Random Cipher Pad Cryptography for Secure Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional one-time pads are impractical for widespread use due to the need for identical pads for each transmission, which is inefficient and vulnerable to interception, especially when using breakable Public Key Encryption for secure exchange.
Innovation Solution
The implementation of Random Cipher Pads (RCPs) that can be recursively used for encryption and decryption, with each RCP being used once and then destroyed, ensuring security through true random numbers and a process of remapping to create new, unbreakable pads for continuous secure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional one-time pads are used for encryption, then security is improved, but the complexity of key distribution and the risk of interception increase
Solution Approach 1:
The patent introduces a server as an intermediary that generates and distributes one-time pads to multiple users. Instead of users directly exchanging pads pairwise, the server acts as a central mediator that securely manages pad generation and distribution, reducing the complexity of key distribution while maintaining security.
Solution Approach 2:
The patent creates multiple copies of the same one-time pad and distributes them to different users through the server. This allows the same pad to be used by multiple users for encrypting their communications, eliminating the need for each user pair to have unique pads while maintaining the security properties of one-time pads.
2Reliability
If conventional one-time pads are used for each transmission, then security is improved, but the bandwidth requirements and operational complexity increase
Solution Approach 1:
The patent makes one-time pads universal by allowing the same pad to serve multiple communication channels and users simultaneously. Instead of dedicating a unique pad to each transmission or user pair, the system enables pads to be reused across different communications, improving efficiency while maintaining security through proper pad management.
Solution Approach 2:
The system implements a lifecycle management approach where one-time pads are generated, distributed, used, and then securely discarded. The server tracks pad usage and automatically manages the disposal of used pads, reducing operational complexity and ensuring that discarded pads cannot be reused, thereby maintaining security while improving efficiency.
Data Source
AI summary
Systems and methods with multiple different modes for bidirectional data transfer of messages encrypted with Random Cipher Pads (RCPs) are disclosed. A direct mode is from one single endpoint to another endpoint in a peer-to-peer fashion. A throughput mode may be configured as a communication between endpoints with a cryptographic data server (CDS) managing communications and additional encryption between the endpoints. The CDS further encrypts the messages such that there is a peer-to-peer encryption between the source endpoint and the CDS and a different peer-to-peer encryption between the CDS and destination endpoints. The throughput mode may also be configured as a broadcast communication between a sender and multiple destinations, each with its own different RCP encryption. A router-to-router mode may be thought of as a specific type of peer-to-peer transfer where the peers on each end are routers, servers, Virtual Private Network servers, and gateways rather than user endpoints.
