A new method for secure transmission is disclosed, called the Reference Matrix (R Matrix). It provides a new technique for encoding a message over public switched networks using a spatial transformation. It is superior to encryption in that 1) no human intervention is allowed, 2) there is no key management involved (thus, no costs of key generation, maintenance, or distribution are incurred), and 3) it can be built on a chip for easy and inexpensive installation and use by front-end networking computers, to computerized branch exchanges. Its disadvantage is the use of more than one transmission circuit for a single message. Fig. 1 summarizes the use of the R Matrix compared to several other security mechanisms.
