Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current software-based cybersecurity solutions are inadequate in managing security risks, as they are vulnerable to human errors, misconfigurations, and attacks, leading to significant economic losses and data breaches, particularly in critical infrastructure.
Innovation Solution
Implementing hardware security barriers that use immutable hardware to generate and distribute cryptographically secure keys, ensuring secure communication by intercepting and validating packets, and preventing unauthorized access, thereby creating a physical barrier between the processor and the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If software-based cybersecurity solutions are used, then ease of operation and adaptability are improved, but reliability and security strength deteriorate due to vulnerability to human errors, misconfigurations, and attacks
Solution Approach 1:
The patent replaces software-based cybersecurity mechanisms with hardware-based security barriers. The hardware security barrier uses dedicated hardware circuits to generate, store, and manage cryptographic keys, eliminating the vulnerabilities of software-based systems. This substitution maintains operational functionality while dramatically improving reliability by removing software-related weaknesses such as human errors and misconfigurations.
Solution Approach 2:
The hardware security barrier acts as an intermediary component between the processor and the network. It intercepts all network traffic and performs security functions (key generation, encryption, decryption, authentication) before data reaches the processor or network. This intermediary position allows the system to maintain ease of operation through automated security functions while achieving superior reliability through hardware-enforced security.
2Reliability
If hardware security barriers are implemented, then reliability and security strength are improved, but device complexity increases
Solution Approach 1:
The security system is segmented into distinct functional components: the hardware security barrier for security functions, the processor for computation, and the network interface for communication. The hardware security barrier itself is divided into functional modules including key generation units, encryption/decryption units, and authentication modules. This segmentation allows the complex security functions to be distributed across dedicated hardware components, improving reliability while managing complexity through modular architecture.
3Reliability
If immutable hardware is used for security functions, then reliability is improved, but adaptability and versatility deteriorate
Solution Approach 1:
The hardware security barrier incorporates dynamic elements that allow it to adapt to different security scenarios while maintaining immutable core functionality. The system can dynamically generate new cryptographic keys, update encryption algorithms, and adjust security parameters based on threat levels and operational requirements. This dynamic capability enables the immutable hardware to serve multiple purposes across different networks and applications, resolving the contradiction between immutability and adaptability.

AI summary
One embodiment includes hardware-based cybersecurity devices that create a physical barrier (“hardware security barrier”) between a computer's (or other device's) processor and a public or private network. Hardware security barriers typically use immutable hardware in accomplishing cybersecurity activities including generating and distributing cryptographically secure numbers, encryption, decryption, source authentication, and packet integrity verification. This hardware security barrier protects against remote threats and guarantees that all exported and received data are strongly encrypted. A hardware security barrier can be included in any computing or networking device that contains a network interface. One embodiment of a hardware security barrier is implemented as part of a network interface, such as, but not limited to being part of a network interface controller, or as a standalone unit between a communications interface of a host system and a connection to a network.
