Unified Encryption Engine for Continuous Data Stream Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems face inefficiencies when processing and managing both encrypted and non-encrypted data on storage media, requiring interruptions in the data stream to process different types of data, which impacts read and write times.
Innovation Solution
A method where user data is encrypted with a well-known key, allowing both encrypted and non-encrypted data to be processed in a single encryption path, using a 'zero key' for user data and application-specific keys for application data, enabling seamless reading and writing without interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If both encrypted and non-encrypted data are written on the storage medium in separate forms, then data security is maintained, but reading and writing operations require interruptions in the data stream to process different types of data, reducing efficiency
Solution Approach 1:
The patent merges the processing paths for encrypted and non-encrypted data into a single unified encryption engine. By treating all data as encrypted and using a well-known key (such as a zero key) for user data, the system eliminates the need for separate processing paths and interruptions, while maintaining security through contextual key selection
Solution Approach 2:
The patent changes the encryption parameter (key) dynamically based on data context rather than changing the processing mode. User data is encrypted with a well-known key while application data uses application-specific keys, allowing the same encryption engine to handle both types continuously without interruptions
2Ease of operation
If the encryption engine is restarted frequently to handle non-encrypted data segments, then data accessibility is maintained, but the overall time to read and write data increases
Solution Approach 1:
The patent enables continuous encryption engine operation by eliminating restarts. The encryption engine processes all data segments continuously using the appropriate key for each segment based on contextual identification, maintaining data accessibility while preventing time loss from frequent engine restarts
3Reliability
If separate processing paths are used for encrypted and non-encrypted data, then proper security management is achieved, but device complexity increases
Solution Approach 1:
The patent makes the encryption engine universal by enabling it to handle both user data and application data through a single interface. The engine automatically selects the appropriate key based on data context, eliminating the need for multiple specialized processing paths while maintaining proper security management
Data Source
AI summary
A method, system and program are disclosed for efficiently processing host data which comprises encrypted and non-encrypted data and is to be written to a storage medium. The encrypted data is written to the storage medium in encrypted form. The non-encrypted data is encrypted by a storage device using a well known encryption key and written to the storage medium. In this way, the data that is processed by the storage device to and from the storage medium can always be processed through a single encryption engine.
