Traceability is an increasingly important aspect of the supply chain with several highlights throughout the last few decades. Parties, such as consumers and government agencies, have shown an increase in demand for information regarding their products and materials. Although there exist numerous frameworks for traceability solutions, these frameworks fail to address the concerns with regards to privacy-sensitive information, certificate verifiability, and auditability. Our contribution is in two-fold: a traceability system decouples and the product-auditable pasta protocol. decouples is the first decentralized, unlinkable and privacy-preserving traceability system for the supply chain, to the best of our knowledge. The system incorporates cryptographic techniques to address the aforementioned concerns. Our second contribution is the pasta protocol, which allows unique tracking keys per product, per actor. The protocol also anonymizes the receiver of a transaction. Our complexity analysis and proof-of-concept implementation results show that decouples is a feasible traceability system for the supply chain. ... Read more

Traceability has become an increasingly important aspect of the supply chain in the last few years due to customer awareness as well as better planning and problem identification. Unfortunately, technological, legal, and organizational concerns limit the possibility to utilize a centralized system to achieve traceability. Trust is one of the most important factors preventing the appliance of a centralized system. Previous works provided several approaches to create a decentralized traceability system. However, these works do not state the feasibility of their work and its appliance for the supply chain. In this paper, we propose a fully transparent and decentralized traceability system for the supply chain, namely TRADE. The system leverages the actors and supply chain structure to achieve traceability. Moreover, consumers and other parties can view all the data in the system and verify the claims of actors on the products. The latter results in positive brand reputation and auditability. ...

In order to protect ICT systems against remote attacks and exploitation, insight into which systems are targeted is necessary as soon as possible. Given the lack of advance information, current network-based attack detection and mitigation
techniques, such as virus scanners or intrusion prevention systems, are typically aimed at countering the delivery and exploitation. This paper presents a novel approach capable of detecting threats while they scan a local network for potential targets and even before an intrusion attack has been made. Thisallows the defender to single out scan traffic and selectively deny access to an attacker performing reconnaissance while maintaining the availability to other users.We implement a proofof-concept on commodity graphics cards, and demonstrate fast prediction of scanner behavior on a /16 network telescope. ...
