To provide secure and efficient access control methods in cloud computing environments, many system models have been proposed that employ attribute-based encryption and proxy re-encryption schemes. Most of these access control schemes are based on the user’s authentication information and access privileges. However, when users request access privileges through non-secure environments such as mobile devices and wireless networks, we need to be able to restrict access requests, depending on the user’s context-aware information. To achieve this, in this paper we propose an access restriction scheme for access to cloud data that is based on context-aware information.
