碩士 === 國立臺灣海洋大學 === 資訊工程學系 === 102 === In cloud computing, large data and complex calculations were divided into smaller processes and assigned dynamically to different virtual servers in the cloud for computation. With the increased in data transmissions across platforms and servers, data encryption should be in place to secure the confidential data and to protect proprietary algorithms; while designated protocol will be used to ensure the accuracy of the calculation results. This thesis presents a computation delegation using circuits hiding key-policy attribute-based encryption. And when used in cloud computing, it could detect errors in calculation and prevents the servers from knowing the exact algorithms used in the computation delegation. The system is based on multilinear maps and is proven selectively secure under k-MDDH assumption.
