Electronic Device Secure Access via Centralized Key Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in secure remote access, as managing individualized security measures for multiple devices is costly and burdensome, and existing key-based systems are inefficient for granting and denying access on a device-by-device basis.
Innovation Solution
An electronic device generates a password using a random number, encrypts it with a public key component, and provides it to a client device, which submits the encrypted password to a private key server for decryption, allowing secure access over an encrypted connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individualized security measures are implemented for multiple electronic devices, then security reliability is improved, but device complexity and management burden increase
Solution Approach 1:
The patent implements a universal authentication system where a single private key server provides authentication services for multiple electronic devices. Instead of configuring individual security measures on each device, the system uses a centralized authentication mechanism that handles security for all devices uniformly. The electronic device, client device, and private key server work together as a multi-functional system that provides device-specific security through a universal protocol.
Solution Approach 2:
The patent introduces a private key server as an intermediary between electronic devices and client devices. The private key server receives authentication requests, verifies credentials, and grants or denies access accordingly. This intermediary simplifies the authentication process by centralizing security management, eliminating the need for complex individualized security configurations on each electronic device.
2Reliability
If preinstalled security measures are deployed on each electronic device, then security reliability is improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The patent extracts the complex security management functionality from individual electronic devices and relocates it to a centralized private key server. The electronic devices themselves remain simple, lacking preinstalled security measures or authentication logic. Instead, they rely on the private key server to provide authentication services, thereby reducing manufacturing complexity and cost while maintaining security reliability.
Solution Approach 2:
The authentication system operates autonomously through the interaction of the electronic device, client device, and private key server. The private key server automatically verifies credentials and grants or denies access without requiring manual security configuration on each electronic device. This self-service mechanism eliminates the need for costly preinstalled security measures while ensuring reliable authentication.
3Reliability
If existing key-based systems are used for access control, then security is provided, but efficiency in granting and denying access deteriorates
Solution Approach 1:
The patent implements preliminary authentication where the client device obtains an unencrypted password from the private key server before attempting to access the electronic device. The private key server pre- verifies the client's credentials and provides authenticated credentials in advance. This preliminary action streamlines the access control process, allowing efficient granting or denying of access without compromising security.
Solution Approach 2:
The patent replaces traditional mechanical key-based access control systems with an electronic authentication system. Instead of physical keys or complex cryptographic key exchanges, the system uses electronic password transmission and verification through the private key server. This substitution improves efficiency by enabling rapid automated authentication while maintaining strong security controls.

AI summary
Disclosed is an electronic device that selects a password and encrypts it utilizing a public key of a public/private encryption key pair. The electronic device then provides the encrypted password to a client device when an access request is received from the client device. The client device proceeds to obtain an unencrypted version of the password by submitting the encrypted password to a private key server (which utilizes the private key of the public/private encryption key pair to decrypt the password) and receiving the decrypted password in return. The client device then returns the password to the electronic device which, upon receiving the decrypted password, allows access from the client device. The device generates the password once during operation or each time an access request is received.
