Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cryptography communication systems fail to notify users about the depletion of finite encryption keys, making it difficult to prioritize communication based on available encryption key amounts.
Innovation Solution
A cryptography communication system with a key exchange node that includes a key accumulation amount monitoring function, notification, and display units, allowing users to predict and manage encryption key depletion by monitoring and displaying the accumulation amount, and controlling communication bandwidth accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a one-time pad method or quantum key distribution is used to ensure secure encryption, then encryption security is improved, but the encryption key will be depleted when consumption amount exceeds supply amount
Solution Approach 1:
The system implements a feedback mechanism where the key exchange node notifies the application execution environment of the encryption key accumulation amount. This allows the system to monitor key consumption levels and provide information back to users about key depletion status, enabling informed decisions about communication priority without compromising security
Solution Approach 2:
The key exchange node acts as an intermediary between the encryption/decryption execution environment and the application execution environment. It manages the encryption key accumulation and distribution, providing a controlled interface that tracks and reports key availability to applications without exposing the actual key management complexity
2Loss of information
If the encryption key accumulation amount is monitored and notified to users, then user awareness of key depletion is improved, but system complexity increases
Solution Approach 1:
The key exchange node performs multiple functions: it generates encryption keys, shares keys with communication counterparts, accumulates keys, and notifies applications of key accumulation amounts. By consolidating these functions into a single node, the system avoids distributing complexity across multiple components while maintaining comprehensive key management and user awareness

AI summary
Providing a cryptography communication system capable of notifying a user of an accumulation amount of an encryption key. According to one embodiment, a cryptography communication system includes an application execution environment, an encryption/decryption execution environment, and a key exchange node. The encryption/decryption execution environment encrypts transmission data of the application program and decrypts encrypted reception data of the application program while consuming an encryption key for each predetermined processing unit. The key exchange node generates the encryption key, shares the generated encryption key with a communication counterpart, and accumulates an encryption key shared with the communication counterpart. The key exchange node includes a key accumulation amount monitoring function unit. The key accumulation amount monitoring function monitors an accumulation amount of the encryption key. The application execution environment includes a key accumulation amount notification function unit. The key accumulation amount notification function unit notifies a user of the application program or the application program of an accumulation amount of the encryption key acquired by the key accumulation amount monitoring function unit.
