Variable-Length Data Encoding for Hack-Resistant Network Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data communication systems are vulnerable to hacking as they rely on user authentication and encryption methods that can be bypassed through local computer vulnerabilities, necessitating more robust security measures.
Innovation Solution
A method involving variable-length encoding and decoding of data streams, where data is encrypted and decrypted at a central device before transmission over external networks, using random value insertion and variable word lengths to enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional encryption algorithms are used to encrypt data locally at computers/servers, then data security is improved, but hackers can still bypass security through backdoors of local computers/servers
Solution Approach 1:
The patent introduces a trusted third-party device (security appliance) as an intermediary between data sources and destinations. This intermediary performs encryption and decryption operations, preventing direct access to encryption keys at local computers/servers. The intermediary device acts as a mediator that secures data transmission by centralizing cryptographic operations in a dedicated security infrastructure, thereby eliminating local backdoor vulnerabilities.
2Reliability
If data is encrypted at local computers/servers before transmission, then data security is improved, but the encryption and decryption processes become complex and resource-intensive
Solution Approach 1:
The patent merges multiple cryptographic functions (encryption, decryption, key management) into a single integrated trusted intermediary device. Instead of distributing complex cryptographic operations across multiple local systems, the invention consolidates these functions in one centralized security appliance, simplifying the overall system architecture while maintaining security.
Solution Approach 2:
The trusted intermediary device is designed to perform multiple cryptographic functions universally - it can encrypt data from any source, decrypt data for any destination, and manage multiple encryption keys. This multi-functional design eliminates the need for separate encryption systems at each local computer, reducing overall system complexity.
3Adaptability or versatility
If data is transmitted over external networks like the Internet, then communication flexibility is improved, but data security deteriorates due to exposure to hackers and network vulnerabilities
Solution Approach 1:
The patent applies preliminary encryption actions at the trusted intermediary device before data enters the public network. By pre-encrypting data with strong cryptographic algorithms and managing keys securely at the intermediary, the system prepares data for secure transmission before it exposes to network vulnerabilities. This preliminary security measure protects data throughout its journey across flexible external networks.

AI summary
A method for variable length decoding, the method including: receiving, in a default word length mode, at least one first data word having a default first word length; combining the received at least one first data word as a first portion of data; receiving, after the at least one first data word, a transition word indicative of transitioning to a variable word length mode; receiving, after the transition word, a first word length word indicative of a second word length; receiving, after the first word length word, at least one second data word having the second word length; and combining the received at least one second data word as a second portion of the data.
