Electronic transmission/authentication of texts involves secure autonomous functional module with key bank into which duplicate key is fed in controlled manner

摘要

The method involves providing subscribers with identifiers, asymmetrical crypto algorithm with a key and an asymmetrical crypto algorithm with a public key. An instance worthy of verification has a symmetrical algorithm and key. An autonomous functional module is externally inaccessible and contains a key bank into which a duplicate key is entered in a controlled manner. An Independent claim is also included for a method of encoded storage and reproduction of a random number and key and for a symmetrical crypto algorithm.
