Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tokenization and encryption processes face challenges in efficiently managing and securing cryptographic blobs, which are integral to data security, particularly due to the need for computational complexity, compatibility with evolving algorithms, and potential security breaches.
Innovation Solution
A third-party server manages cryptographic material, generating a large quantity of cryptographic blobs in advance, which are selectively provided to client devices upon request, ensuring compatibility and security by periodically updating and refreshing the material.

Engineering Contradiction Analysis
1Reliability
If cryptographic blobs are generated on-demand using computationally complex algorithms, then security is improved, but computational delay increases
Solution Approach 1:
The system pre-generates cryptographic blobs using computationally complex algorithms before they are needed. These pre-generated blobs are stored in a database, allowing the system to quickly retrieve them when tokenization is required without performing complex computations in real-time, thus resolving the contradiction between security and computational delay
Solution Approach 2:
The system maintains a储备 (reserve) of pre-generated cryptographic blobs in the database that can be quickly deployed when security threats are detected or when computational resources are constrained. This cushioning approach ensures that security requirements are met without incurring computational delays during critical operations
2Reliability
If cryptographic material is frequently updated to maintain security, then security is improved, but system complexity increases
Solution Approach 1:
The system automatically manages cryptographic material updates through scheduled tasks and event-driven mechanisms. When security threats are detected or time-based rotation policies are triggered, the system self-updates cryptographic blobs in the database without requiring manual intervention, thus improving security while minimizing the operational complexity burden on users
Solution Approach 2:
The system implements monitoring mechanisms that detect security threats and automatically trigger cryptographic material updates. This feedback loop ensures that security is maintained through frequent updates while the automation reduces the perceived complexity for system operators
3Ease of operation
If cryptographic blobs are transmitted over the network, then availability is improved, but security risk increases
Solution Approach 1:
The system extracts cryptographic blobs from the central database and loads them into volatile memory of local devices only when needed for tokenization operations. This extraction approach maintains availability by making blobs accessible locally while reducing security risks by minimizing network transmission and exposure time
Solution Approach 2:
The system uses encrypted communication channels and secure transmission protocols as protective layers when cryptographic blobs must be transmitted over the network. This approach maintains availability while mitigating security risks through cryptographic protection during transmission

AI summary
Systems, methods, and apparatuses are described for crypto-material life-cycle management for tokenization and/or encryption. A computing device may generate cryptographic material comprising one or more blobs. Each of the blobs may be usable for encryption and/or tokenization for different field types and via various different encryption/tokenization algorithms. Multiple cryptographic blobs might be generated in advance for the same field type/algorithm, such that the cryptographic blobs are quickly available for use. In response to computing device requests for such cryptographic blobs, a cryptographic blob for a particular field/algorithm may be identified and transmitted. The cryptographic material may be refreshed periodically, when most and/or all of the cryptographic blobs are used up, or upon detection of a security breach. The cryptographic material may be appended based on new fields and/or algorithms such that the cryptographic material is backwards- and forwards-compatible.
