Remote PC Boot via Handheld Wireless Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing boot-up process for computers is lengthy and requires physical presence, making it inconvenient to initiate remotely, especially as systems become more complex and networked.
Innovation Solution
A method using a remote, wireless communication device to detect and decipher data packets, generate a password key, and recover the necessary password to initiate the boot-up process securely, involving a network interface, electronic memory, and processor to execute the necessary code for remote boot-up.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the computer is placed in a power down state to save energy, then energy consumption is reduced, but the computer cannot be accessed or operated
Solution Approach 1:
The system performs preliminary actions by pre-generating and storing cryptographic key pairs (public and private keys) and password hashes before the power down state. The public key and encrypted password are transmitted to a remote device in advance, enabling future remote authentication without requiring the computer to remain powered on or physically accessible
2Ease of operation
If remote boot-up capability is added to allow remote access, then ease of operation is improved, but security risks increase
Solution Approach 1:
A cryptographic intermediary mechanism is introduced using public-key cryptography. The public key acts as a secure intermediary that can be freely transmitted to remote devices, while the private key remains securely stored in the computer's ROM. This intermediary system enables remote authentication without exposing sensitive security credentials
Solution Approach 2:
The system creates and transmits a copy of the encrypted password and public key to the remote device, while the original security credentials (private key and password hash) remain securely stored in the computer. This copying approach allows remote authentication without compromising the security of the original system
3Reliability
If the boot-up process is made more complex to include security measures, then security is improved, but the boot-up time increases
Solution Approach 1:
The system performs security verification actions in advance by pre-storing password hashes and cryptographic keys. During the actual boot-up process, the pre-computed cryptographic comparisons enable rapid authentication without requiring time-consuming real-time computations or iterative security checks
