Hedge 171: Paul Grubb on Zero Knowledge Middleboxes
Middleboxes are used in modern networking to sniff out attack traffic (IDS), block unwanted traffic (stateful packet filters), and share load among several different servers. Encryption, however, is making it hard for the middleboxes to do their job. Paul Grubb joins Tom Ammon and Russ White to discuss zero knowledge middle boxes, which allow operators to enforce arbitrary policies on the underlying traffic of an encrypted connection without decrypting it.
Hedge 170: AI in the Real World with Jonathan Bartlett
Artificial Intelligence is being heavily hyped right now, especially in light of the newer generative AI systems (like ChapGPT). What is the reality behind the hype? Jonathan Bartlett, fellow at the Discovery Institute, joins us for a discussion on AI reality for this episode of the Hedge.
Hedge 169: Network Address Translation with Steinn
Network Address translation is one of those phrases that strikes fear into the hearts of some network engineers … and joy into the hearts of others! Steinn Bjarnarson joins us to discuss the history of NAT, its uses, its misuses, and how NAT fits into the big picture of network design today. Steinn just finished writing a paper on the history of NAT.
Hedge 168: Roundtable
It’s roundtable time! In February’s roundtable, Eyvonne joins Tom and Russ to talk about Network as a Service, innovation, and marketing. Then we jump into the topic of the year at this point—ChaptGPT. Finally, we talk about proposals to eliminate noncompete agreements in the United States. What would this mean? Would it be better for tech, or worse?
As always, you can listen to the show on just about any podcatcher, you can listen right here, or you can download the show to listen later.
Hedge 167: Oblivious DoH with Chris Wood
DNS over HTTPS, or DoH, is designed to protect the end user’s DNS queries from last mile providers—but recursive servers (or resolvers) also have full access to what a user is asking for. How can users preserve their privacy against data collection at recursive servers? ODoH provides one answer. Listen in as Tom Ammon, Chris Wood, and Russ White discuss how ODoH works, and what this means for user privacy.
Hedge 166: Christopher Wood and masque
This week, Chris joins us again to talk about Multiplexed Application Substrate over QUIC Encryption, or masque, which is a more generalized privacy proxy. You can find more about masque at the IETF WG page.
