Post Quantum Security track with talks from Bas Westerban and Tirumaleswar Reddy.
Dawn of the Post Quantum Internet
We are at a pivotal moment in cybersecurity. Browsers are rolling out post-quantum encryption by default to counter the store-now-decrypt-later threat. What once was the subject of futuristic tech demos, will soon become the baseline expectation for security. Encryption is only half the story. Post-quantum certificates are much more challenging to deploy. In this talk, we will take measure of the current state, and the challenges that lay ahead for the public Web and its PKI.
PQC for Engineers
I will talk about the “Post-Quantum Cryptography for Engineers” draftthat is adopted in the PQUIP WG. This document explains why engineers need to be aware of and understand post-quantum cryptography. It emphasizes the potential impact of Cryptographically Relevant Quantum Computers on current cryptographic systems and the need to transition to post-quantum algorithms to ensure long-term security.

IPv6 track with talks from Davey Song and Tommy Pauly
In recent years, the global uptake of IPv6 has accelerated significantly. This presentation will offer insights into the large-scale deployment and practical implementation of IPv6 at Alibaba Group. As a leading case study, Alibaba’s experience exemplifies the IPv6 development within China.
Happy Eyeballs Version 3: Better Connectivity Using Concurrency
Many communication protocols operating over the modern Internet use hostnames. These often resolve to multiple IP addresses, each of which may have different performance and connectivity characteristics. Since specific addresses or address families (IPv4 or IPv6) may be blocked, broken, or sub-optimal on a network, clients that attempt multiple connections in parallel have a chance of establishing a connection more quickly. This presentation describes the requirements for algorithms that reduce this user-visible delay and provides an example algorithm, referred to as “Happy Eyeballs” over its various iterations.

Internet Technology and Governance with talks from Amrita Choudhury and Simone Basso
Intersection of Tech and Policy from Indian Perspective
We are living in a digital age where technology has become an integral part of our lives. While technology has transformed our lives by ushering in new opportunities, we are also witnessing new challenges, which regulators are grappling to address. To keep up with the times, even in India, we are witnessing several new regulations that have been brought in (such as the Digital Personal Data Protection Act. The Telecommunications Bill 2023) and discussions underway to overhaul or bring in new regulations (such as the Digital India Act, Digital Competition Bill, Broadcasting Services Bill 2023, Cybersecurity Strategy, etc.). Additionally, there are ongoing discourses to address the challenge of misinformation and fake news (deep fakes), governance of AI, discussions on network usage fees, encryption, etc.
The talk would highlight these regulatory changes and trends and why all stakeholders especially the technical community must participate in such discourses so that India can come up with nuanced, implementable robust, forward-looking regulations. The talk would also discuss how the technical community can engage meaningfully in these discourses.
How Internet censorship changed in Russia during the 1st year of military conflict in Ukraine
As of today, last year, Russia started its military operation in Ukraine. This was followed by increased levels of internet censorship, as Internet Service Providers (ISPs) in Russia started blocking access to several news media websites. In early March 2022, OONI published a report documenting these blocks, as well as the blocking of a site (200rf.com) that shares information about captured and killed Russian soldiers in Ukraine. OONI also reported that Russian ISPs started throttling access to Twitter on 26th February 2022, and switched to blocking it by 4th March 2022 – at which point, they also started blocking access to Facebook. Information controls are known to occur during conflicts, and the increased censorship events in Russia suggest an attempt to control the narrative surrounding the conflict in Ukraine. But has internet censorship changed in Russia over the last year? In this report, we attempt to answer this question through the analysis of OONI measurements collected from Russia between January 2022 to February 2023. We supplement our findings with information from relevant legal analysis and desk research provided by Roskomsvoboda.
Several widely-deployed messaging applications have developed their own protocols. While these protocols are similar, no two are close enough to interoperate. As a result, each application vendor has had to maintain their own protocol stack and independently build trust in the quality of the protocol. The goal of the
working group is to develop a standard messaging security protocol for human-to-human(s) communication with the above security and deployment properties so that applications can share code, and so that there can be shared validation of the protocol (as there has been with TLS 1.3).
Neighbour Discovery for IPv6 forms the cornerstone of efficient network communication in the IPv6 realm. It facilitates address resolution, duplicate address detection, and router discovery, making it indispensable for seamless communication across IPv6 networks. However, as enterprises migrate to IPv6, the conventional ND6 protocol may face challenges in terms of scalability and performance.
To address these limitations, our research focuses on incorporating the enhancements proposed for 6lowpan in RFC 6775 and 8505 into the mainstream ND6 protocol. These RFCs present innovative solutions that improve the speed and accuracy of neighbour discovery while optimizing the use of multicast messages.
In particular, RFC 6775 outlines mechanisms for optimizing ND6 for low-power and lossy networks (6Lowpan). By bringing these optimizations into the mainstream ND6, we aim to enhance its performance and adaptability, especially in enterprise settings.
Additionally, RFC 8505 proposes solutions to reduce unnecessary traffic and processing overhead in ND6, further optimizing its performance in larger networks. This reduction in overhead is critical for scaling ND6 to meet the demands of modern enterprise environments.
In this presentation, NITK students Sudesh, Advaith, and Kavya will elaborate on our hypothesis, the advanced packet modifications, and their efforts in implementing these upgrades in FreeRtr – an open-source IPv6 routing software. They have been actively involved in the implementation of these enhancement.

The 6LoWPAN adaptation layer defines compression, fragmentation and reassembly, and frame delivery mechanisms for IPv6 datagrams. As specified in RFC 4944, when an entire IPv6 datagram fits within a single IEEE Std 802.15.4 frame, then the datagram is transmitted unfragmented without adding a fragmentation header in the LoWPAN encapsulation. On the opposite hand, if the compressed IPv6 datagram is larger than the IEEE Std 802.15.4 MTU (i.e., 127 bytes), then fragmentation is required to split the large datagram into multiple link-layer fragments of up to 127 bytes. The length of each link fragment is specified in multiples of eight bytes. The first part of this talk will be dedicated to the whole process of 6LoWPAN Fragmentation and Reassembly operation. The second part of the talk will be dedicated to 6LoWPAN Frame Delivery modes, the mesh under and the route over (or Per-Hop Fragmentation and Reassembly mode). Both approaches are widely employed in the Smart Grid networks around the world. The first mode takes place at the 6LoWPAN adaptation layer, where the nodes require the knowledge of the routes at Layer 2 based on MAC, whereas the second mode does it at Layer 3 based on IP. Finally, in the third and last part of the talk, an alternate approach called 6LoWPAN Fragment Forwarding (6LFF), i.e., RFC 8930, will be presented, whereby an intermediate node forwards a fragment without reassembling the complete IPv6 datagram first.

Mesh routing is difficult, mesh routing for low power and lossy networks is straight up comatose. This session will help understand how the signalling/messaging works and depict sample packet captures for RPL signalling from real environments. It will also introduce tools apart from wireshark, such as scapy that can help construct/deconstruct the messaging. Obtaining performance data for mesh networks is another aspect covered in the session. What makes taking performance difficult? What are the best practices and some of the case studies? The session will also provide a demo into creating a sample 10 node RPL network on a laptop and getting the packet capture for the network formation.

RPL, the IETF standard for routing in low power lossy networks, was designed to meet unusual constraints in terms of scale (high), device capabilities (limited), and link reliability and capacity (very low). To meet those constraints, RFC 6550 introduced a number of innovations with the use of anisotropic routing, stretched P2P path, autonomic properties, objective functions, multi-topology routing, and a distance-vector operation that is proactive in setup but reactive in maintenance. RPL is now being extended at one extreme with a fully ADHOC mode called AODV RPL, and a centrally controlled mode called Route Projection. This session will browse through the main features of RFC 6550 and the route projection work.

In this IPv6 and 6LoWPAN Webinar, a detailed overview of the 6LoWPAN Adaptation layer will be given. Indeed, this webinar is dedicated on how 6LoWPAN enables to use of IPv6 over IEEE Std 802.15.4 networks. During this webinar, the following three objectives will be covered:
- First, the principles of IPv6 Header Format overview will be given, then the constraints that IPv6 presents over IEEE Std 802.15.4 technology are explored, and finally, an overview on 6LoWPAN Adaptation layer is introduced.
- The second objective is dedicated on 6LoWPAN header compression (i.e., RFC 6282) and IPv6 packet fragmentation mechanisms (i.e., RFC 4944) that allow the transmission of IPv6 packets over IEEE Std 802.15.4 radio links.
- The third and the last objective of this webinar is dedicated on standardized fragment forwarding approaches. This objective is split in two parts. In the first part, the two Frame Delivery modes (i.e., Mesh-Under and Route-Over) are described, while in the second part, an alternate approach called 6LoWPAN Fragment Forwarding (6LFF) is introduced, whereby an intermediate node forwards a fragment without reassembling the complete IPv6 datagram first (i.e., RFC 8930). Moreover, a 6LoWPAN Selective Fragment Recovery mechanism will be presented (i.e.,RFC 8931).

Despite the general benefits experienced with converging data, mail, voice, and video over IP, a number of domains in Operational Technology (OT) including Industrial IoT, vehicular automation, professional audio, and so on, still rely on semi-proprietary technologies for their the network operations. This is because machine-to-machine communications require deterministic properties such as guaranteed worst case latency and jitter and high reliability that traditional IP, which is based on statistical multiplexing and reactive congestion management, cannot offer.
In recent years, new work at IEEE 802.1 TSN and at the IETF with 6TiSCH, DetNet, and RAW, propose an evolution to IP networks that enable those deterministic properties for well characterized flows, over initially wired and then wireless networks. This session will introduce the concept of deterministic networking and how it applies to IoT, keeping in mind that machines are not necessarily small and constrained, and that automation applies to large things such as trains and nuclear plants. The architectures behind DetNet, 6TiSCH, and RAW, how they relate and specifically how they can leverage IPv6, will be browsed at a high level.

Microcontrollers have enabled adding processing and communication to many physical objects, but the result is not a simple copy of a general-purpose computing environment. Bringing these objects into the Internet requires attention to their specific constraints. Since 2005, the Internet Engineering Task Force (IETF) has been shaping Internet protocols towards the special requirements of such constrained devices, addressing a full stack from adaptation layers to the application layer, including security protocols. Looking at 17 years of standardization, what have we achieved, and what still needs to be completed to arrive at a true Internet of Things?

This is part of our “Migration Considerations for IPv6” series of educational webinars.
IP address Management (IPAM) is a critical tool of modern enterprise networks. IPAM not being a set Standard means there is a lot to consider when choosing an IPAM strategy and tool. IPv6 can present challenges due to its sheer scale of available IP Addresses. We will walk through features that can make this a seamless process and how tools can dramatically improve our IPAM solution’s accuracy and depth of information. We will finish up with a dive into the role our IPAM solution plays in overall enterprise security.
This is part of our “Migration Considerations for IPv6” series of educational webinars.
DHCP is so much more than assigning an IP address in our modern network environments. When moving to IPv6, this means we have a lot to consider and address.
This is part of our “Migration Considerations for IPv6” series of educational webinars.
DNS is often an overlooked aspect of any network environment. When moving to IPv6, this is an important aspect that must be planned for and addressed.
In this presentation Uma Chunduri talks about evolving 5G deployments in operator networks, in Multi-access Edge Clouds (MECs) as well as on-prem edges from requirements to network challenges. He talks about the ubiquitous and intelligent computing demands and usage of IPv6 in these deployments. He also talks about some of the unaddressed challenges in the network layer.

Concerned about adding a new protocol to your IP stack? Is someone in your company demanding that you have that capability on your mainframe? Don’t know what needs to be done and how much effort is involved? And what does it all mean?
Rob has done the hard work for you and can tell you what it takes to enable your mainframe systems for IPv6. This presentation will give you the few steps you need to get you going, to get IPv6 active on your z/OS system.
Rob started programming mainframe computers in 1971, and learned an exceptional array of languages, tools and techniques, all without internet assistance. He did some dazzling database work in the `80s, and wrote over half of the first online registration system for the University of Toledo. In the ‘90s he did contracts with three oil companies, a software company and a credit bureau, involving VM, MVS, VSE, OS/2, several flavors of Unix, and an equal variety of networking protocols. He is now with Chemical Abstracts Service, a division of the American Chemical Society, supporting z/OS, z/VM and Linux, along with proprietary networking software. He has been involved with and a fan of IPv6 since early this century, performing the configuration and software upgrades required to support it on the mainframe. He happily notes that the mainframe was the first platform configured for it, with applications using IPv6 sockets exclusively. Rob is also co-author of RFC8250.

Presented by Nalini Elkins & Michael Ackermann.
This session discusses the ways enterprises might want to think about migration to IPv6. Some vulnerabilities may be the same as IPv4 while other will be different. Vulnerabilities may be introduced by additional complexity, for example, transition mechanisms or dual-stacking.When many enterprises think about security, a number of areas are involved. These include:
- Audits/Compliance
- Threat detection
- Risk analysis
- Root cause determination
- Encryption
- Privacy
- Confidentiality
- Penetration testing
Presented by Nalini Elkins.

Enterprises rarely switch over from IPv4 to IPv6 in one step. Generally, companies will run dual-stack for a time, where both IPv4 and IPv6 are available on devices. This doesn’t solve most of the problems IPv6 was designed to solve, so we will discuss the benefits and drawbacks of:
- Dual-stack
- NAT44
- Dual-stack Lite
- NAT64/DNS64
- 464xlat
- MAP-T
- MAP-E
- IPv6-Only
