Aggregate Signing Of Data In Content Centric Networking


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.
