Transmission Device Using Functional Transformation for Secure Data

Solution Overview

Problem

Existing cryptographic methods for data transmission, such as AES, are increasingly vulnerable to attacks due to advances in computing power, necessitating alternative approaches for secure data packet transmission over communication channels.

Innovation Solution

A data packet is represented by a function term, transformed using a predetermined functional transformation, and transmitted as a communication message, with the transformation and its inverse forming a shared secret between transmission and receiving devices, enabling secure transmission through a communication channel.

Solution Approach 1:

The patent replaces traditional cryptographic algorithms (mechanical/mathematical systems like AES) with a physics-based functional transformation system. The transmission device transforms data packets into function terms using predetermined functional transformations, and the receiving device reconstructs original data using inverse functional transformations. This substitution moves security from computational complexity to mathematical function relationships, making it resistant to attacks based on increasing computing power.

Solution Approach 2:

The patent changes the fundamental parameter of data representation from binary encrypted form to functional mathematical form. By representing data packets as function terms with variables and parameters, and using inverse functional transformations for reconstruction, the system creates a new security paradigm that does not rely on traditional cryptographic key management and is therefore resistant to cryptographic attacks.

Solution Approach 1:

The patent applies preliminary action by pre-defining functional transformations and their inverses before data transmission. The transmission device has a library of predetermined functional transformations stored in memory, and the receiving device has corresponding inverse transformations. This pre-preparation eliminates the need for complex real-time computation during transmission, reducing processing complexity while maintaining security.

Inventive Principle:

Solution Approach 2:

The patent segments the data transmission process into distinct phases: data packet to function term transformation at the transmission device, and function term to data packet reconstruction at the receiving device. This segmentation allows each device to perform simpler, specialized operations rather than handling the entire cryptographic process, thereby reducing individual processing complexity while maintaining overall security.
