The Eighth International Workshop on Security in Blockchain and Cloud Computing SBC 2020, Taipei, Taiwan, June 1-5, 2020, (Submissions due 31 January, 2020) Cloud computing has emerged as today's most exciting computing paradigm shift in information technology. With the efficient sharing of abundant computing resources in the cloud, users can economically enjoy the on-demand high quality cloud applications and services without committing large capital outlays locally. While the cloud benefits are compelling, its unique attributes also raise many security and privacy challenges in areas such as data security, recovery, privacy, access control, trusted computing, as well as legal issues in areas such as regulatory compliance, auditing, and many others. To implement secure and privacy-aware environments which can provide on-demand computing and high-quality service for cloud users is extremely urgent. Blockchain is another paradigm shift and drew a lot of recent attention from both academia and industry. Moreover, blockchain and cloud have many interplays. Building on the success of 7 versions of the International Workshop on Security in Cloud Computing (SCC), held often with ACM AsiaCCS, we plan this year to rebrand it to include blockchain as well and organize this workshop again for the eighth edition. This workshop is intended to bring together researchers, developers, and practitioners in security, privacy and mobile computing communities. We will encourage submissions on all theoretical and practical aspects, as well as experimental studies of deployed systems. Topics of interest include (but are not limited to) the following subject categories: - Secure cloud architecture - Cloud cryptography - Cloud access control and key management - Identification and privacy in cloud - Integrity assurance for data outsourcing - Integrity and verifiable computation - Computation over encrypted data - Software and data segregation security - Secure management of virtualized resources - Trusted computing technology - Failure detection and prediction - Secure data management within and across data centers - Availability, recovery and auditing - Secure mobile cloud - Privacy and anonymity cloud applications - Secure cloud for critical services (e.g., healthcare or finance) - Blockchain security - Blockchain consensus protocols - Blockchain in edge and cloud computing - Privacy and anonymity in blockchain applications - Decentralized internet infrastructure - Decentralized applications - Interplay between blockchain and cloud For more information, please see https://conference.cs.cityu.edu.hk/asiaccsscc/
