Encrypted Context Authentication for Secure Data Partition Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing dynamic changes in server system databases and data partitions is challenging due to inefficiencies in data object management, security vulnerabilities, and risks of data exfiltration and confused deputy attacks in multi-tenant architectures.
Innovation Solution
Implementing data access authentication based on encrypted context for data partitions, which includes metadata and tenant identifiers, to enhance security and compartmentalization, mitigating risks such as data exfiltration and confused deputy attacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional data access methods are used in multi-tenant architectures, then ease of operation is maintained, but security vulnerabilities and risks of data exfiltration increase
Solution Approach 1:
The patent segments data access authentication by implementing partition-specific authentication mechanisms. Each partition has its own authentication context that is validated independently, allowing security to be enforced at the partition level rather than requiring system-wide complex authentication protocols.
Solution Approach 2:
The patent introduces an authentication context as an intermediary element between the data access request and the partitioned data. This context contains partition identifiers and validation information that mediates the authentication process, simplifying the overall security architecture while maintaining strong security controls.
2Reliability
If data partitions are implemented for multi-tenant isolation, then data security is improved, but management and support complexity increases
Solution Approach 1:
The patent implements a universal authentication context structure that can be applied across all partitions and tenants. This single authentication mechanism handles multiple functions including partition identification, tenant validation, and access control, reducing management complexity despite the presence of multiple partitions.
Solution Approach 2:
The authentication context provides feedback mechanisms that automatically validate partition identifiers and authentication information. This automated validation reduces manual management overhead by providing real-time verification of partition access rights without requiring complex manual configuration.
3Reliability
If encrypted context authentication is implemented, then unauthorized access is reduced, but processing overhead increases
Solution Approach 1:
The patent performs preliminary validation of the authentication context by checking the partition identifier and authentication information before accessing the actual partitioned data. This preliminary check ensures security requirements are met early in the processing pipeline, preventing unauthorized access while minimizing overhead for legitimate requests.
Data Source
AI summary
Methods, apparatuses, or computer program products that provide data access authentication for a data partition based on encrypted context associated with a data access request for the data partition. In some examples, a data access request to access data within a partition is received. In some examples, the data access request is associated with an encrypted context for a requesting entity identifier associated with the data access request. In some examples, a partition identifier and an encrypted partition key for the partition are identified based on the data access request. Additionally, a candidate validation partition key for the partition is generated based on the encrypted partition key, the encrypted context, and the partition identifier. In some examples, the candidate validation partition key is validated based on a comparison between the candidate validation partition key and a validation partition key associated with the partition to facilitate processing the data access request.
