“…Recently, 3D integrated circuits have emerged as a practical industrial option that reduces some design constraints, such as long interconnect, yield, and levels of integration. 3D has been proposed several times for security application [32] [33], but only very recently has it been advocated as a platform for the detection of intrusive side-channel attacks [34]. Also, the use of configurable shields against side-channel attacks has been explored [35].…”

Small form, mobile, and remote sensor network systems require secure and ultralow power data collection and communication solutions due to their energy constraints. The physical unclonable function (PUF) has emerged as a popular modern low power security primitive. However, current designs are analog in nature and susceptible to instability and difficult to integrate into existing circuitry. In this paper, we present the digital PUF which is stable in the same sense that digital logic is stable, has a very small footprint and very small timing overhead, and can be easily integrated into existing designs. We demonstrate the use of the digital PUF on two applications that are crucial for sensor networks: trusted remote sensing and logic obfuscation. We present our security analysis using standard randomness tests and confusion and diffusion analysis, and apply our new obfuscation approach on a set of standard design benchmarks.

“…We consider the trust issues of split manufacturing in [8] and establish that our threat model includes unintentional hardware design flaws and malicious software in the computation plane; the threats of hardware Trojans (i.e., malicious inclusions), physical tampering/probing, simple/differential power analysis, and compromising RF/acoustic/photonic emanations are outside the scope of our work. A first-order concern is whether the output of the unsecured foundry needs to be independently trustworthy for the joined system to provide certain trustworthy functions.…”

“…If so, it would seem to obviate the purpose of the effort. For option 3, we found that the independence of a control plane from interference by the computation plane (through active corruption of the processing or passively, via withholding of services) is a primary requirement for trustworthy behavior of the control plane [8]. However, the control plane can often choose whether to establish dependencies on the computation plane.…”

“…We believe it is not yet possible to add a layer of hardware to a computation plane that is riddled with malicious inclusions -effectively bearing an unknown degree of resemblance to its design -in the hopes that the composition of the two layers will be highly trustworthy. Nevertheless, provided that the requirements of self-protection and dependency layering are met for the control plane, it is possible to offer an alternate service to the computation plane, to actively override the computation plane for enforcement of policies, and to passively monitor the computation plane with high integrity [8]. Note that while option 3 allows a control plane to access the internal signals of a computation plane, this is not possible via the circuit board level coprocessor interface associated with option 2.…”

In this Technical Report, we describe a 3D architecture that splits a design into two separate tiers: one tier that contains critical security functions is manufactured in a trusted foundry; another tier is manufactured in an unsecured foundry.
