Current and future software needs to remain focused towards the development and deployment of large and complex intelligent and networked information systems, required for internet-based and intranet-based systems in organizations. Today software covers a very wide range of application domains as well as technology and research issues. This has found realization through Cloud Computing. Vital element in such networked information systems are the notions of trust, security, privacy and risk management. Cloud and Trusted Computing (C&TC 2015) is the 5th International Symposium on Cloud Computing, Trusted Computing and Secure Virtual Infrastructures, organized as a component conference of the OnTheMove Federated Conferences & Workshops. C&TC 2015 will be held in Rhodes, Greece. The conference solicits submissions from both academia and industry presenting novel research in the context of Cloud Computing, presenting theoretical and practical approaches to cloud trust, security, privacy and risk management. The conference will provide a special focus on the intersection between cloud and trust bringing together experts from the two communities to discuss on the vital issues of trust, security, privacy and risk management in Cloud Computing. Potential contributions could cover new approaches, methodologies, protocols, tools, or verification and validation techniques. We also welcome review papers that analyze critically the current status of trust, security, privacy and risk management in the cloud. Papers from practitioners who encounter trust, security, privacy and risk management problems and seek understanding are also welcome.
