Interest forwarding for interactive client anonymity

摘要

In one embodiment, an intermediate node in a communication network receives a client interest with an indication of a client-requested reverse private path. The reverse private path is a label switched path toward a corresponding client with encrypted client information. In response to receiving the client interest, the intermediate node allocates a label for the reverse private path. The allocated label is mapped to a node from which the client interest is received. The intermediate node then forwards the client interest with the allocated label toward a server. In another embodiment, the server receives a client interest including a client-requested reverse private path from a particular intermediate node and determines a server interest. The allocated label for the client interest is inserted into the server interest which is forwarded toward the client via the particular intermediate node using the allocated label for the reverse private path.

主权项

1. A method, comprising:
receiving, at an intermediate node in a communication network, a client interest with an indication of a client-requested reverse private path, wherein the client-requested reverse private path is a label switched path toward a corresponding client with encrypted client identifying information; in response to receiving the client interest, allocating a label for the client-requested reverse private path, wherein the label is mapped to a node from which the client interest is received; forwarding the client interest with the allocated label toward a server, wherein the corresponding client remains anonymous while the client interest is transmitted between a source and a destination, and the label automatically expires after a predetermined amount of time of non-use at the intermediate node; receiving, at the intermediate node, a server interest by encapsulating the server interest in the allocated label, wherein a client name is encrypted in the server interest; and forwarding the server interest toward the client via the mapped node based on the allocated label of the server interest.
