Mobile Access Control Server for Secure Encrypted Data Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Internet communication systems, such as those using the X.509 standard and SSL/TLS, lack effective mechanisms for authenticating users and controlling access to data services, especially in mobile devices, which are vulnerable to 'man-in-the-middle' attacks and require secure access to data services while moving.
Innovation Solution
A mobile access control server system that manages access to data services by providing or denying certificates and session keys to mobile devices, ensuring secure communication through HTTPS, and controlling access independently of the device's location or access point, using a networked system that includes a mobile access control server, content server, and certificate authority.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption and secure protocols are used, then communication security is improved, but vulnerability to man-in-the-middle attacks and spoofing sites persists
Solution Approach 1:
The patent introduces a certificate authority (CA) as an intermediary that issues digital certificates to authenticate users and servers. This mediator verifies identities and provides cryptographic proof, preventing man-in-the-middle attacks by ensuring that communicating parties can verify each other's true identity through trusted certificates rather than relying solely on encryption protocols.
Solution Approach 2:
The patent implements preliminary authentication through digital certificates before secure communication begins. The CA verifies user identities and issues certificates in advance, so that when communication starts, both parties already have verified credentials. This preliminary action prevents spoofing attacks by ensuring authentication occurs before the secure channel is established.
2Reliability
If X.509 certificates and SSL are used for authentication, then identity verification is improved, but the system does not address validation effort or global meaning of information
Solution Approach 1:
The patent enables mobile devices to autonomously validate certificates and perform authentication operations locally using cryptographic libraries. The device itself checks certificate chains, verifies digital signatures, and manages security credentials without requiring manual validation or complex centralized verification processes, thereby reducing overall system complexity while maintaining strong identity verification.
3Adaptability or versatility
If mobile devices access data services over the Internet, then accessibility and mobility are improved, but security vulnerabilities increase due to non-physical communication channels
Solution Approach 1:
The patent applies preliminary anti-action by pre-establishing trusted cryptographic relationships through certificate issuance before mobile devices access data services. The CA pre-issues certificates to legitimate users and servers, creating a foundation of trust that actively counteracts eavesdropping and interference attempts. When communication occurs, this pre-established trust relationship immediately prevents unauthorized interception or manipulation.
Data Source
AI summary
A networked system for controlling the mobile access to a data service, which may provide encrypted data, is presented. The system may include a mobile device and a mobile access control server, which controls the mobile device's access to the data service by controlling the access information required to access the data service. The system may also include a content server that provides the data service, a certification authority, and a network for enabling communication among the components of the system. To access encrypted data services, the mobile device communicates an access request to the mobile access control server, which determines whether access should be granted, and provides access information to the mobile device, enabling the mobile device to establish encrypted communication with the content server and/or to decrypt the encrypted data provided by the data service via the content server.
