Trusted Component Key Representation for Secure Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current key-based security systems are vulnerable to hacking and misuse, as they rely on exact matches of alphanumeric keys, leading to unauthorized access and breaches in sensitive systems, including financial transactions, personal records, and military systems.
Innovation Solution
A process that links a key to a component by forming a unique representation of the key using environmental variables, which is then tested to ensure it is not statistically duplicative, thereby preventing fraud and hacking attempts, and allowing only the legitimate component to access encrypted digital assets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a key-based access control system is used, then ease of operation is improved, but security reliability deteriorates due to hacking and unauthorized access
Solution Approach 1:
The patent introduces a trusted component as an intermediary between the key and the access control system. This component securely stores the key and performs cryptographic operations, preventing direct exposure of the key while maintaining access control functionality. The intermediary architecture resolves the contradiction by enabling easy key-based operation while ensuring security through the trusted component's protection mechanisms.
Solution Approach 2:
The patent replaces the traditional mechanical key-matching system with a cryptographic system using public key infrastructure and digital signatures. Instead of direct key comparison, the system uses cryptographic proofs and trusted component verification, substituting the vulnerable mechanical authentication process with mathematically secure cryptographic operations that prevent hacking and unauthorized access.
2Reliability
If encryption is used to protect digital assets, then security reliability is improved, but access control complexity increases due to key management requirements
Solution Approach 1:
The patent extracts the key management complexity from the access control system by placing keys inside a trusted component. The key is taken out of the general system and isolated within a secure environment, which protects it from exposure while simplifying the external interface. This extraction resolves the contradiction by maintaining strong encryption security while reducing access control complexity through a simplified verification process.
Solution Approach 2:
The trusted component provides self-service functionality by automatically managing key storage, cryptographic operations, and access verification without requiring external key management infrastructure. The component handles all complex key operations internally, eliminating the need for complex external key management systems while maintaining high security reliability through its self-contained secure operations.
3Ease of manufacture
If traditional key validation is used, then ease of manufacture is improved, but security against fraud deteriorates due to key duplication and theft
Solution Approach 1:
The patent implements asymmetric cryptography where the private key remains secret within the trusted component while the public key is freely distributed. This asymmetric architecture prevents fraud because the public key cannot be used to derive the private key or create valid authentication proofs. The asymmetry resolves the contradiction by enabling easy manufacturing and distribution of public keys while providing strong protection against key theft and duplication through mathematical one-way functions.
Data Source
AI summary
A process of linking a key to a component is disclosed herein. In various aspects, the key may be a password, hash, key, encryption key, decryption key, seed value, unlock code, or other alphanumeric identifier, and the component includes a computer in networked communication, and may further include a specific user of the computer. The process may include the step of identifying a component using environmental variables associated with the component, and the process step of forming a representation of the key unique to the component. The representation is tested to determine that the identified component is the source of the representation, in various aspects. Accordingly, the process may include the step of testing the representation against previous representations thereby determining the representation is not statistically duplicative of previous representations, and the process may include the step of testing the representation against possible representations from the component where the possible representations are unique to the component.
