EAI SPNCE 2020 - 3rd EAI International Conference on Security and Privacy in New Computing Environments, Lyngby, Denmark, July 27-28,2020 (Submissions due 17 February 2020). All registered papers will be submitted for publishing by Springer and made available through SpringerLink Digital Library, and authors of selected papers will be invited to submit an extended version to: Mobile Networks and Applications (MONET) Journal, Wireless Communications and Mobile Computing (WCMC) Journal. The existing computing models and computing environments have changed immensely due to the rapid advancements in mobile computing, big data, and cyberspace-based supporting technologies such as cloud computing, Internet-of-Things (IoT), blockchain, and other large-scale computing environments. In recent years, we have witnessed an ever-growing research interest in this field, and the key reason is its essential properties that provide security, anonymity, and data integrity without any third-party organization in control of the transactions. On the other hand, its advance should be further supported with better scalability, privacy, efficiency, flexibility, availability, and higher dependability. Traditional security techniques are faced with many challenges in these new computing environments. Thus, efforts are needed to explore the security and privacy issues of the above-mentioned new environments within the cyberspace. Particular topics of interest include, but are not limited to: New Cryptographic Techniques for New Computing Environments Remote Data Deduplication Science of Cyber security Secure and Outsourcing Computation Secure Cloud Model and Architecture Secure Cloud Storage Security and Privacy in Big Data Security and Privacy in Blockchain Security and Privacy in IoT Software and data segregation security Theory and Application of Cryptology For more information, please see http://spnce.org/
