Abstract
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.
