摘要
There is described a multimodule data processing system with N fully interconnected data processing modules for executing a Dispersed Joined Communication method according to a K-level nested and level-wise compartimentalized encoding, broadcasting and decoding operation. This allows for protecting against at most T maliciously operating modules, wherein . At level K all said N modules are situated in a single compartment. At level k=1 for any extant message in any actual module such extant message is broadcast to all modules present in that message's compartment. For any level said operation previously comprises for any extant message generating therefrom symbols according to a T-symbol error correcting encoding and within that message's actual compartment transmitting each of such n symbols as messages to a respective different module. Those different modules together constitute a next lower-level compartment for therein executing said operation according to next lower level k-1. At least one level k1 comprises a data reducing encoding, or alternatively transmitting to less than all modules available for transmission thereto within the actual compartment. After such K rounds of information transmission said method comprises exclusively single-module-based and in such single module compartment-wise decoding according to successive levels (1..K) of any message or symbol present in the actual module.
