Time-Varying Binary-Ternary Encoding for Optical Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing devices in edge deployments are vulnerable to malicious attacks due to limited physical protections and fewer security mechanisms, making them susceptible to interception and compromise of optical communications.
Innovation Solution
Implementing a security framework that dynamically switches between binary and ternary encoding schemes for optical data transmissions, ensuring that different types of information are encoded differently to prevent malicious entities from interpreting the communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single encoding scheme is used for optical communications, then the system is simple and easy to implement, but the security against malicious interception is weak
Solution Approach 1:
The patent applies dynamics by making the encoding scheme changeable over time. The system dynamically switches between binary and ternary encoding schemes based on challenge-response authentication, ensuring that the encoding method is not fixed and adapts to different communication contexts, thereby preventing malicious entities from predicting or intercepting communications effectively
Solution Approach 2:
The patent changes the parameter of encoding scheme (from binary to ternary and vice versa) based on authentication results. This parameter change ensures that different types of information are encoded differently, making it difficult for malicious entities to interpret communications even if they intercept them, while resolving the contradiction between security improvement and complexity management
2Reliability
If multiple encoding schemes are used to enhance security, then the likelihood of data compromise is reduced, but the complexity of the communication system increases
Solution Approach 1:
The patent segments the communication process into distinct phases: challenge transmission, response encoding, authentication, and secure communication establishment. Different encoding schemes are applied to different segments (binary for challenges, ternary for authenticated responses), which manages complexity by organizing the system into manageable parts while enhancing security through varied encoding
Solution Approach 2:
The patent uses an intermediary authentication mechanism (challenge-response protocol) that mediates between the sender and receiver. This intermediary process verifies identities before establishing secure communication, ensuring that only authenticated devices can use the ternary encoding scheme for critical data transmission, thereby balancing security enhancement with complexity management

AI summary
Methods and systems for managing operation of endpoint devices are disclosed. The operation of the endpoint devices may be managed by requiring that the endpoint devices obtain security data from other devices. If the security data is not obtained, the endpoint devices may seal at least some of their functions from use by users. By limiting the functions of the endpoint devices, malicious parties may be less likely to be able to compromise the endpoint devices. The endpoint devices and other devices may be operably connected via a channel that limits that distance between the endpoint devices and the other devices. If the distance is exceeded, then the endpoint devices may be deprived of access to the security data.
