

IPsec is short for IP security, which is a manner of encrypting and authenticating Internet traffic all the way down to the IP packet level. That means that protocols such as SMTP, which are inherently insecure, can be reliably secured. Inherent to IPv6, IPSec is somewhat bolted onto the side of IPv4. But it works, and it works very well.. . .

Tim May: Rumors of the death of Cypherpunks are greatly exaggerated

Over the course of the last week or so a number of news sites reported the demise of the cyperpunks mailing list. Tim May writes that he thinks it's a matter of course for the lifecycle of a mailing list, and perhaps not as noteworthy as it's being made to be... "The article is not a bad one, and actually makes some good points. Predictably, the headline is lurid and derogatory.". . .
