摘要： One embodiment provides a system that facilitates efficient key retrieval by using key catalogs in a content centric network. During operation, the system generates, by a client computing device, a first interest for a key indicated in a signed key catalog. In response to receiving the key, the system verifies the received key by determining that a hash of the received key matches a hash of the key as indicated in the catalog based on a name for the received key. The system generates a second interest for a content object, wherein a name for the second interest includes a name prefix associated with the key as indicated in the catalog, wherein the first interest is transmitted before or concurrent with transmitting the second interest. In response to receiving the content object, the system verifies the received content object based on the key.

摘要： One embodiment provides a system that facilitates a single interface for file I/O and network communication. During operation, the system receives from a local application a first command to create content. The first command includes a content name and access control information that indicates how the content may be accessed. The content name is a hierarchically structured variable length identifier that includes contiguous name components ordered from a most general level to a most specific level. The system creates a first manifest which is a content object that indicates a set of content objects by a name and a digest. The first manifest name is the content name corresponding to the first command, and access to the manifest is based on the access control information included in the first command. The system transmits to the local application the first manifest and an indicator of success for creating the first manifest.

摘要： One embodiment provides a transport-framework system that facilitates command messages to be communicated in a layer-agnostic manner. During operation, the system generates, by a component of a stack of communication modules, a first command message for a target entity. The first command message includes a name unique to the target entity, and the stack does not require a respective communication module to communicate only with a layer above or below thereof The component sends the first command message to the target entity by inserting the first command message into a queue corresponding to the component. The component can also receive a second command message from a sending entity via a queue corresponding to the sending entity, and the second command message includes a name unique to the component. This facilitates command messages to be communicated in a layer-agnostic manner.

摘要： A data verification system facilitates verifying whether a CCN Content Object is authentic or trustworthy on behalf of an application. During operation, the system can obtain a stack requirement for a custom transport stack, which specifies at least a description for a verifier stack component that verifies a Content Object using a key identifier (KeyID) associated with a publisher. The system instantiates the verifier stack component in the custom stack, and can use the custom stack to obtain a verified Content Object. While using the custom stack, the system can push, to the custom stack, an Interest that includes a name for a piece of content and includes a KeyID associated with a content producer. The system then receives, from the custom stack, a Content Object which the verifier stack component has verified is signed by the content producer associated with the KeyID.

摘要： One embodiment provides a system that facilitates efficient and transparent encryption of packets between a client computing device and a content producing device. During operation, the system receives, by a content producing device, an interest packet that includes a masked name which corresponds to an original name, wherein the original name is a hierarchically structured variable length identifier that includes contiguous name components ordered from a most general level to a most specific level. The system obtains the original name based on the masked name. The system computes a symmetric key based on the original name and a generated nonce. The system generates a content object packet that corresponds to the original name and includes the masked name, the nonce, and a payload encrypted based on the symmetric key, wherein the content object packet is received by a client computing device.

摘要： 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.

摘要： An identity management and initialization scheme, along with a naming scheme for a transport stack and its components, facilitates directly addressing each component in the transport stack. During operation, the system receives, by a forwarder, a packet that corresponds to an interest, where the interest includes a name. In response to determining that the interest is destined for a component of a stack of communication modules, the forwarder sends the interest to the destined component based on the name for the interest, where the stack does not require a respective communication module to communicate only with a layer above or below thereof. In response to determining that the interest is not destined for a component of the stack, the forwarder sends the interest to a network element based on the name for the interest. This facilitates directly addressing individual components of the stack.

摘要： One embodiment provides an access-control framework for publishing and obtaining a collection of encrypted data in encrypted form. During operation, a content consumer can obtain a Manifest object for a data collection, such that the Manifest includes references to a set of encrypted Content Objects of the data collection, and includes one or more Access Control Specifications (ACS) that each specifies a decryption protocol for decrypting one or more Content Objects of the data collection. The consumer can disseminate Interest messages to receive encrypted Content Objects listed in the Manifest over an Information Centric Network (ICN). The client can also obtain, from the Manifest, an ACS associated with a respective encrypted Content Object, and decrypts the respective encrypted Content Object using the decryption protocol specified in the ACS.

摘要： One embodiment provides a system that facilitates direct seeking of the ordered content of a manifest based on external metadata. During operation, the system determines, by a content producing device, a root manifest, wherein a manifest indicates a set of content objects and their corresponding digests, wherein a respective content object is a data object or another manifest, and is associated with a name that is a hierarchically structured variable length identifier (HSVLI) which comprises contiguous name components ordered from a most general level to a most specific level. The system generates an index associated with the root manifest, wherein the index allows the set of content objects indicated in the root manifest to be searched and accessed directly, thereby facilitating a content consumer to seek to a desired location in the content represented by the root manifest.
