In this paper, we analyze the security of an RFID authentication protocol proposed by Liu and Bailey [1], called Privacy and Authentication Protocol (PAP), and show its vulnerabilities and faulty assumptions. PAP is a privacy and authentication protocol designed for passive tags. The authors claim that the protocol, being resistant to commonly assumed attacks, requires little computation and pr...

Combined with identity-based signature technology and non-interactive proof, a dynamic group signature scheme was built based on the standard group scheme model. This scheme overcame the shortcoming of static property of standard scheme and was of strong Non-frameability. New members could dynamically join in group without updating the group public key and group manager could not forge any memb...

With the development of science and technology, the problem about the quality safety traceability of agricultural products has already become the hot topic of researchers in various fields. Cucumber is one of the main vegetable crops in China. It is convenient for eating and contains various beneficial minerals. With the constant expansion of the planting areas, it plays a more and more importa...

With the competitive differentiators of supply chain operation’s efficiency, food differentiation with credence attributes, quality enhancement and food safety, the concept of “traceability as strategy and mandatory initiative” has replaced that of “traceability as a cost of a business or as a voluntary responsibility”. This implies that the introduction of a traceability system should be perce...

Software traceability is becoming increasingly significant element in software development life cycle. From the software evolution point of view, software traceability is one of importance factor in facilitating software evolution. Unfortunately, practicing software traceability is much harder than it would appear. On the other hand, software evolution is inevitable since software must be conti...

Model management operations such as refinement and transformation modify existing or produce new models. To assist both engineers and tools in tracing the path of changes and decisions, maintenance of traceability information is essential. There are two main approaches for storing traceability; in the first, traceability information is embedded inside the models, while in the second, traces for...

Requirements traceability is an essential step in ensuring the quality of software during the early stages of its development life cycle. Requirements tracing usually consists of document parsing, candidate link generation and evaluation and traceability analysis. This paper demonstrates the applicability of Statistical Term Extraction metrics to generate candidate links. It is applied and vali...

Software traceability, is recognized for its utility in many development activities. Achieving traceability in practice, however, is difficult because of the complex interaction between factors like high costs, heterogeneous artifacts and tools, and varied stakeholder interests. Architecture-Centric Traceability for Stakeholders (ACTS) is a technical framework that considers the economic and so...

Abstract : an approach for managing complexity through requirements elicitation and traceability model. The approach makes use of two approaches development. The first on a traceability model that have been developed and applied to a complex industrial system and a requirement elicitation approach and tool. The paper makes use of these approaches and show how a traceability even at requirement ...
