Smartphone Security Authentication via Segmented Activation Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smartphones can access security authentication devices without proper authentication, leading to security vulnerabilities due to shared communication protocols, necessitating a method to ensure secure access control.
Innovation Solution
A method involving the generation and registration of an activation code using a block cipher symmetric key operation, which includes a first and second cryptic code, is used to authenticate Smartphones accessing security authentication devices, limiting unauthorized access and ensuring secure device search and access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Smartphones use the same communication protocol as security authentication devices, then ease of operation is improved, but security is worsened due to unauthorized access vulnerability
Solution Approach 1:
The patent segments the authentication process into two distinct parts: a public communication protocol layer that enables ease of operation, and a private activation code layer that ensures security. The activation code is divided into first and second cryptic codes that are separately managed, creating a segmented defense mechanism that maintains both accessibility and security.
Solution Approach 2:
The patent introduces an activation code as an intermediary authentication element between the Smartphone and the security authentication device. This intermediary mechanism (comprising first and second cryptic codes) mediates the authentication process, allowing legitimate access while blocking unauthorized attempts without compromising the underlying communication protocol compatibility.
2Reliability
If activation code authentication is implemented, then security is improved, but device complexity increases due to additional authentication steps
Solution Approach 1:
The patent applies preliminary action by pre-distributing the first cryptic code to the Smartphone and the second cryptic code to the security authentication device before actual authentication occurs. This preliminary distribution of authentication components simplifies the real-time authentication process, as the complex cryptographic setup is completed in advance during device registration.
Solution Approach 2:
The patent uses copying by distributing identical copies of the authentication system components (first cryptic code to Smartphone, second cryptic code to security device) across multiple devices. This copying approach allows the authentication mechanism to be replicated without increasing the complexity of each individual device, as the complexity is distributed across the system rather than concentrated in one location.
3Reliability
If activation code password authentication is required, then security is improved, but ease of operation is worsened due to additional password input requirements
Solution Approach 1:
The patent applies local quality by implementing different authentication requirements for different scenarios: the first cryptic code is used for initial device identification (simpler operation), while the second cryptic code activated by password input provides enhanced security for sensitive operations. This localized quality of authentication ensures that users experience simplicity when appropriate while maintaining security when needed.
Data Source
AI summary
A method for registering a Smartphone when accessing security authentication device and a method for access authentication of a registered Smartphone are provided. When a Smartphone based application searches for a device and attempts an access to the found device, the search and access for the device is limited according to a result of authentication using an activation code.
