Research Abstract

Cloud computing is useful because it enables us to easily share important data. However, as its tradeoff, we are faced with the risk of information leakage because we outsource our data to a third party. In this work, we utilize and improve the advanced cryptographic techniques such as attribute-based encryption and searchable encryption to realize secure and practical cloud computing environments.
