Abstract: One embodiment provides a system for facilitating efficient communication of a collection of interests. During operation, the system receives, by an intermediate node, a first packet which has a name and a first nonce, wherein the first packet indicates a set of member interests, wherein a member interest has a name. In response to not obtaining a matching entry in a pending interest table based on the name for the first packet, the system creates a new entry in the pending interest table, wherein an entry includes a second nonce, a reference count, and a set of arrival nonces and corresponding arrival interfaces. The system sets the new entry's second nonce to a new nonce, and sets the new entry's reference count to a number of member interests indicated in the first packet. The system forwards the first packet, wherein the first nonce is replaced with the new nonce.

The system transmits the first packet to another node.

Abstract: A networked interactive expert system is disclosed for selectively providing relevant expertise when a user requires such assistance. System provides a set of networked facilities for determining an expertise needed by a customer based on a location. Such location can be either physical or logical. A physical “location” corresponds, for example, to a department within a retail outlet. Examples of logical “locations” are ones corresponding to a web-page, a product identification code of interest, a customer identification code, and/or explicit knowledge category selected by the customer. An expert studio, from a list of expert studios providing expertise corresponding to the identified location associated with the customer's request, is matched up with the request. Thereafter, a primary connection, supporting an interactive videoconference session, is established between a first networked node associated with the customer and a second networked node associated with the designated expert studio.

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 provides a system that facilitates encryption of manifest content based on permutation. During operation, the system partitions, by a computer system, a collection of data into a first set of content objects, wherein a content object is a chunk comprised of a plurality of bytes. The system performs a first permutation function on the first set of content objects to obtain a first set of permuted content objects. The system creates a manifest based on the permuted content objects, wherein a manifest is a content object which indicates a second set of content objects, wherein a respective content object of the second set is a data object or another manifest. The system encodes the first permutation function and the permuted content objects in the manifest, thereby facilitating an authorized entity that receives the manifest to reassemble the manifest contents based on the permutation function.

Abstract: One embodiment provides a system that indicates conditions associated with received content. During operation, the system generates, by a first computing device, an interest message which includes a name, wherein the interest message further includes a verification token which is a hash of a nonce. In response to transmitting the interest message to a second computing device, the system receives a content object message which includes a same name as the name for the interest message. In response to detecting a condition associated with the content object message, the system generates a content object return message which includes the nonce and a same name as the name for the content object message. The system forwards the content object return message to the second computing device, thereby facilitating the second computing device to process the content object return message.

Abstract: One embodiment provides a system that facilitates efficient and secure transportation of content. An intermediate node receives a packet that corresponds to a fragment of a content object message that is fragmented into a plurality of fragments. One or more fragments of the plurality of fragments indicate a unique name that is a hierarchically structured variable-length identifier that comprises contiguous name components ordered from a most general level to a most specific level. The received fragment indicates an intermediate state which is based on a hash function performed on an intermediate state from a previous fragment and data included in the received fragment. In response to determining that the received fragment is a first fragment, the system identifies a first entry in a pending interest table for an interest with a name that is based on a hash of a content object and that corresponds to the first fragment.

Abstract: One embodiment provides a system that facilitates dynamic adjustment of forwarding information in a CCN. During operation, the system receives, by forwarding circuitry, an interest with a name that is a hierarchically structured variable length identifier which comprises contiguous name components ordered from a most general level to a most specific level. The system identifies in a first data structure an entry for one or more name components of the name, wherein the entry includes a list of outgoing interfaces associated with the one or more name components. The system determines network properties in response to forwarding the interest to a first interface of the list. The system reorders the list in order of priority based on the network properties, thereby facilitating the forwarding circuitry to dynamically adjust a likelihood of using a respective interface for forwarding interests associated with the one or more name components.

Abstract: One embodiment provides a system that facilitates a secure encryption proxy in a content centric network. During operation, the system receives, by an intermediate router from a content-consuming computing device, a first interest that includes a first name, signaling information encrypted based on a signaling key, and an inner interest encrypted based on an encryption key. The inner interest includes a name for a manifest that represents a collection of data. The intermediate router does not possess the encryption key.
