Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secure communication systems face challenges in adopting Public Key Infrastructure (PKI) due to cumbersome usage, particularly in person-to-person and person-to-group communications, where encryption keys are often managed by service providers, leaving user data vulnerable in case of provider breaches.
Innovation Solution
The system introduces a method for automatically disseminating private keys, allowing users to securely transfer their private keys to other devices without breaking the cryptography, and enabling users to manage their own encryption keys, ensuring security and integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If service providers manage encryption keys for users, then key management becomes simplified and automated, but user data becomes vulnerable to compromise in case of provider breaches
Solution Approach 1:
The system segments key management into two distinct components: (1) a service provider-managed component that handles key distribution, storage coordination, and automated provisioning, and (2) a user-controlled component that maintains cryptographic security through user-held secrets and device-specific key pairs. This segmentation allows the service provider to simplify operations without compromising security, as the provider never possesses the actual decryption keys.
Solution Approach 2:
The patent introduces an intermediary key management architecture where the service provider acts as a mediator that facilitates key distribution and management operations without having access to the actual cryptographic secrets. The intermediary coordinates between users and their devices, enabling automated key provisioning and management while maintaining the security boundary that prevents provider access to encrypted data.
2Reliability
If users manage their own encryption keys, then data security is improved, but key management becomes cumbersome and complex
Solution Approach 1:
The system enables users to perform self-service key management operations through automated processes. Users can provision keys, register devices, and manage their cryptographic materials through automated interactions with the service provider's infrastructure, eliminating the need for manual key distribution and reducing operational complexity while maintaining user control over security.
Solution Approach 2:
The patent implements preliminary automated key provisioning and device registration processes that prepare the cryptographic infrastructure in advance. Keys are pre-generated and distributed to authorized devices before actual communication needs arise, and device authorization is pre-configured through automated registration processes, reducing the complexity of on-demand key management operations.
3Reliability
If private keys are manually distributed to devices, then security control is maintained, but the process becomes time-consuming and inefficient
Solution Approach 1:
The patent replaces manual mechanical key distribution processes with automated electronic key provisioning systems. Instead of physical key exchange or manual configuration, the system uses automated digital key generation, encryption, and distribution through secure communication channels, dramatically increasing distribution speed while maintaining security through cryptographic protection of the automated processes.
Solution Approach 2:
The system changes the parameters of key distribution from manual, sequential operations to automated, parallel processes. Multiple keys can be distributed simultaneously to multiple devices through automated scripts and systems, changing the operational mode from time-consuming manual procedures to efficient automated batch processing while maintaining security through consistent application of cryptographic protocols.
4Device complexity
If encryption keys are stored on service provider servers, then key management is centralized and simplified, but the system becomes vulnerable to unauthorized access and malfeasance
Solution Approach 1:
The patent extracts the critical security element (the actual decryption keys) from the service provider's infrastructure and places it under user control. The service provider's system stores only encrypted data and metadata, while the decryption keys are held by users on their own devices. This extraction eliminates the single point of vulnerability at the provider's servers while maintaining centralized management capabilities for non-sensitive operations.
Solution Approach 2:
The system transitions from a single-dimensional centralized key storage model to a multi-dimensional distributed architecture. Keys are distributed across multiple dimensions: user-controlled storage, device-specific storage, and service provider coordination. This dimensional distribution reduces vulnerability to centralized breaches while maintaining management efficiency through coordinated access control across the distributed system.
Data Source
AI summary
Secure communications can be established in which a request is received from a client computing device to instantiate a virtual key store (VKS) node. In response to the request, a cryptographically calculated uniform resource locator (URL) is generated. In addition, a crytopgraphic identity certificate is received from a certification authority server. Subsequently, a virtual desktop infrastructure (VDI) instance is instantiated and configured with the cryptographic identity certificate. Communications are then established between the client computing device and the VDI instance using the generated cryptographically calculated URL such that the VDI instance acts as a cryptographic proxy with at least one remote computing device.
