Secure Communications Agent for Granular Application Delegation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in securely communicating sensitive information over the Internet due to the complexity of cryptographic infrastructure and the risk of trust exploitation by third-party organizations providing cryptographic functionality, as well as the potential security risks of allowing third-party applications access to cryptographic keys.
Innovation Solution
A secure communications infrastructure that allows users to delegate permissions to third-party applications at a granular level, with an agent component acting as an intermediary between third-party applications and the core infrastructure, preventing access to security-specific data and maintaining system security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If third-party applications are allowed direct access to cryptographic keys to perform operations on behalf of users, then application functionality and automation are improved, but security risk increases due to potential key exposure
Solution Approach 1:
The patent introduces an agent component as an intermediary layer between third-party applications and the cryptographic infrastructure. The agent receives requests from applications, validates them against delegation policies, and performs cryptographic operations using keys that never leave the secure infrastructure. This mediator architecture enables application automation while maintaining security by ensuring applications never directly access cryptographic keys.
2Ease of operation
If cryptographic infrastructure is made transparent and easy to use, then ease of operation is improved, but trust requirements increase as users must trust the infrastructure providers
Solution Approach 1:
The patent extracts the trust requirement from the cryptographic infrastructure providers and relocates it to the user's own agent component. By making the agent a user-controlled element rather than a provider-controlled service, the system maintains transparency and ease of use while eliminating the need to trust third-party infrastructure providers with cryptographic operations.
3Reliability
If granular delegation permissions are implemented to control application access, then security is improved, but system complexity increases due to permission management overhead
Solution Approach 1:
The patent implements preliminary action by requiring users to configure granular delegation permissions in advance, before any application requests access. The agent stores these pre-defined policies and automatically evaluates them when applications make requests. This approach provides fine-grained security control while simplifying runtime operations, as the complexity of permission management is resolved beforehand rather than during each cryptographic operation.

AI summary
An organization that wishes its messages to be secure (the “communicating organization”) uses services of a secure communications infrastructure to securely exchange communications among its users. The secure communications infrastructure allows granting to third-party applications the permission to act on behalf of the users when using the secure communications infrastructure. This delegation may be accomplished at a very granular level, specifying the particular applications that are authorized to act on behalf of a user, the particular operations that those applications are authorized to perform, and/or in which contexts the applications may perform the operations. An agent component acts as an intermediary between third-party applications and the core of the secure communications infrastructure. This permits the third-party application to take actions on behalf of the user, while also preventing the third-party applications from obtaining the security-specific data that could lead to a breach of security.
