Solution Overview

Problem

Wireless communication networks face cumbersome authentication processes and inefficient slice selection procedures for secure user access to network slices, and they fail to effectively utilize distributed ledgers and content-addressing for data services.

Innovation Solution

Implementing content-addressing and distributed ledgers by generating a content-address from a data set, encrypting it with a system key, transferring it to a wireless communication device for decryption and re-encryption with a user key, and retrieving the data set using the decrypted content-address to deliver wireless data services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional authentication processes and slice selection procedures are used, then secure user access is achieved, but the process becomes cumbersome and inefficient

Engineering Contradiction:

Improvesecure user accessVSAvoidauthentication process

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent extracts the authentication and slice selection functionality from the traditional multi-step network protocol exchange and implements it as a self-contained content-addressable storage system. The user device independently generates content addresses from its identity and service requirements, eliminating the need for complex network-side authentication procedures while maintaining security through cryptographic hashing.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The user device performs self-authentication by generating content addresses from its own identity and service requirements. The device independently computes the content address without requiring network-side verification, enabling self-service authentication that is both secure and efficient. The network simply retrieves service configuration using the content address without performing complex authentication logic.

Inventive Principle:

Principle #25Self-service

2Productivity

If distributed ledgers and content-addressing are implemented, then authentication efficiency is improved, but system complexity increases

Engineering Contradiction:

Improveauthentication efficiencyVSAvoidsystem structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The content-addressable storage system serves multiple functions simultaneously: it acts as an authentication mechanism, a slice selection system, and a service configuration repository. The content address generated from user identity and service requirements universally identifies both the user and their service preferences, eliminating the need for separate authentication and service selection systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Instead of the network authenticating the user through complex protocol exchanges, the inversion approach has the user device generate its own authentication credentials (content addresses) that the network simply verifies and uses for service retrieval. This inverts the traditional authentication paradigm, placing the computational burden on the user device while simplifying network operations.

Inventive Principle:

Principle #13The other way round (Inversion)

3Speed

If content-addressing is used to retrieve data sets, then data access speed is improved, but cryptographic processing overhead increases

Engineering Contradiction:

Improvedata access speedVSAvoidcryptographic processing

Core Design Contradiction:

SpeedVSUse of energy by moving object

Solution Approach 1:

The user device performs the cryptographic hashing operation in advance to generate the content address before any data retrieval occurs. This preliminary action allows the network to directly retrieve the service configuration data using the pre-computed content address without performing any cryptographic operations during the actual data access, thus achieving fast data retrieval while concentrating cryptographic overhead in a single upfront operation.

AI summary

A wireless communication system delivers a wireless data service to a wireless communication device using content-addressing. The wireless communication system generates a content-address from a data set. The wireless communication system stores the content-address in association with the data set. The wireless communication system encrypts the content-address with a system key and transfers the encrypted content-address to the wireless communication device. The wireless communication device decrypts the encrypted content-address with a user key to obtain the content address. The wireless communication device re-encrypts the content-address with the user key. The wireless communication system receives the re-encrypted content-address from the wireless communication device and decrypts the re-encrypted content-address with the system key to obtain the content-address. The wireless communication system retrieves the data set from the memory circuitry with the decrypted content-address. The wireless communication system delivers the wireless data service to the wireless communication device based on the retrieved data set.
