Hedge 285: Post Quantum Crypto

Is quantum really an immediate and dangerous threat to current cryptography systems, or are we pushing to hastily adopt new technologies we won’t necessarily need for a few more years? Should we allow the quantum pie to bake a few more years before slicing a piece and digging in? George Michaelson joins Russ and Tom to discuss.

Hedge 284: Netops and Corporate Culture

We all know netops, NRE, and devops can increase productivity, increase Mean Time Between Mistakes (MTBM), and decrease MTTR–but how do we deploy and use these tools? We often think of the technical hurdles you face in their deployment, but most of the blockers are actually cultural. Chris Grundemann, Eyvonne, Russ, and Tom discuss the cultural issues with deploying netops on this episode of the Hedge.

The ease with which those images and videos traveled, the thoughtless way in which we shared them, reveals the sinister side of technological advancement. It exposes the degree to which social media has desensitized us, stripped us of the natural horror that ought to accompany the spectacle of death, and conditioned us to consume human suffering as one more item in an endless buffet of digital content.


It’s normal for post-quantum cryptography to be rolled out as an extra layer of security on top of traditional pre-quantum cryptography, rather than as a replacement.


Not that many years ago, telephone and broadband networks were structured in such a way that most outages were local events. A fiber cut might kill service to a neighborhood; an electronics failure might kill service to a larger area, but for the most part, outages were contained within a discrete and local area.


Far from a future concern, AI is already the single largest uncontrolled channel for corporate data exfiltration—bigger than shadow SaaS or unmanaged file sharing.

A number of recent changes have helped to push Ethernet forward, advancing its capabilities to better meet the needs of AI.


Cloudflare has confessed to a coding error using a React useEffect hook, notorious for being problematic if not handled carefully, that caused an outage for the platform’s dashboard and many of its APIs.


Working with MikroTik and IP Infusion’s OcNOS to interop EVPN/VxLAN has been on my wish list for a long time.


Have you heard about MRT dumps, but never tried to use them because the bar seems too high? Or are you tired of doing “parse -> grep -> process” every time you touch BGP MRT dumps?


Unfortunately, history is again being rewritten. It is rapidly becoming clear that LLMs are not economical.


As part of our research into post-quantum cryptography (PQC) for DNSSEC, we test PQC as a drop-in replacement for classical algorithms. We explore a transition where both run simultaneously, analysing how resolvers validate records, edge cases, and the feasibility and impact of such a period.


In much of the world, we are in an era that I like to call the “post-gigabit era”. Many users have access to gigabit connections—or at least hundreds of Continue reading

Hedge 283: Technical Planning

We network engineers often find ourselves without a viable plan–our plans always seem to go awry, to the point that many network engineers just give up on planning. Is “giving up” the right solution? Or can we learn to be better planners? Jonathan Adams and Tim McConnaughy join Russ to discussion planning for network engineers.

“Classic” TCP uses an extremely simple loss-based congestion detection algorithm that is intended to save networks from collapsing under extreme overload.


The endgame is a society where corporate algorithms make decisions about employment, education, and social interaction with no accountability.


The rise of Agentic AI, the emergence and adoption of AI agents and agent-to-agent networking to autonomously perform tasks on behalf of humans, has introduced unique challenges for existing security products.


In the landscape of organizational management, a distinction exists between teams that (a.) efficiently deliver a high-quality service or product, and (b.) those that innovate and develop their thought leadership in an area of emerging technology.


Broadcom CEO Hock Tan delivered a rather defiant keynote to open the VMware Explore conference in Las Vegas recently, telling the audience they are better off using the latest version of VMware Cloud Foundation (VCF) on-premises than hyperscale cloud service providers.


The public is told that AI systems are super smart and have the world’s info at their electronic beck and call. At the same time, it is humans and human organizations who claim professional expertise and so deliver their “truth” via media and Internet.

Can we trust AI? Will AI take our jobs? Is an AI app safe? Shall we invest in AI company? Create an AI startup? Will AI accelerate cybercrime?


This study highlights the inadequacy of current privacy protection measures and proposes an automated, sustainable approach to correlate user profiles, including homonyms and pseudonyms, solely through publicly available data.


Bargury’s attack starts with a poisoned document, which is shared to a potential victim’s Google Drive. (Bargury says a victim could have also uploaded a compromised file to their own account.)

The current state of digital identity is a mess. Your personal information is scattered across hundreds of locations: social media companies, IoT companies, government agencies, websites you have accounts on, and data brokers you’ve never heard of.


It turns out that, if you have your domain hosted by a big provider (we happen to use GoDaddy), it’s easy to turn on DNSSEC. But I think it says a lot that it took us this long (and the stimulus of working on a new security book) to get us to turn on DNSSEC


As we left the laboratory, I thought about how we in the computing field build a tremendous number of things that really cannot be called beautiful and then are commonly tossed aside without a thought.


The accelerated migration to advanced services will be accompanied by unprecedented complexity, and security and reliability concerns that must be addressed by the network-engineering and formal-methods communities.


Quantum scientists have long treated quantum entanglement as precious cargo, forging fresh links for every secure message or computation. A new theoretical study proposes a thriftier route, letting an existing pair pass portions of its entanglement down an extended chain.

Fast Following Fails

Fast following fails.

Whenever I hear a leader in a technology business say, “We’re going to fast follow because it’s the most profitable place to be,” I know I’m looking at a failed organization. I didn’t come to this conclusion by thinking about it. I came to this conclusion by observing it repeatedly.

After observing it, however, I wanted to understand why this particular strategy fails so consistently and spectacularly. Why? To understand my theory, we need to start in a somewhat different place than business—we need to start with the nature of goals and humans.

You can place goals into two buckets: first things and second things.

First things are foundational. If you are a technology company, the first thing is building a stable, resilient, and flexible platform (or foundation). The products you sell will only be as stable as your platform. The innovation you achieve will only be as consistent as your platform is.

Second things are goals you can only achieve once you’ve built the first things.

Here’s the hard truth no one wants to hear: Generating revenue is a second thing.

Humans become what they do.

We all want to believe we can become what we Continue reading
