1. A computer system to facilitate key retrieval, comprising: a processor; a storage device coupled to the processor and storing instructions that when executed by a computer cause the computer to perform a method, the method comprising: generating, by a client computing device, a first interest for a key indicated in a signed key catalog, wherein the key indicated in the signed key catalog is embedded within a key set such that a request for another key within the signed key catalog functions as the first interest, wherein the signed key catalog comprises a link to a chunked key stream partitioned based on a chunking protocol; in response to receiving the key as a received key, verifying 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; generating 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; and in response to receiving the content object, verifying the received content object based on the key.
