Solution Overview

Problem

Current encryption technologies, including asymmetric and symmetric encryption, fail to provide permanent protection solutions for digital transmissions, especially with the advent of quantum computers that will render asymmetric encryption insecure, and existing solutions do not adequately address the need for reciprocal authentication and secure data transmission between network peers.

Innovation Solution

The implementation of a secure authentication method using arithmetic formulas and tables maintained by network servers and clients to ensure equivalence and perfect forward secrecy, enabling the generation of multiple symmetric encryption keys and establishing secure VPN protocols, while also addressing key management issues and providing protection for IoT devices with limited capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If asymmetric encryption is used to provide secure communication, then trust establishment between parties is improved, but security is worsened because quantum computers will destroy asymmetric encryption

Engineering Contradiction:

Improvetrust establishmentVSAvoidquantum computer vulnerability

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent transitions from asymmetric encryption parameters to symmetric encryption parameters, changing the fundamental cryptographic approach. By using symmetric encryption with shared secrets established through out-of-band channels, the system achieves quantum resistance while maintaining trust establishment capabilities

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces the mathematical complexity mechanism of asymmetric encryption with a simpler symmetric encryption mechanism combined with physical/out-of-band secret sharing. This substitution eliminates vulnerability to quantum computing while preserving security goals

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If symmetric encryption is used for secure communication, then encryption efficiency is improved, but key management complexity increases when communicating with multiple parties

Engineering Contradiction:

Improveencryption efficiencyVSAvoidkey management

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces a secret management service as an intermediary that handles key distribution and management. This service acts as a central coordinator that enables efficient symmetric encryption across multiple parties without requiring each participant to manage complex key relationships independently

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If encryption is used to protect digital transmissions, then data security is improved, but permanent protection is not achieved because encryption only provides temporary protection until decryption technologies catch up

Engineering Contradiction:

Improvedata securityVSAvoidprotection duration

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent establishes shared secrets through out-of-band channels before digital transmission occurs. This preliminary action creates a foundation of trust that is not dependent on the mathematical hardness assumptions that may be broken by future decryption technologies, providing longer-term security validity

Inventive Principle:

Principle #10Preliminary action

4Adaptability or versatility

If de-identified transmissions are used to protect privacy, then anonymity is improved, but authentication difficulty increases

Engineering Contradiction:

ImproveanonymityVSAvoidauthentication

Core Design Contradiction:

Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent separates authentication from identification by using shared secrets for authentication while allowing de-identified communication for the actual data transmission. This segmentation enables both anonymity and authentication to coexist by handling these functions through different mechanisms

Inventive Principle:

Principle #1Segmentation

AI summary

A secure authentication between a network server and a network client. The secure authentication being achieved using server and client table objects only known to the server and client. The server and client table objects maintain equivalency. The server and client table objects have a table label for identifying working server and client table. The server and client table objects contain a label group, a data group, and a time group. The server and client contain a duplicate set of arithmetic formulas. The formulas use data from the table objects to send a solution to a receiving node. The receiving node arithmetically reverses the solution to verify sending node. The receiving node then responds using a different formula and different data from the table objects to verify itself to the original sending node. Once a server and client trust are established additional formula are then used to encrypt data.
