Disclosed are methods, systems, devices, apparatuses, computer-/processor-readable media, and other implementations for data communication in which data is divided into multiple data blocks, with each of the multiple data blocks including a portion of a respective at least one other of the multiple data blocks to produce multiple corresponding resultant data blocks. Additionally, at least one validation code is generated based on the multiple corresponding resultant data blocks. At least the multiple corresponding resultant data blocks and the at least one validation code are communicated to a remote device.
