Cryptography based on new core with source key and implementable key involves converting source key of any length and structure to implementable key of fixed length, structure

摘要

The method involves the use of a new core within any purposeful surface. A source key of any length and structure is converted to an implementable key of fixed length and structure by a single conversion so that encoding and encoding can then be carried out at a rate approximating to simple data transmission while the security level is simultaneously very high. AN Independent claim is also included for the following: a surface with the characteristic of a symmetrical cryptic method and a surface with the characteristic of an asymmetrical cryptic method.
