Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual rotation of cryptographic materials is performed, then security is maintained, but productivity decreases and downtime increases due to the increasing number of computer systems
Solution Approach 1:
The system enables self-service by allowing machines to automatically rotate their own cryptographic materials without requiring manual intervention from IT support staff. The automated rotation mechanism monitors expiration dates and performs rotation operations autonomously, eliminating the bottleneck of manual processing while maintaining security standards.
Solution Approach 2:
The system performs preliminary action by proactively monitoring cryptographic material expiration dates and initiating rotation before the materials actually expire. This advance preparation ensures continuous security without downtime, as the rotation occurs in advance rather than reactively when expiration is approaching.

The automated rotation mechanism monitors expiration dates and performs rotation operations autonomously, eliminating the bottleneck of manual processing while maintaining security standards.
Solution Approach 2:
The system implements a universal automated rotation mechanism that handles multiple computer systems and cryptographic relationships through a single unified approach. The centralized management platform can monitor and coordinate rotation across diverse systems without requiring system-specific manual procedures, thereby reducing overall management complexity as the system scales.

AI summary
Automatic rotation of materials such as cryptographic materials prevents downtime in computer systems through a method in which the business logic of a DLN, such as a smart contract, receives a request from a given machine to access a resource such as a stream of chained identifiers. The logic checks the stream for a status marker that says the materials need rotation. If so, the business logic replies that rotation is required. When the marker is not there, the logic retrieves the expiry information on the cryptographic material and calculates how long until expiration. If the remaining validity is not enough, the business logic forces a rotation of the cryptographic material by storing the status marker in the stream and notifying the machine. The machine responds by working with the business logic to do the rotation.
