Remote Command Authentication via Dynamic PIN Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems lack flexibility and security in remote control of electronic devices, as they require pre-agreed protocols for commands and are vulnerable to unauthorized access once security codes are broken, limiting post-release product updates and expansions.
Innovation Solution
A system that generates a unique identifier to produce a Personal Identification Number (PIN) code for authenticating remote sources, allowing embedded commands to be processed only if the source is verified, enabling secure and flexible control of electronic devices for updates and operations without prior protocol agreement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-agreed communication protocols are used for remote control, then command execution is standardized and reliable, but system flexibility and adaptability are reduced
Solution Approach 1:
The patent implements dynamic protocol selection where the communication protocol is not fixed beforehand but can be adaptively chosen based on the specific command type and device state. The system maintains a library of multiple protocols and selects the appropriate one during runtime, allowing both standardized execution for common commands and flexibility for emerging command types.
Solution Approach 2:
The system allows protocol parameters to be dynamically adjusted based on command requirements. Instead of using a single rigid protocol, the system can modify protocol parameters such as authentication methods, data formats, and transmission modes to suit different command scenarios, thereby maintaining reliability while enhancing adaptability.
2Reliability
If security codes are used to prevent unauthorized commands, then device security is improved, but once broken the device becomes vulnerable to unauthorized control
Solution Approach 1:
The system performs preliminary authentication actions before command execution by verifying digital signatures and cryptographic credentials. This preliminary security check ensures that only authorized commands are processed, and the authentication mechanism is designed to be computationally infeasible to break, providing proactive security rather than reactive response to breaches.
Solution Approach 2:
The patent introduces cryptographic intermediaries such as digital signatures and certificate authorities that mediate between the command source and the executing device. These intermediaries provide verifiable proof of authorization without exposing secret keys, creating a security layer that is resistant to traditional code-breaking attacks and enables secure remote authentication.
3Reliability
If protocol requirements must be met before command execution, then command security is maintained, but command execution speed and productivity are reduced
Solution Approach 1:
Security authentication and protocol verification are performed in advance during device initialization and connection establishment. By completing these security checks beforehand, the system eliminates the need for repeated verification during each command execution, thereby maintaining strong security protocols while significantly improving command execution speed and overall system productivity.

AI summary
A method for secured execution of commands is described. Initially, a second electronic device authenticates a first electronic device and registers the first electronic device as a trusted device. Thereafter, up receipt of a message with one or more embedded commands, such commands are executed without any pre-established communication protocol if the message is from the registered first electronic device.
