报告摘要：

I will start with a brief introduction on certain general aspects of trust. Then I will give a brief overview of the role based encryption scheme for secure cloud data storage that I talked about last year. Then I will talk about trust in role based encryption schemes for secure cloud data storage. Here I will describe two trust models, which we refer to as Owner-Role RBAC and Role-User RBAC trust models.

(i) Owner-Role RBAC Trust Model: assists the data owners to evaluate the trust on the roles in a RBAC system and helps to use this trust evaluation to decide whether to store their encrypted data in the cloud for a particular role, and

(ii) Role-User RBAC Trust Model: assists the roles or role managers to evaluate the trust on the users in the RBAC system and helps to use this trust in the decision whether to grant the membership to a user.
