EditMF: Drawing an Invisible Fingerprint for Your Large Language Models
Training large language models (LLMs) is resource-intensive and expensive, making protecting intellectual property (IP) for LLMs crucial. Recently, embedding fingerprints into LLMs has emerged as a prevalent method for establishing model ownership. However, existing back-door-based methods suffer from limited stealth and efficiency. To simultaneously address these issues, we propose EditMF, a training-free fingerprinting paradigm that achieves highly imperceptible fingerprint embedding with min…

Happy to see the progress on this. Thought you might be interested in seeing how important this feature is going to be for the Small Web: It’s going to be invaluable for helping decentralise the web. Thank you for the work you do 🙂

Designing with Deception: ML- and Covert Gate-Enhanced Camouflaging to Thwart IC Reverse Engineering
Integrated circuits (ICs) are essential to modern electronic systems, yet they face significant risks from physical reverse engineering (RE) attacks that compromise intellectual property (IP) and overall system security. While IC camouflage techniques have emerged to mitigate these risks, existing approaches largely focus on localized gate modifications, neglecting comprehensive deception strategies. To address this gap, we present a machine learning (ML)-driven methodology that integrates cryp…

Psylo Browser Obscures Digital Fingerprints By Giving Every Tab Its Own IP Address - Slashdot

IPv4 prices seem to have come down recently. But it is still much better than when I sold a /16 I sold a few years back.
I still can't believe that the Interop company - a for-profit corporation - simply gave away a /8. I don't think the officers/directors knew the value of the asset they gave away.
I've been prediction that the net will fragment into distinct IP address spaces - many full 32-bit IPv4 and many full 128-bit IPv6 spaces connected by application level …

Today in #ITSecurity gone wrong: I am in Austria as a German. I just received a notification via cell broadcast about a fire in the area.

Improving performance of content-centric networks via decentralized coded caching for multi-level popularity and access
Content-Centric Networking (CCN) offers a novel architectural paradigm that seeks to address the inherent limitations of the prevailing Internet Protocol (IP)-based networking model. In contrast to the host-centric communication approach of IP networks, CCN prioritizes content by enabling direct addressing and routing based on content identifiers. The potential performance improvements of CCN can be further amplified through optimized management of coded data storage and transmission strategies…

Web Numbers
Domains? Where we’re going, we don’t need domains! Until the end of this year, the only way to have a secure web site is to have it accessible via a domain name. That, however, is changing. And the design of the Small Web will be changing along with it. IP addresses are about to make a comeback on the web in a big (ok, small) way, thanks to upcoming support for security certificates for IP addresses by Let’s Encrypt.

The correct regional coding for a "London" IP address in RFC 8805 is
10.0.0.0/16,GB,GB-ENG,London,
This is because there is no ISO 3166-2 code for London, just for its individual boroughs. The code GB-LND is often used to represent London, but this specifically identifies City of London which has the property of being London's central point geographically, but is not London itself.

Automatic integration of SystemC in the FMI standard for Software-defined Vehicle design
The recent advancements of the automotive sector demand robust co-simulation methodologies that enable early validation and seamless integration across hardware and software domains. However, the lack of standardized interfaces and the dominance of proprietary simulation platforms pose significant challenges to collaboration, scalability, and IP protection. To address these limitations, this paper presents an approach for automatically wrapping SystemC models by using the Functional Mock-up Int…

Variability in energetic particle observations at strong interplanetary shocks: Multi-spacecraft observations
Context. Interplanetary (IP) shock waves offer an unparalleled opportunity to directly study the elusive mechanisms of particle acceleration that are pervasive in our Universe. Novel spacecraft missions, orbiting poorly-explored regions of the heliosphere, opened a new observational window on particle acceleration at IP shocks that is relevant to space and astrophysical plasmas. Aims. We address shock variability and its effects on the production of accelerated particles at different energies. …

Unlocking the Effectiveness of LoRA-FP for Seamless Transfer Implantation of Fingerprints in Downstream Models
With the rapid advancement of large language models (LLMs), safeguarding intellectual property (IP) has become increasingly critical. To address the challenges of high costs and potential contamination in fingerprint integration, we propose LoRA-FP, a lightweight, plug-and-play framework that embeds backdoor fingerprints into LoRA adapters through constrained fine-tuning. This design enables seamless fingerprint transplantation via parameter fusion, eliminating the need for full-parameter updat…

Time Tells All: Deanonymization of Blockchain RPC Users with Zero Transaction Fee (Extended Version)
Remote Procedure Call (RPC) services have become a primary gateway for users to access public blockchains. While they offer significant convenience, RPC services also introduce critical privacy challenges that remain insufficiently examined. Existing deanonymization attacks either do not apply to blockchain RPC users or incur costs like transaction fees assuming an active network eavesdropper. In this paper, we propose a novel deanonymization attack that can link an IP address of a RPC user to …

Design of a Timer Queue Supporting Dynamic Update Operations
Large-scale timers are ubiquitous in network processing, including flow table entry expiration control in software defined network (SDN) switches, MAC address aging in Ethernet bridges, and retransmission timeout management in TCP/IP protocols. Conventional implementations suffer from critical limitations: low timing accuracy due to large-scale timer traversal and high computational overhead for new timer insertion. This paper presents a hybrid-architecture hardware priority queue based on syst…

Intellectual Property in Graph-Based Machine Learning as a Service: Attacks and Defenses
Graph-structured data, which captures non-Euclidean relationships and interactions between entities, is growing in scale and complexity. As a result, training state-of-the-art graph machine learning (GML) models have become increasingly resource-intensive, turning these models and data into invaluable Intellectual Property (IP).
