Summary:
Cloud computing is a unified management and scheduling model of computing resources. To satisfy multiple resource requirements for various application, edge computing has been proposed. One challenge of edge computing is cross-domain data security sharing problem. Ciphertext policy attribute-based encryption (CP-ABE) is an effective approach to ensure data security sharing. However, many existing schemes focus on could computing, and do not consider the attributes of edge computing. In order to address this issue, we propose a cross-domain data security sharing approach for edge computing based on CP-ABE. Besides data user attributes, we also consider edge node attributes. Our scheme calculates public-secret key of each edge node based on its attributes, and uses it to encrypt secret key of data ciphertext to ensure data security. In addition, our scheme can add non-user access control attributes such as time, location, frequency according to the different demands. Finally, simulation experiments and analysis exhibit the feasibility and effectiveness of our approach.
