Network Access Point Identity Authentication for Secure Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control methods for secure data networks rely on user identity or role, which are inadequate in ensuring differential security across various network access points, leading to potential data leaks when users access sensitive information from less secure environments.
Innovation Solution
Implementing a system where the network access point identity is validated in conjunction with the user identity, using an identity server to match and authenticate the combination, thereby granting or denying access based on the specific network access point, ensuring secure data network access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If access control is based on user identity or role, then user authentication is simplified, but security is compromised because users can access sensitive information from any network location
Solution Approach 1:
The access control system is segmented into two independent authentication factors: user identity (username/password) and network access point identity (device certificate). This segmentation allows the system to evaluate both the user and the network environment separately, then combine their evaluations to make an access decision, thereby maintaining simplicity while improving security
Solution Approach 2:
A certificate authority (CA) is introduced as an intermediary to issue and manage digital certificates for network access points. This intermediary enables automatic, machine-readable verification of network location trustworthiness, replacing manual security assessments and allowing the system to enforce complex security policies without increasing operational complexity for users
2Reliability
If access control is enhanced to consider network access point, then security is improved by preventing access from untrusted networks, but system complexity increases
Solution Approach 1:
Network access points automatically perform self-identification by presenting their digital certificates to the access control system. The system automatically validates these certificates against the CA's public key and checks the access policy database, eliminating the need for manual security assessments and reducing administrative complexity despite enhanced security requirements
Solution Approach 2:
Digital certificates for network access points are pre-issued and configured before the access control system is deployed. This preliminary action allows the system to automatically recognize and evaluate trusted networks from the outset, avoiding the need for complex real-time security assessments and reducing operational complexity
3Object-affected harmful factors
If differential access control is implemented based on network access point, then data leak risk is reduced, but implementation difficulty increases
Solution Approach 1:
The system changes the security parameter from static user roles to dynamic network location trust levels. By using digital certificate validation, the system automatically determines the trustworthiness of each network access point and applies appropriate access policies, reducing data leak risk while simplifying implementation compared to manual security assessments

AI summary
Systems and methods of authenticating user access based on an access point to a secure data network include a secure data network having a plurality of a network access points serving as entry points for a user to access the secure data network using a user device. The user is associated with a user identity, each network access point with a network access point identity. The user uses a user device to send an access request, requesting access to the secure data network, to the network access point, which then sends an authentication request to an identity server. The identity server processes the authentication request, by validating the combination of the user identity and the network access point identity, and responds with an authentication response, granting or denying access, as communicated to the user device via an access response.
