Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical signals are transmitted on wires or terminals for data processing, then data transmission and processing functionality is achieved, but the signals provide detectable indications of circuit activity that can be monitored by attackers
Solution Approach 1:
The patent introduces a cloaking circuit as an intermediary component between the processing circuit and external wires/terminals. This cloaking circuit modifies the electrical signals to hide circuit activity indications while allowing legitimate data transmission to continue uninterrupted.
Solution Approach 2:
The patent changes the parameters of electrical signals by adding noise or modifying signal characteristics through the cloaking circuit. This alters the signal properties to obscure circuit activity patterns from potential attackers while maintaining functional data transmission.
2Ease of operation
If standard electrical terminals are used for signal transmission, then ease of connection and data transfer is achieved, but the terminals are vulnerable to monitoring attacks through electrical connections and field sensing
Solution Approach 1:
The cloaking circuit serves as a protective intermediary that interfaces between standard electrical terminals and the external environment. It maintains ease of connection while blocking harmful monitoring attacks by obscuring signal activity indications.
Solution Approach 2:
The patent converts the inherently detectable nature of electrical signals into a benefit by using the cloaking circuit to deliberately add obfuscation. The same electrical transmission medium that enables data transfer also carries the cloaked signals that protect against attacks.
3Productivity
If processing circuits operate with visible signal activity patterns, then normal circuit functionality and performance are achieved, but activity patterns reveal information about circuit state that can be exploited by attackers
Solution Approach 1:
The cloaking circuit acts as an information-filtering intermediary that allows productive circuit operation to continue while blocking the leakage of sensitive information about circuit state and activity patterns to external attackers.
Solution Approach 2:
The patent modifies signal parameters through the cloaking circuit to hide information about circuit activity patterns. This maintains normal circuit performance while preventing attackers from inferring sensitive information from observable signal characteristics.

AI summary
The indications of circuit activity in an electrical signal may be obtained by monitoring the electrical terminal or wire by way of an electrical connection or by sensing changes in magnetic and electric fields. A cloaking circuit may be coupled to the electrical terminal to obfuscate the indications of circuit activity of the processing circuit to reduce or avoid successful monitoring that may lead to a breach of data security. Obfuscating the indications of circuit activity includes modifying a signal on the electrical terminal to render the circuit activity more obscure, unclear, or unintelligible. In some examples, modifying the signal on the electrical terminal may include generating a cloaking signal on the electrical terminal. In some examples, generating the cloaking signal may include analyzing the signal to detect indications of circuit activity and generating the cloaking signal based on the circuit activity.
