Enforcing Dynamic Read and Write Privileges

Abstract

As illustrated in Chap.  1 of this book, users and companies are more and more resorting on external providers for storing their data and making them available to others. When the release is selective, meaning that different users are authorized by the data owner to access different portions of the released data, there is the problem of ensuring that accesses to resources be allowed to authorized users only. Recent approaches based on selective encryption provide convenient enforcement of read privileges over outsourced resources, but are not directly applicable for supporting write privileges. In addition, they cannot easily support the enforcement of a subscription-based authorization policy where, due to new subscriptions and the publication of new resources, both the set of users who can access a resource and the set of resources change frequently over time. In this chapter, we build upon the selective encryption approach to propose an efficient solution for enforcing dynamic read and write privileges over outsourced data. We also define an effective mechanism for checking data integrity. Finally, we enhance our solution to effectively support the definition of subscription-based authorizations.
