A (k, n)-traceability scheme is a scheme in which at least one traitor is detected from a pirate key if there are at most k traitors among n authorized users. It has four components: key generation, an encryption algorithm, a decryption algorithm and a tracing algorithm. Kurosawa and Desmedt found lower bounds on the size of keys and the size of ciphertexts of traceability schemes [1]. They als...

Agile methodologies represent a set of development processes in which both the requirements and the delivered solution evolve incrementally through a series of short iterations. Such projects are characterized by an emphasis on human interactions and collaborations, lightweight development processes, frequent deliverables, and minimal documentation (Ambler, 2004; Beck and Andres, 2004; Cockburn...

Requirements traceability allows us to assure the continuous concordance between the stakeholders requirements and the artifacts produced along the software development process. Although the important role of requirements traceability is widely recognized, the application level and consensus about associated practices are quite variable from one software development team to another. UML appears...

Global food industry and Governments in many countries are putting increasing emphasis on establishment of food traceability systems. Food traceability has become an effective way in food safety management. Aimed at the major quality problems of cereal and oil products existing in the production, processing, warehousing, distribution and other links in the supply chain, this paper firstly propo...

This report documents the program and the outcomes of Dagstuhl Seminar 15162 on “Software and Systems Traceability for Safety-Critical Projects”. The event brought together researchers and industrial practitioners working in the field of safety critical software to explore the needs, challenges, and solutions for Software and Systems Traceability in this domain. The goal was to explore the gap ...

Requirements are at the core of all project deliverables. Ensuring that all project requirements are achieved by the project can be difficult to validate if no further means of tracing requirements is employed. Requirements traceability hence is a critical component of any project, as it provides the ability for a project to articulate how any given requirement has been met by the project deliv...

Food safety problems such as the BSE and dioxin crises focused attention on traceability systems and the certification of such systems. This study analyzes the status and perspectives of traceability systems and certification schemes, and reviews their potential costs and benefits. Results indicate that traceability and certification in meat supply chains comprise a very dynamic area with an in...

Please cite this article in press as: Bergquist, B. The ability to track and trace products in a production process and in the transportation chain from supplier to customers is important for quality control and process improvements. However, good traceability is often difficult achieve for continuous process products as well as for batch produced products where batches intermix. In this paper,...

This thesis addresses the problem of model-to-model traceability in Model Driven Engineering (MDE). A MDE process typically involves models expressed in different modelling languages that capture different views of the system under development. To enhance automation, consistency and coherency, establishing and maintaining semantically rich traceability links between models used throughout the s...
