Transparent Web Content Verification Tree for Dynamic JavaScript Trust
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern web applications face challenges in efficiently validating the security and authenticity of web content due to the dynamic loading of third-party JavaScript modules, which traditional methods like content security policies (CSPs) struggle to manage effectively, especially with frameworks like Angular, and existing hashing methods are inefficient for large-scale applications.
Innovation Solution
A Transparent Web Content Verification Tree (TWCVT) framework using modified Verkle Trees and Pedersen commitments for efficient validation, incorporating elliptic curve cryptography to ensure authenticity, integrity, and trust verification of web content, with searchable and auditable logs for security attestations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content security policies (CSPs) are used to control dynamic JavaScript modules, then security validation capability is improved, but ease of operation deteriorates due to complexity and incompatibility with modern frameworks
Solution Approach 1:
The patent introduces a web application provider as an intermediary that receives security attestations from third-party module providers. This mediator validates the integrity and security of JavaScript modules before they are executed, resolving the contradiction by providing automated security validation without requiring complex CSP configurations from the web application provider.
Solution Approach 2:
The patent replaces the mechanical CSP configuration system with a cryptographic attestation system using hashes and digital signatures. Instead of manually configuring CSP rules that are difficult to manage, the system automatically validates module integrity through cryptographic proofs provided by third-party providers, eliminating the operational complexity.
2Reliability
If hashing methods are used to identify trusted JavaScript modules, then security validation capability is improved, but productivity deteriorates due to inefficient validation for large-scale applications
Solution Approach 1:
The patent segments the validation process into two parts: third-party module providers generate and sign security attestations for their modules, while the web application provider only needs to verify these pre-computed attestations. This segmentation allows efficient validation without requiring the web application provider to perform complex hashing operations on all modules.
Solution Approach 2:
The patent implements preliminary action by having third-party module providers pre-generate and sign security attestations before the modules are loaded. The web application provider only needs to verify these pre-computed attestations, which significantly improves validation efficiency compared to performing comprehensive hashing and verification at runtime.
3Difficulty of detecting and measuring
If standard SCA tools are used to identify vulnerable components, then vulnerability detection capability is improved, but effectiveness deteriorates because components are uploaded dynamically
Solution Approach 1:
The patent implements a feedback mechanism where third-party module providers provide security attestations that include vulnerability information. The web application provider receives and verifies these attestations, which contain real-time information about the security state of dynamically loaded modules, enabling effective vulnerability detection without relying on static SCA tools.
Data Source
AI summary
The management of web page content includes maintaining an auditable log of trust verification relating to the web page content. The management further includes an attestation of a source of the web page content. The attestation relates to a security practice of the source, computer code provided by the source, a reputation of the source, and a history of the source. A modified version of a Verkle Tree is then applied to the auditable log and the attestation of the source.
