This project aims to enable dynamic access control due to organisational change, which is critical to enable the adoption of cloud computing in practice. Access control over encrypted outsourced data is an essential requirement for enabling practical, secure storage. This project will be underpinned by a study of constructing new cryptographic primitives for enabling cipher-text changes without the need for refreshing the users’ secret keys. The expected outcomes will bridge theory and practice, providing economic benefits to industry by enabling practical mechanisms to store confidential user’s information in the cloud, hence lowering the infrastructure cost for industry.

该项目旨在实现由于组织变化而导致的动态访问控制，这对于在实践中采用云计算至关重要。对加密外包数据的访问控制是实现实用、安全存储的基本要求。该项目将通过研究构建新的密码原语来支持密码文本的更改，而无需刷新用户的密钥。预期成果将在理论和实践之间架起桥梁，通过实现将机密用户信息存储在云中的实用机制，为行业提供经济效益，从而降低行业的基础设施成本。
