Encrypted User Certificate for Secure Remote Storage Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication methods for remote access to devices, particularly for service personnel accessing storage media, are inefficient and inconvenient, requiring multiple steps and network transitions, and lack effective verification of access levels.
Innovation Solution
A method involving a first client providing personal information to a server, receiving an encrypted user certificate, and using it to obtain remote access information from a second server, facilitating secure and efficient remote access based on verified credentials across networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional multi-step authentication is used for remote service access, then security verification is achieved, but process efficiency and user convenience deteriorate due to multiple network transitions and steps
Solution Approach 1:
The system performs authentication actions in advance by issuing certificates to service users before they need remote access. The certificate authority signs the service user's public key and attributes in advance, creating a pre-validated authentication credential that can be quickly presented later without requiring multi-step verification at the moment of access.
Solution Approach 2:
The invention introduces a certificate authority as an intermediary that issues digital certificates to service users. This certificate acts as a mediator between the service user and the service interface, allowing the service interface to verify authentication through certificate validation rather than requiring direct multi-step interaction between the service user and multiple authentication systems.
2Reliability
If traditional authentication requiring multiple network transitions is used, then comprehensive verification is achieved, but user convenience deteriorates
Solution Approach 1:
The invention extracts the authentication credential (certificate) from the complex multi-step authentication process and consolidates it into a single portable object. The certificate contains all necessary verification information (public key, attributes, signature) that can be presented in one step, eliminating the need for users to navigate multiple authentication screens or networks.
Solution Approach 2:
The certificate serves multiple functions simultaneously: it authenticates the service user's identity, verifies their access level attributes, and enables secure communication. This multi-functional credential replaces multiple separate authentication mechanisms, allowing comprehensive verification through a single universal credential.
3Reliability
If encrypted user certificates are implemented for cross-network authentication, then security is improved, but system complexity increases
Solution Approach 1:
The system creates a digital copy of the service user's authentication credentials in the form of a certificate that can be replicated and transmitted across networks. The certificate is a copy of the essential authentication information (public key, attributes) that has been signed by the certificate authority, allowing verification without requiring the original private key or complex authentication infrastructure at the service interface.
Data Source
AI summary
A pair of servers are employed to provide a secure low-overhead authentication of a user. A certificate server of the pair receives personal information of the user from a first client over a first network and provides an encrypted user certificate to the first client over the first network, wherein the encrypted user certificate includes an encryption of one or more personal attributes of the user corresponding to the set of personal information. A device control server receives the encrypted user certificate from a second client over a second network and provides remote access information to the second client over the second network, wherein the remote access information facilitates remote access to a device by the user over the second network based in response to a verification by the device control server of the encrypted user certificate.
