It is important to preserve the integrity of a product as it is transported through the channel of distribution and delivered to the final consumer. In real world cases, manufacturing plants are sited at different parts of the world. Thus, it is an absolute necessity to have a secure mechanism which allows the supply chain integrity to be preserved. In this paper, we proposed a novel three-way bounded protocol for generating asserted holding and transferal proofs for preserving the integrity of the supply chain system. Additionally, the proofs are used to create a provenance chain for preserving the chronological order of the path of the product. The proposed protocol allows us to ensure the authenticity of the product with respect to its supply chain. We also provide a security analysis of the proposed architecture to illustrate the feasibility of the design.

“…Unfortunately, as signal strength is inherently and easily spoofable, all such systems fail against even basic adversaries. While a number of techniques have been designed to combat against location forgery [2], [19], [23], these mechanisms rely on signal strength, which can be spoofed by an adversary.…”

Abstract-Proof of a user's identity is not always a sufficient means for making an authorization decision. In an increasing set of circumstances, knowledge of physical location provides additional and necessary context for making decisions about resource access. For example, sensitive information stored on a laptop (e.g. customer records, social security numbers, etc), may require additional protections if a user operates outside of an approved area. However, current localization techniques based on signal strength reporting or specialized hardware fail to achieve this goal. In this paper, we design, develop, deploy and measure a system which securely determines the location of a user to within one meter through using only off-the-shelf 802.11 and Bluetooth equipment. We apply this equipment in a two-phased challengeresponse protocol: first determining the general area of the client in the Regionalization phase and then pinpointing it in the Localization phase. Using nearly 32,000 data points collected over 75 days, we argue that the stability of wireless networks over time creates easily distinguishable location profiles by which a client can be positioned. Additionally, we demonstrate the inherent ability of a two-phased protocol to discern a client's location information at a level of granularity no finer than is necessitated by policy. After discussing a number of applications, we build a location-based access control framework that automatically protects a white-listed set of resources through encryption when the user leaves specified areas. Our analyses show that this system provides a realistic and efficient means of incorporating unforgeable location information at the appropriate level of granularity into many authorization decisions.

In this work, we study the security of public WLAN-based positioning systems. Specifically, we investigate the Skyhook positioning system, available on PCs and used on a number of mobile platforms, including Apple's iPod touch and iPhone. By implementing and analyzing several kinds of attacks, we demonstrate that this system is vulnerable to location spoofing and location database manipulation. In both, the attacker can arbitrarily change the result of the localization at the victim device, by either impersonating remote infrastructure or by tampering with the service database. Our attacks can easily be replicated and we conjecture that-without appropriate countermeasures-public WLAN-based positioning should therefore be used with caution in safety-critical contexts. We further discuss several approaches for securing WLAN-based positioning systems.
