Hedge 171: Paul Grubb on Zero Knowledge Middleboxes

By Russ | 24 March 2023 | Comments Off on 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 167: Oblivious DoH with Chris Wood

By Russ | 22 February 2023 | Comments Off on 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.
