Abstract
Modern System on Chip (SoC) designs integrate numerous embedded instruments for testing, debugging, postsilicon validation, and in-field monitoring. The IEEE 1687 (IJTAG) standard provides scalable access through a reconfigurable scan network of Segment Insertion Bits (SIBs), but this flexibility exposes internal resources to unauthorized access through the test infrastructure. Existing protection approaches rely on fixed hardware mechanisms, limiting adaptability across device lifecycle phases. This work proposes a secure IJTAG architecture integrating an eFPGA between the TAP and the IJTAG network as a reconfigurable security layer that controls instrument cluster connectivity through authenticated configuration, enabling lifecycle-aware isolation while preserving IJTAG flexibility. The architecture is evaluated on IJTAG benchmark networks to assess scalability.
Experimental results show millisecond-level processing latency and a middleware overhead satisfies the real-time constraints of typical IIoT edge applications, while the reconfiguration latency satisfies the real-time constraints of typical IIoT edge applications.

An architectural analysis of automotive HSMs is presented and examines their role in establishing secure boot and hardware roots of trust and emerging challenges such as cryptographic agility and post-quantum readiness that are likely to shape the next generation of automotive HSM architectures are discussed.
Re-keying every 10 encryptions provides a practical and secure solution that limits the effectiveness of side-channel attacks, and the proposed lightweight architecture, named LISHARK, maintains the same area footprint as a standalone AES core, making it significantly more efficient compared to TI and DOM.

Buckle is presented, a framework that enables an MNO to deploy temporary, local, and reversible hotfixes in its radio access network (RAN) during this exposure window and establishes operator-empowered hotfixing as a practical and portable interim defense and delineate the architectural limits of RAN-only prevention.
