Abstract
A storage system stores information about a graph in an encrypted form. A query module can submit a token to the storage system to retrieve specified information about the graph, e.g., to determine the neighbors of an entity in the graph, or to determine whether a first entity is connected to a second entity, etc. The storage system formulates its reply to the token in a lookup result. Through this process, the storage system gives selective access to information about the graph to authorized agents, yet otherwise maintains the general secrecy of the graph from the perspective of unauthorized agents, including the storage system itself. A graph processing module can produce encrypted graph information by encrypting any representation of the graph, such as an adjacency matrix, an index, etc.
