Secure Device Conditional Cryptographic Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for secure transfer of cryptographic data, such as cryptocurrencies and NFTs, rely on third parties or smart contracts, which introduce counterparty risk, complexity, and potential for errors or theft, and do not effectively prevent replay attacks or ensure compliance.
Innovation Solution
A peer-to-peer system that uses secure devices to facilitate conditional transfer of cryptographic data through a proposal process, attestation, and secure channel establishment, ensuring compliance and reducing counterparty risk by deleting cryptographic data upon transfer completion and utilizing reputation systems for non-performance tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If third parties or smart contracts are used for secure transfer of cryptographic data, then security and trust are improved, but device complexity and counterparty risk increase
Solution Approach 1:
The patent extracts the trust verification function from external third parties or smart contracts and embeds it directly into the secure device through attestation mechanisms. The device autonomously verifies the identity and credentials of communication partners using embedded security modules, eliminating the need for external arbitration while reducing complexity.
Solution Approach 2:
The secure device performs self-verification and mutual authentication with other devices through cryptographic attestation. Each device independently verifies the other's identity and security credentials without requiring external third-party intervention, enabling autonomous secure transfers while reducing system complexity.
2Reliability
If third parties or smart contracts are used for secure transfer of cryptographic data, then security and trust are improved, but transaction time and efficiency worsen
Solution Approach 1:
The patent implements preliminary attestation and credential verification during device initialization and pairing phases. Security credentials are pre-established and cached in secure memory, allowing rapid verification during actual transfers without time-consuming real-time authentication, thus reducing transaction time while maintaining trust.
Solution Approach 2:
Devices perform autonomous mutual authentication using pre-established cryptographic credentials, eliminating the need for time-consuming interactions with external third parties or smart contract executions. The self-service verification process significantly reduces transaction time while maintaining security.
3Reliability
If cryptographic data is retained for verification purposes, then compliance and security monitoring are improved, but security risk increases due to potential theft or unauthorized access
Solution Approach 1:
The patent implements different retention policies for different types of data. Sensitive cryptographic secrets are stored in secure enclaves with restricted access and automatic deletion after use, while non-sensitive verification metadata is retained for compliance. This localized quality differentiation reduces theft risk while maintaining compliance.
Solution Approach 2:
The system automatically deletes cryptographic data after verification completion or upon detecting suspicious activity, while maintaining audit trails through secure logging. The ability to discard sensitive data and recover only essential verification information reduces exposure to theft while preserving compliance capabilities.
4Reliability
If external systems like blockchain servers are used for transfer verification, then trust and security are improved, but system complexity and cost increase
Solution Approach 1:
The patent extracts the verification function from external blockchain servers and implements it locally within secure devices using cryptographic attestation and mutual authentication. This extraction eliminates dependency on complex external infrastructure while maintaining trust through device-intrinsic security mechanisms.
Solution Approach 2:
Devices perform self-verification of transfer authenticity through cryptographic proof and mutual authentication, eliminating the need for external blockchain server intervention. This self-service approach reduces system complexity and cost while maintaining trust through autonomous security verification.

AI summary
Secure conditional transfer of cryptographic data allows transfer of cryptographically-based data from one party to another while mitigating failure of a counterparty to perform. A first party uses a first device to send a proposal to a second party's device. If the proposal is accepted, it is signed by the second device. A secure channel is established between the devices that also attests to their compliance during processing. Transaction identifiers associated with the proposal and other information are exchanged. Once exchanged, the first device creates and sends first transfer data (that may be signed) to the second device. The second device receives and determines the first transfer data is valid. In response, the second device creates and sends second transfer data (that may be signed) to the first device. If a communication or other failure prevents reciprocation by the second party, others may verify the transaction and confirm the failure.
