    Abstract: A computer system can send a secure request over a named-data network to a remote device by generating an Interest with encrypted name components. During operation, the computer system can receive or obtain a request for data, such as from a local user or from a local application. If the system cannot satisfy the request locally, the system can determine at least a routable prefix and a name suffix associated with the request. The system can generate the secure Interest for the request by determining an encryption key that corresponds to a session with the remote computer system, and encrypts the name suffix using the session encryption key. The system then generates an Interest whose name includes the routable prefix and the encrypted name suffix, and disseminates the Interest over a named-data network to send the request to the remote computer system.

    Abstract: One embodiment provides a system that facilitates secure communication between computing entities. During operation, the system generates, by a content-consuming device, a first key based on a first consumer-share key and a previously received producer-share key. The system constructs a first interest packet that includes the first consumer-share key and a nonce token which is used as a pre-image of a previously generated first nonce, wherein the first interest has a name that includes a first prefix, and wherein the first nonce is used to establish a session between the content-consuming device and a content-producing device. In response to the nonce token being verified by the content-producing device, the system receives a first content-object packet with a payload that includes a first resumption indicator encrypted based on a second key. The system generates the second key based on a second consumer-share key and the first content-object packet.

    Abstract: One embodiment of the present invention provides a system for retrieving a content collection over a network. During operation, the system determines additional information associated with the piece of content that is needed for consumption of the content collection; generates a plurality of Interests, which includes at least one Interest for a catalog of the content collection and at least one Interest for the additional information; and forwards, concurrently, the plurality of Interests, thereby facilitating parallel retrieval of the content collection and the additional information.
