Secure Environment for Telecommunication Connection Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for accessing connection data in telecommunications lack security and efficiency, as they require decryption of all data for search purposes, allowing potential unauthorized access and performance limitations, with the telecommunication company holding encryption and decryption keys.
Innovation Solution
The method involves encrypting connection data by the telecommunication provider and transmitting it to a secure environment where it is decrypted and stored temporarily in volatile memory, with generated encryption and decryption keys remaining within the secure environment, ensuring only authorized access and efficient deletion in case of unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection data is encrypted and stored by the telecommunication company, then security is improved, but access time and efficiency deteriorate because all data must be decrypted for search purposes
Solution Approach 1:
The system separates encrypted connection data from decryption keys by storing them in different locations (telecommunication company vs. secure environment). This segmentation allows the data to remain encrypted during storage while enabling efficient access when keys are available in the secure environment, resolving the contradiction between security and access efficiency.
Solution Approach 2:
A secure environment acts as an intermediary between the telecommunication company and authorized instances. This intermediary holds both the encrypted data and decryption keys, providing a controlled access point that maintains security while enabling efficient retrieval without requiring the telecommunication company to decrypt all data.
2Ease of operation
If the telecommunication company holds encryption and decryption keys, then access control is simplified, but security deteriorates because the company can decrypt data without legitimate cause
Solution Approach 1:
The decryption keys are extracted from the telecommunication company and transferred to a separate secure environment. This extraction removes the ability of the telecommunication company to unilaterally decrypt data, enhancing security while maintaining access control through the secure environment's authorized access mechanisms.
Solution Approach 2:
The secure environment serves as an intermediary that controls access to decryption keys. Instead of the telecommunication company directly holding keys, the intermediary secure environment manages key distribution and decryption operations, preventing unauthorized access while maintaining operational efficiency.
3Adaptability or versatility
If all encrypted connection data is decrypted for each authorized access, then data search capability is improved, but performance deteriorates due to the time-consuming decryption process
Solution Approach 1:
The system performs preliminary actions by pre-positioning decryption keys in the secure environment and maintaining encrypted data in a ready-state. When access is required, the pre-positioned keys enable immediate decryption of only the necessary data portions, rather than requiring comprehensive decryption of all stored data, thus improving performance while maintaining search capability.
4Duration of action of stationary object
If connection data is stored in permanent storage, then data retention is improved, but security deteriorates because decrypted data cannot be quickly deleted in case of unauthorized access
Solution Approach 1:
The system implements dynamic storage by keeping decrypted connection data in volatile memory rather than permanent storage. This dynamic approach allows the data to be automatically cleared when power is lost or when unauthorized access is detected, providing both data retention during legitimate use and rapid elimination when security threats arise.
Solution Approach 2:
The system uses volatile memory for storing decrypted connection data, which acts as a short-living storage medium. This disposable storage approach ensures that data can be quickly eliminated by simply clearing the volatile memory, providing enhanced security while maintaining data availability during the authorized access period.
