Efficient Asymmetric Index Encapsulation Scheme for Named Data
2016
We are studing the problem of searching on hidden index in asymmetric setting. We define a mechanism that enables receiver to provide a token to the server and enables the server to test whether an encapsulated index matches the token without learning anything else about them. We refer to this mechanism as Asymmetric Index Encapsulation. We suggest to using the AIE as the core protocol of anonymous content-oriented networking. A construction of AIE which strikes a balance between efficiency and security is also given. Our scheme is proved secure base on the DBDH/CDH assumption in the random oracle with tight reduction, while the encapsulated header and the token in our system consists of only three elements.
