Self-Escrow Credential Unlocking for Secure Program Domain Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing key escrow systems are vulnerable to hacking, misuse, and lack secure mechanisms for ensuring that extraordinary access to program domains is granted only to authorized parties under controlled conditions, raising concerns about privacy and due process.
Innovation Solution
A method and apparatus for exclusive self-escrow that uses mutual authentication between a third-party provider (TPP) and a locked device owner's program domain (DO-PD) through the use of exclusive self-escrow credentials stored within the DO-PD, ensuring that any attempt to unlock the domain is authorized and recorded for the owner's knowledge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If key escrow systems are used to provide extraordinary access to program domains, then access can be granted to authorized parties, but the system becomes vulnerable to hacking, theft, and misuse of stored credentials
Solution Approach 1:
The patent extracts the escrow credential storage from external centralized databases and relocates it within the locked program domain itself. The escrow credential is stored in a secure area of the program domain's memory, eliminating the vulnerability of external database storage while maintaining the ability to grant extraordinary access to authorized parties.
Solution Approach 2:
The patent introduces a mutual authentication mechanism as an intermediary between the third party requesting access and the locked program domain. This authentication process verifies the identity and authorization of the third party before releasing the escrow credential, preventing unauthorized access while enabling legitimate extraordinary access requests.
2Ease of operation
If a single key unlocks many program domains in key escrow systems, then access management is simplified, but the accidental release of the key compromises many devices simultaneously
Solution Approach 1:
The patent segments the escrow credential storage by program domain, with each program domain maintaining its own independent escrow credential in its secure memory area. This segmentation ensures that a compromise or accidental release of credentials in one program domain does not affect other domains, preventing mass compromise while maintaining simplified access management through the same escrow mechanism.
3Extent of automation
If third parties hold escrow credentials externally, then access control is centralized, but privacy rights and due process are compromised through unauthorized surveillance
Solution Approach 1:
The patent inverts the traditional key escrow model by moving the credential storage from external centralized authority to the locked program domain itself. The program domain holds its own escrow credential internally, and mutual authentication verifies third-party authorization before access is granted. This inversion eliminates external surveillance capabilities while maintaining automated access control, thereby protecting privacy rights and due process.
Data Source
AI summary
A method and apparatus provides for securely unlocking a locked program domain by a third party wishing to gain extraordinary access to the program domain by a third party. The third party and the program domain are mutually authenticated using exclusive self-escrow of credentials that are generated, revealed, or stored within the program domain. Multiple third parties that are required for unlocking the program domain may also be authenticated prior to unlocking the program domain. The method and apparatus provides extraordinary access without the use of backdoors or having the program domain provide credentials to third parties.
