Abstract
Despite the rapid expansion and uptake of cloud based services, lack of trust in the provenance of such services represents a significant inhibiting factor in the further expansion of such service. This paper explores an approach to assure trust and provenance in cloud based services via the generation of digital signatures using properties or features derived from their own construction and software behaviour. The resulting system removes the need for a server to store a private key in a typical Public/Private-Key Infrastructure for data sources. Rather, keys are generated at run-time by features obtained as service execution proceeds. In this paper we investigate several potential software features for suitability during the employment of a cloud service identification system. The generation of stable and unique digital identity from features in Cloud computing is challenging because of the unstable operation environments that implies the features employed are likely to vary under normal operating conditions. To address this, we introduce a multi-dimensional key generation technology which maps from multi-dimensional feature space directly to a key space. Subsequently, a smooth entropy algorithm is developed to evaluate the entropy of key space.

Summary
Along with the popularity of Cloud computing, the majority of mediumto small sizedcompanies start to deploy their servers on the third party Cloud computing service providers in order to reduce the costs. Due to the low boundary of technologies of setting up on Cloud servers, many malware or phishing sites can manipulate server using such vulnerabilities. For this reason, to the research topic of quickly identifying such web servers and protecting the customers’ private data is becoming an important research area. This paper introduces a technique termed ICMetrics that could be used to protect services located in a Cloud server, a digital signature could be generated using properties or features derived from the server’s own construction and behaviour [9].
