Abstract

One embodiment provides a system that facilitates selective encryption of bit groups of a message. During operation, the system determines, by a content requesting device or content producing device, a message that includes a plurality of bit groups, each corresponding to a type, a length, and a set of values, wherein one or more bit groups are marked for encryption, and wherein the message indicates a name that is a hierarchically structured variable-length identifier comprising contiguous name components ordered from a most general level to a most specific level. The system computes a plurality of cipher blocks for the message based on an authenticated encryption protocol. The system encrypts the one or more bit groups marked for encryption based on one or more symmetric keys, wherein the marked bit groups include one or more name components. Subsequently, the system indicates the encrypted bit groups as encrypted.
