KEY MANAGEMENT FOR ENCRYPTED STORAGE ON A GRID

摘要

Data grids provide data owners with a tremendous volume of data storage capacity. Sensitive data stored oil a grid is vulnerable to unauthorized disclosure because grids are an open environment. Encrypting data provides data with confidentiality in store and in transit. However. if doing so, the main problems are how to store those cryptographic keys safely and how to allow the authorized users to have access to the cryptographic keys. In this paper. a scheme is proposed for data owners to store encrypted data and to share the data with authorized users in an efficient way.
