Entropy Stream Encryption via One-Time Pad Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Securely transmitting and expanding entropy over communication channels without allowing attackers to intercept and utilize the random information for decryption or other processes, as existing methods are vulnerable to interception and frequency analysis.
Innovation Solution
Implementing a system that transmits random information using a One Time Pad (OTP) for encryption, embedding messages within the entropy stream, and using expansion vectors to securely share and expand entropy, ensuring that even if the stream is intercepted, the underlying random data remains unknown due to deterministic and random transformations.

Engineering Contradiction Analysis
1Reliability
If random information is transmitted over a communication channel, then the entropy can be shared between parties, but the transmission becomes vulnerable to interception and frequency analysis attacks
Solution Approach 1:
The patent segments the entropy stream into multiple portions and distributes them across different communication channels or time periods. This segmentation prevents attackers from intercepting the complete entropy stream needed for frequency analysis, while still enabling legitimate recipients to reconstruct the full entropy through authorized aggregation of the segmented portions.
Solution Approach 2:
The patent introduces cryptographic intermediaries such as authenticated encryption mechanisms and key derivation functions that mediate the entropy transmission process. These intermediaries ensure that even if the entropy stream is intercepted, attackers cannot perform frequency analysis without the proper authentication credentials and cryptographic keys, thus protecting the security while maintaining reliable transmission.
2Reliability
If encryption is applied to protect entropy transmission, then security is improved, but the complexity of the system increases
Solution Approach 1:
The patent dynamically adjusts cryptographic parameters such as encryption key lengths, algorithm selection, and authentication mechanisms based on the security requirements and threat level of the communication channel. This allows the system to provide strong security when needed while reducing complexity in lower-risk scenarios, thus balancing security improvement with system complexity management.
3Reliability
If entropy is expanded to increase security, then the security strength is improved, but the processing time and computational resources increase
Solution Approach 1:
The patent performs entropy expansion in advance during periods of low computational demand, pre-generating expanded entropy pools that can be quickly deployed when security operations are required. This preliminary action ensures that high-security operations have access to pre-expanded entropy without incurring processing delays during critical operations, thus improving security strength while minimizing time loss.

AI summary
A message is embedded within an entropy stream. The message is encrypted using a onetime pad (OTP) and thus looks like part of the entropy string since the OTP encrypted messages is, as long as the “pad” material and message content are known, itself random to the observer. The encrypted message contains information used to identify and/or point to relevant information in another part of the entropy stream. For example, the OTP-encrypted message may indicate the number of units of the message, and point to a position in another part of the stream where another message is located. The stream may be randomly and deterministically expanded. Other techniques encrypt a stream using standard encryption, the stream comprising messages that are deterministically OTP encrypted; expand said encryption using a byte vector/array of randomness including at least one random vector; periodically swap out at least one member from the vector; hide vector random bytes in messages and/or using the messages to direct which bytes to remove from the stream of randomness/entropy; and store a stash of randomness separately from the messages and/or pull off the random/entropy stream as directed by the messages. By using true random and determinism, we create a method of generate a known pool of randomness that, if intercepted, cannot be discovered through mathematical analysis.
