Cryptography Chip Identity Verification Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cryptographic keys are vulnerable to loss or compromise, leading to security risks and economic losses, as existing methods lack effective identity verification mechanisms to control access to encryption keys.
Innovation Solution
A cryptography chip with integrated storage for key and identity information verifies the identity of users requesting cryptographic operations, ensuring that only authorized users can perform operations using stored cryptographic keys, and preventing unauthorized access by rejecting unverified requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cryptographic keys are stored for use in cryptographic operations, then cryptographic functionality is enabled, but the keys become vulnerable to loss or compromise
Solution Approach 1:
The system segments the cryptographic system into separate components: a cryptography chip that stores and protects cryptographic keys, and a separate identity verification mechanism. This segmentation isolates the keys in a secure environment while enabling controlled access through identity verification, thus maintaining cryptographic functionality while reducing key compromise risk.
Solution Approach 2:
The patent introduces an identity verification mechanism as an intermediary between the user and the cryptographic keys. This intermediary layer verifies user identity before allowing access to cryptographic operations, preventing unauthorized key usage even if the key storage is compromised. The intermediary controls and limits access to the cryptographic functionality.
2Object-affected harmful factors
If access control mechanisms are added to protect cryptographic keys, then security is improved, but system complexity increases
Solution Approach 1:
The patent merges the identity verification functionality directly into the cryptography chip, combining what could be separate systems into a single integrated device. This merging reduces overall system complexity while maintaining security, as the identity verification and key protection work together within the same secure hardware environment.
Solution Approach 2:
The cryptography chip performs self-verification of user identity and automatically controls access to cryptographic operations without requiring external complex verification systems. The chip manages its own security protocols, key protection, and access control internally, reducing the need for additional external security infrastructure.

AI summary
Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for performing cryptographic operations subject to identity verification. One of the methods includes receiving, by a cryptography chip, a request to perform a requested cryptographic operation from a client including client identity information, wherein the cryptography chip includes a processing resource that performs cryptographic operations and a storage resource that stores key information used in the cryptographic operations, and identity information associated with clients that are permitted to request cryptographic operations; determining, by the cryptography chip, that the client identity information is associated with one of the clients that are permitted to request cryptographic operations; and performing, by the cryptography chip, the requested cryptographic operation based on the key information stored in the storage resource.
