Quantitative Analysis for Authentication of Low-cost RFID Tags
Formal analysis techniques are widely used today in order to verify and
analyze communication protocols. In this work, we launch a quantitative
verification analysis for the low- cost Radio Frequency Identification (RFID)
protocol proposed by Song and Mitchell. The analysis exploits a Discrete-Time
Markov Chain (DTMC) using the well-known PRISM model checker. We have managed
to represent up to 100 RFID tags communicating with a reader and quantify each
RFID session according to the protocol's computation and transmission cost
requirements. As a consequence, not only does the proposed analysis provide
quantitative verification results, but also it constitutes a methodology for
RFID designers who want to validate their products under specific cost
requirements.Comment: To appear in the 36th IEEE Conference on Local Computer Networks (LCN

A HOLISTIC APPROACH FOR SECURITY REQUIREMENT SPECIFICATION FOR LOW-COST, DISTRIBUTED UBIQUITOUS SYSTEMS
The class of low-cost, distributed ubiquitous systems represents a computing mode where a system has small, inexpensive networked processing devices, distributed at all scales throughout business activities and everyday life. The unique features of such a class of ubiquitous systems make the security analysis different from that for the centralized computing paradigms. This paper presents a holistic approach for security requirement analysis for low cost, distributed ubiquitous systems. Rigorous security analysis needs both quantitative and qualitative approaches to produce the holistic view and the robust data regarding the security features that a system must have in order to meet users’ security expectations. Our framework can assist system administrators to specify key security properties for a low-cost, distributed ubiquitous system and to define the specific security requirements for such a system. We applied Bayesian network and stochastic process algebra to incorporate probabilistic analysis to the framework
