Microblogging is a popular activity within the spectrum of Online Social Networking (OSN), which allows users to quicky exchange short messages. Such systems can be based on mobile clients that exchange their group-encrypted messages utilizing local communications such as Bluetooth. Since however in such cases, users do not want to disclose their group memberships, and thus have to wait for other group members to appear in the proximity, the message spread can be slow to non-existent. In this paper, we solve this problem and facilitate a higher message spread by employing a server that stores the messages of multiple groups in an Oblivious RAM (ORAM) data structure. The server can be accessed by the clients on demand to read or write their group-encrypted messages. Thus our solution can be used to add access pattern privacy on top of existing microblogging peer-2-peer architectures, and using an ORAM is a promising candidate to use in the given application scenario. |
