Solution Overview

Problem

Existing inter-device authentication technologies face security vulnerabilities due to crosstalk between signals during multiple authentication processes, which can lead to impersonation attacks and reduced authentication certainty.

Innovation Solution

Implementing a dual authentication process using different wireless communication standards and timing separation for signal transmission and reception between communication devices, where the first authentication process uses a first wireless communication standard and the second process uses a distinct second standard, preventing crosstalk and enhancing security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple authentication processes are performed simultaneously to enhance security, then authentication security is improved, but signal crosstalk occurs between the authentication signals

Engineering Contradiction:
Improveauthentication securityVSAvoidsignal crosstalk
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent applies periodic action by performing authentication processes at different time intervals. The control section transmits and receives authentication signals in sequential time slots rather than simultaneously, eliminating signal crosstalk while maintaining security through multiple authentication rounds. Each authentication process is timed to complete before the next one begins.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The patent segments the authentication process into distinct temporal phases. The first authentication signal transmission/reception is separated from the second authentication signal transmission/reception by timing control, dividing the authentication sequence into non-overlapping intervals that prevent interference while achieving layered security.

Inventive Principle:
Principle #1Segmentation

2Reliability

If multiple authentication processes are performed to improve security, then authentication certainty is enhanced, but process complexity increases

Engineering Contradiction:
Improveauthentication certaintyVSAvoidprocess complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The control section performs preliminary timing setup and signal scheduling before executing multiple authentication processes. By pre-configuring the timing sequence and signal transmission intervals, the system manages complex multi-authentication workflows through automated temporal coordination, reducing the perceived complexity while maintaining high authentication certainty.

Inventive Principle:
Principle #10Preliminary action

AI summary

A communication device provides secure inter-device authentication that ensures certainty of processes. The communication device includes a control section configured to execute a process related to transmission or reception of a first authentication signal and a second authentication signal that are necessary for a first authentication process for authentication between the communication device and another communication device. The control section further controls a second authentication process for different authentication from the first authentication process, and starts a process related to transmission or reception of first information that is necessary for the second authentication process after transmission or reception of the second authentication signal.
