摘要:Residue Number System (RNS) is a non-weighted integer system that can speed up arithmetic operations, Since the operations are done in parallel with no carry. Redundant RNS (RRNS) is a trait of RNS provides reliable communication in networks which can detect the errors and correct them. Also this system can be used in cryptography algorithms because it is fast. Here, it is the suggested RRNS to be used in a Multi-Level system to achieve both reliable and secure connections.
