Traditional temporal logic regards protocols as close system to analyze. In order to overcome the shortcoming of traditional temporal logic, an game-based analysis method is inducted. This method is applied to formal analyze a fair contract signing protocol, and then some defects of the protocol are found. An improvement protocol is proposed which fixes the flaw by adding some extra time limit information...
With the existing Cognitive Radio Networks development, we present a sub-spectrum sensing scheme based on reputation, which takes advantage in energy consumption, security and fairness from spectrum sensing, data fusion and spectrum allocation by classifying users and spectrum bands reasonably. The analysis shows that the sub-spectrum sensing scheme can save energy and defense SSDF attacks effectively.
Formal methods are effective in improving the safety and reliability during the development of software. PVS (Prototype Verification System) provides an integrated environment for development and analysis of formal specifications. It consists of a higher order logical specification language integrated with support tools and a powerful theorem prover. In this paper, we specify and verify the design...
