Restricted Data Channel Encoding for Secure Legacy Protocol Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In complex data processing systems with multiple entities, upgrading all components to support new protocol versions is impractical, leading to issues like inadequate security in older protocol versions, particularly in restricted data channels, which hinder secure transmission and authentication of sensitive data.
Innovation Solution
A method involving cryptographic records and time information is used to repurpose data fields, allowing secure transmission of significant information through restricted channels by combining elements with time information, enabling reconstruction and validation of full information at the recipient.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If older protocol versions are used to maintain compatibility with legacy systems, then system compatibility and ease of operation are improved, but security and data transmission capabilities deteriorate
Solution Approach 1:
The patent introduces an intermediary encoding mechanism that translates secure data into a format compatible with legacy protocols. The data field serves as a mediator that carries encrypted or encoded sensitive information through older protocol channels without requiring upgrades to the underlying communication infrastructure, thus maintaining compatibility while enhancing security
Solution Approach 2:
The patent changes the parameters of data representation by encoding sensitive information in non-obvious ways within existing data fields. By altering how data is structured and represented rather than how it is transmitted, the system achieves improved security through older protocols without requiring protocol upgrades
2Loss of information
If data fields are repurposed to carry additional information, then information transmission capability is improved, but data field structure and protocol compatibility worsen
Solution Approach 1:
The patent makes data fields multi-functional by enabling them to carry both their original information and additional sensitive data simultaneously. Through encoding techniques, the same data field structure serves multiple purposes: maintaining protocol compatibility while transmitting enhanced information content, thus achieving universality without increasing structural complexity
3Reliability
If cryptographic records are added to validate data integrity, then security and reliability are improved, but data transmission volume and processing complexity worsen
Solution Approach 1:
The patent merges cryptographic validation records with the original data fields rather than transmitting them separately. By combining the cryptographic records with the sensitive data in the same data field structure, the system achieves improved data integrity validation without proportionally increasing the total data transmission volume, as the cryptographic information shares the same transmission channel

AI summary
Methods of communicating information relating to an event are described. Elements of information relating to the event and contained in a data field are obtained and used to determine a cryptographic record. First places in the data field are filled by the elements with time information. The cryptographic record is used to fill second places in the data record. On reception of a message including the data field, the data field can be resolved into the first places and the second places. The time information associated with the event can be determined and used to establish elements of information that were combined with the time information to fill the first places. The established elements can be used to calculate a cryptographic record, which can be matched against the cryptographic record from the second places to determine that the elements of information are correct.
