Security on data storage and transport are important concerns on cloud computing. Wavefront multiplexing / demultiplexing process (WF muxing / demuxing) embodying an architecture that utilizes multi-dimensional waveforms has found applications in data storage and transport on cloud. Multiple data sets are preprocessed by WF muxing before stored / transported. WF muxed data is aggregated data from multiple data sets that have been “customized processed” and disassembled into any scalable number of sets of processed data, with each set being stored on a storage site. The original data is reassembled via WF demuxing after retrieving a lesser but scalable number of WF muxed data sets. In short, the WF muxed data storage solution enhances data security and data redundancy by, respectively, creating a new dimension to existing security / privacy methods and significantly reducing the storage space needed for data redundancy. In addition, WF muxing / demuxing methods enable a monitoring capability on the integrity of stored data.

A computer system can send a secure request over a named-data network to a remote device by generating an Interest with encrypted name components. During operation, the computer system can receive or obtain a request for data, such as from a local user or from a local application. If the system cannot satisfy the request locally, the system can determine at least a routable prefix and a name suffix associated with the request. The system can generate the secure Interest for the request by determining an encryption key that corresponds to a session with the remote computer system, and encrypts the name suffix using the session encryption key. The system then generates an Interest whose name includes the routable prefix and the encrypted name suffix, and disseminates the Interest over a named-data network to send the request to the remote computer system.
