We present a metaheuristic-based attack against the traceability of an ultra-lightweight authentication protocol for RFID environments called SLMAP, and analyze its implications. The main interest of our approach is that it constitutes a complete black-box technique that does not make any assumptions on the components of the underlying protocol and can thus be easily generalized to analyze many other proposals.

China has carried out of a lot of useful exploration in the quality and safety of agricultural products traceability, and developed a number of management platforms, but there are still many problems, for example supply and demand sides of information asymmetry, transaction costs and risks are too high, poor circulation products and other regulatory agencies and other parties can't effectively participate. This article from the perspective of the theory of the multisided platforms (MSPs), in the analysis of the important features of the MSPs on the basis of the theory, combined with the quality and safety of agricultural products traceability features, discussed on quality safety of agricultural products traceable method of constructing a multisided platform, particularly designed of the path multi-stakeholder participation, and analyzed its characteristics. It is of great significance for agricultural traceability information sharing to achieve symmetry, reduce transaction costs and risks, and the realization of smooth flow products.

This paper aims to address the challenges posed by the evolving landscape of measurements, especially in non-physical domains. With a growing need for informed decision-making, the landscape of measurements has expanded significantly. To address this, measurement procedures for non-physical measurements need to be developed. This paper proposes a framework for achieving traceability in non-physical measurements. A six-step process for the creation of novel measurements is suggested by the following steps. Define the underlying concept, dissect the concept into its constituent components, identify suitable measurement techniques, ensure the validity and reliability of chosen techniques, determine appropriate measurement scales and establish a reference for traceability.
