Modular Formal Spe i ation of Data and Behaviour

Abstra t. We propose a modular approa h to the formal spe i ation of the requirements on embedded systems. In this approa h, requirements on data are spe i ed as invariants on states. Requirements on behaviour are spe i ed assertionally by temporal logi formulae, restri ting the runs of the system. The proposed method is modular, be ause omponents an be spe i ed and analysed in isolation, and t...

Modal Specifications of Trace-Based Security Properties

We introdu e a multi-modal logi that ombines omplementary features of authenti ation logi s and tra e-based approa hes. Our logi ontains two kinds of modalities: impli it belief, whi h formalizes the view of an external agent reasoning about interleaved proto ol exe utions, and expli it belief, whi h uses awareness to model the resour e-bounded reasoning of the agents involved in the exe utions...

Verifiable Multi-agent Programs

AgentSpeak is a rea tive planning language for programming autonomous agents. It has re ently been shown that model he king te hniques an be applied to the veri ation of AgentSpeak systems, through a translation to promela, the model spe i ation language for the SPIN LTL modelhe king system. In this paper, we introdu e an alternative veri ation approa h for AgentSpeak, by translating AgentSpeak...

Abstra t. In this paper we dis uss how the spe i ation of omponents may be separated from the des ription of the ontext in whi h they are used. There are a number of ways in whi h this might be possible and here we show how to use the te hnique of promotion in Obje t-Z to ombine omponents whi h are spe i ed using pro ess algebras. We dis uss two approa hes, the rst is to separate out the spe i ...
