Abstract
In one embodiment, a method comprises supplying, by a network node to a peer network node, a randomization seed assigned to the network node for generating a prescribed sequence of pseudorandom numbers according to a prescribed pseudorandom number generation function; encoding each data block having a corresponding position in an ordered sequence of a stream of data blocks, into a corresponding differentially-encoded data block based on applying a product of the corresponding data block and the corresponding pseudorandom number, having the corresponding position in the prescribed sequence, to a corresponding successively-preceding differentially-encoded data block from the prescribed ordered sequence, the data block recoverable solely based on a determined difference between the corresponding differentially-encoded data block and the corresponding successively-preceding differentially-encoded data block relative to the corresponding pseudorandom number; and outputting each differentially-encoded data block in a corresponding packet that identifies the network node and the corresponding position.
