Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing information update technologies require multiple communication steps for mutual authentication, leading to increased communication overhead and inefficiency in securely updating information between apparatuses.

Innovation Solution

The proposed method reduces communication steps by executing authentication and information update processing as a series of transactions, using ephemeral keys and encrypting data within a single communication request, thereby eliminating the need for separate authentication and update communications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate authentication and update communications are performed between apparatuses, then secure information update is achieved, but the number of communication transactions increases

Engineering Contradiction:

Improvesecurity of information updateVSAvoidcommunication period

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent combines authentication processing and information update processing into a single integrated transaction. The server performs both authentication of the information processing apparatus and the information update operation in one communication exchange, eliminating the need for separate authentication and update transactions. This merging reduces the total number of communication transactions while maintaining security through the authentication mechanism.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If separate authentication and update communications are performed between apparatuses, then secure information update is achieved, but network load increases

Engineering Contradiction:

Improvesecurity of information updateVSAvoidnetwork load

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent merges authentication and information update operations into a single communication transaction between the information processing apparatus and the server. By combining these two previously separate processes into one integrated transaction, the network load is reduced as fewer communication exchanges are required, while the authentication component ensures security is maintained.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If separate authentication and update communications are performed between apparatuses, then secure information update is achieved, but server load increases

Engineering Contradiction:

Improvesecurity of information updateVSAvoidserver processing efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent integrates authentication processing and information update processing into a single server-side transaction. The server performs both the authentication of the information processing apparatus and the execution of the information update operation in one continuous process, reducing the total number of transactions the server must handle while maintaining security through the authentication step.

Inventive Principle:

Principle #5Merging (Combining)
