One embodiment provides a system that facilitates redistribution of content objects with a different name without requiring re-computation of the original authentication information. During operation, the system determines, by a content producing device, an original manifest which indicates at least an original name associated with a content object, wherein the name 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 renames the content object with a new name. The system also creates a new manifest which indicates the new name, wherein the new manifest includes original authentication information associated with the original manifest.

One embodiment provides a system that facilitates routers in verifying content objects in a cost-effective manner by aggregating content objects into a secure content catalog. During operation, a client computing device receives a secure content catalog, which indicates a set of content objects and their corresponding digests. The catalog is digitally signed with the private key of a producer of the catalog. The client computing device constructs an interest for a content object, where the interest indicates a name for the content object and the corresponding digest for the content object, which is based on the secure content catalog. The name for the request content object is a hierarchically structured variable length identifier (HSVLI) which comprises name components ordered from a most general level to a most specific level.

The a user interface (UI) residing in a mobile environment, which has a possibility of indicating after reading each message whether or not the message is divergent from the normal/general level as to the importance of the message. Advantageously, the user does not need to do the indication every time when reading the mail. In the interface, after a given mail has been read (or a part of the given mail has been read), there occurs a possibility to choose between two alternatives: interesting or non-interesting. Advantageously, there is not required other extra work from the user. Gradually, a mail agent collects information about what kind of mail the user prefers and does not prefer. The result will be a prearranged list by preference in the incoming mail. Any mail similar to the ones previously indicated as important will appear first to the user. The applied algorithm in the methods and systems is based on statistical analysis of the linguistic contents of the mail.

One embodiment provides a system that facilitates forwarding of packets with variable length names. During operation, the system receives a packet with 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 performs a longest prefix match lookup by selecting an entry from a first data structure of entries. The entries indicate a name component, forwarding information for the name component, and a plurality of entry identifiers that chain an entry to another entry. If a size of the name component is less than or equal to a predetermined threshold, the system selects an entry based on the name component. If the size is greater, the system selects an entry based on a compressed key which can be a hash of the name component. The system also resolves collisions associated with the selected entry.

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.

One embodiment provides a system that delegates signature production in a CCN. During operation, a first content producing device monitors content objects created by a second content producing device. A content object can be identified by 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 first device retrieves the content objects and authenticates a message authentication code for each content object based on a key shared by the first and second device. The first device creates a manifest with a name and a content object hash value for each content object, produces a digital signature for the manifest based on a private key of the first device, and includes the digital signature in the manifest, thereby delegating signature production to the first device for content objects created by the second device.
