XML Security Gateway Offloading Server Cryptography
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional XML processing technologies are verbose and resource-intensive, leading to bottlenecks in information flow between enterprise applications, and are insecure as they rely on server-based implementations that are difficult to manage and upgrade, with XML payloads often evading network security systems.
Innovation Solution
A markup language processing device that operates within a networking environment to parse and process XML data streams, performing encryption, decryption, and digital signing using hardware acceleration, and provides a centralized security gateway to enforce organizational policies across XML-enabled applications, offloading server tasks and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If server-based XML processing is used, then processing capability is provided, but system complexity and difficulty of management increase
Solution Approach 1:
The patent introduces a network device as an intermediary component that performs XML processing functions (parsing, validation, transformation) centrally at the network level. This mediator handles XML message processing between clients and servers, reducing the complexity burden on individual servers and centralizing management capabilities in the network device.
Solution Approach 2:
The patent segments XML processing functions into distinct modular components including XML parser, schema validator, and transformation engine that can be independently configured and managed in the network device. This segmentation allows for easier maintenance and updates of specific processing functions without affecting the entire system.
2Productivity
If conventional XML processing is used, then information exchange is enabled, but processing performance creates bottlenecks
Solution Approach 1:
The patent implements preliminary XML processing actions at the network device level, including parsing and validation, before messages reach the application servers. This preliminary processing reduces the time burden on servers and enables faster information flow by pre-filtering and pre-processing XML messages in the network path.
3Reliability
If server-based security implementation is used, then security functions are provided, but security vulnerabilities increase
Solution Approach 1:
The patent positions the network device as a security intermediary that performs XML message security processing including encryption, decryption, and digital signature verification. This centralized security enforcement at the network level reduces security vulnerabilities by providing consistent security policies and reducing the attack surface on application servers.
Data Source
AI summary
A markup language processing device processes markup language messages by receiving a message containing portions of tagged data formatted in a markup language and applying a transform selection rule set to at least one tagged rule selection data portion in the message to select at least one markup language transformation to apply to the tagged pre-transform data portion within the message. The markup language processing device applies the selected markup language transformation to transform the tagged pre-transform data portion to a tagged post-transform data portion according to a transformation function and then conditionally forwards the message. The markup language processing device operates on behalf of a computerized device that is not required to process the message due to operation of the at least one markup language transformation within the markup language processing device. The markup language processing device can process XML message for security and other purposes thus offloading such processing requirement from server computer systems.
