Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional weapons lack adequate security measures to prevent message spoofing and unauthorized access, allowing nefarious users to manipulate weapon functionality through transparent and unencrypted messages.
Innovation Solution
Encoding messages with spreading codes and employing direct sequence spread spectrum operations to secure communication between electronic components within weapons, using dynamic message encoding to enhance security against spoofing and unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If messages are transmitted transparently and unencrypted between electronic components, then communication simplicity is maintained, but weapon security deteriorates allowing message spoofing and unauthorized access
Solution Approach 1:
The patent applies preliminary action by encoding messages with spreading codes before transmission between electronic components. The encoding is performed in advance using direct sequence spread spectrum techniques, so that when the message is transmitted, it is already secured against spoofing and unauthorized access. This resolves the contradiction by implementing security measures beforehand rather than adding complex verification mechanisms during communication.
2Reliability
If spreading codes are used to encode messages, then message security is improved, but communication processing complexity increases
Solution Approach 1:
The patent implements universality by integrating the spreading code encoding and decoding functions directly into the electronic components that already handle message transmission. The same electronic components that transmit and receive messages also perform the encoding and decoding operations using stored spreading codes. This multi-functionality approach resolves the contradiction by consolidating security processing within existing communication hardware, avoiding the need for separate complex processing systems.
3Object-affected harmful factors
If dynamic message encoding is implemented, then protection against spoofing is enhanced, but computational requirements increase
Solution Approach 1:
The patent applies the principle of using simple, readily available spreading codes that can be generated and discarded efficiently. The electronic components use pseudorandom spreading codes that are computationally inexpensive to generate and apply. Each message or message group can use a different spreading code or code phase, providing dynamic encoding without requiring complex computational resources. This resolves the contradiction by using lightweight encoding techniques that provide spoofing resistance without excessive energy consumption.

AI summary
The present disclosure provides systems and techniques for communicating across electronic components of a device. The device may be a gun, and the device may encode messages to improve the security of the device. The device may obtain a first spreading code, encode, at a first electronic component, a first message according to the first spreading code to produce a first encoded message, transmit the first encoded message from the first electronic component to a second electronic component across a physical communication channel, decode, at the second electronic component, the first encoded message according to the first spreading code, and perform a first action in response to the decoding the first encoded message. The first action may include discharging electric charge from a capacitor bank, charging the capacitor bank, firing a projectile, arming the device, disarming the device, or transmitting data across an additional communication channel.
