摘要
One embodiment provides a system that facilitates mutating and caching content in a CCN. During operation, the system receives, by an intermediate node, a content object that indicates an encrypted payload, a signature, and a parameter for a group to which the content object belongs, wherein the content object includes a name that is a hierarchically structured variable length identifier which comprises contiguous name components ordered from a most general level to a most specific level. The system re-encrypts the content object based on the encrypted payload and the parameter to obtain a new encrypted payload and a new signature, wherein re-encrypting is not based on a private key or a public key associated with the encrypted payload. The system transmits the re-encrypted content object to a client computing device, thereby allowing the client computing device to decrypt the re-encrypted content object and verify the new signature.
