Hands-Free Access Management with Trusted Hardware Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computing systems are vulnerable to malware infections, which can compromise sensitive user information, leading to privacy and security risks.
Innovation Solution
A trusted hardware computing device is integrated with a legacy system to provide secure communication and protect sensitive information by performing authentication, encryption, and detecting malicious attacks, while preventing the legacy system from accessing this information directly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a legacy computing system is used, then ease of operation and compatibility are maintained, but security and data protection deteriorate due to malware vulnerabilities
Solution Approach 1:
A trusted hardware computing device is introduced as an intermediary between the legacy computing system and the network. This device performs authentication, encryption, and malware detection functions, allowing the legacy system to maintain its operational simplicity while gaining enhanced security through the intermediary's protective functions.
Solution Approach 2:
The computing system is segmented into a legacy environment and a separate trusted hardware computing device. This segmentation isolates security-critical functions (authentication, encryption, malware detection) from the vulnerable legacy system, allowing the legacy system to operate unchanged while the trusted device handles security concerns separately.
2Ease of operation
If sensitive information is stored in the legacy system, then ease of access is maintained, but data protection and privacy deteriorate due to malware infections
Solution Approach 1:
The trusted hardware computing device acts as an intermediary that intercepts and protects sensitive information before it reaches the network or is accessed by potentially malicious software. It performs authentication and encryption of data, ensuring that even if malware infects the legacy system, the sensitive information remains protected.
Solution Approach 2:
The trusted device performs preliminary security actions including authentication of users and encryption of data before any potential malware can access the information. It detects and prevents malicious attacks in advance, creating a protective barrier that stops harmful factors from reaching sensitive data stored in the legacy system.
3Productivity
If direct network access is provided to the legacy system, then productivity is maintained, but security and vulnerability to attacks increase
Solution Approach 1:
The trusted hardware computing device is positioned between the legacy system and the network, serving as a security intermediary. It maintains network connectivity for productivity while filtering out malicious attacks through authentication and detection functions, allowing legitimate traffic to pass through while blocking harmful factors.
Solution Approach 2:
The trusted device rapidly detects and blocks malicious attacks, rushing through security checks at high speed to prevent harmful factors from reaching the legacy system. This allows the system to maintain productive network operations while quickly neutralizing threats that attempt to penetrate the security barrier.
Data Source
AI summary
A trusted component is suggested to be added to off the shelf computing systems such as PCs or smartphone providing secure functions for access management and credential protection—safe authentication, maintaining session integrity and validation of content modification. An additional advantage of the solution that it detects malware/hacking attempts on first try allowing of taking action while oblivious to the malware/hacker to avoid retaliation.
