Network challenges: Naming and Authentication

Protagonista: Radia Perlman
Año: 2024
País: Argentina
Género: Terror
Track: Security
Idioma: Inglés

The world has developed terrific cryptographic algorithms, and all sorts of wonderful protocols. However, as this talk shows, there are many challenges that people don't seem to worry about, that make network communication inconvenient and insecure. This talk will describe as many examples of this as possible, given the time constraints. Also, the talk will describe an example of something people propose as a "solution" ("distributed identities using blockchain"), and argue that it does not solve any of the challenges we'll discuss, and does not even do as good a job as the current Internet.

Sobre Radia Perlman

Radia Perlman

Fellow at Dell Technologies

Radia Perlman developed the technology for making network routing self-stabilizing, largely self-managing, and scalable. She also invented the spanning tree algorithm, which transformed Ethernet from a technology that supported a few hundred nodes within a single building, to something that could support large networks. The specific routing protocol she designed (IS-IS) is still widely deployed, and the concepts have been copied into other link state protocols such as OSPF. Her spanning tree protocol also continues to be widely deployed, and is the technology behind modern-day Ethernet. She also has made contributions in network security. She is the author of the textbook “Interconnections” (about network layers 2 and 3) and coauthor of “Network Security: Private Communication in a Public World” (3rd edition published last year, about cryptography, quantum computing, quantum-safe public key algorithms, and more). She has taught as adjunct faculty at various universities including MIT, Harvard, Texas A&M, and University of Washington. She has a PhD in computer science from MIT. She has been inducted into the Inventor Hall of Fame, the Internet Hall of Fame, and the US National Academy of Engineering.
