Sessionless Dynamic Encryption Protocol for Quantum-Resistant Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current secure communication protocols, such as SSL/TLS, are vulnerable to quantum crypto-analysis and place heavy processing demands due to reliance on asymmetric encryption and static-digitized encryption keys, requiring costly and complex key management.
Innovation Solution
The Dynamic Packet Encryption Protocol (DPEP) uses a Digitally Unclonable Function (DUF) to establish a sessionless, cryptographically secured connection by generating unique, dynamically changing symmetric encryption keys for each packet, eliminating the need for session keys and asymmetric algorithms, and employing hashing and symmetric encryption for authentication and encryption.

Engineering Contradiction Analysis
1Reliability
If asymmetric encryption algorithms such as RSA are used for secure communication, then security is improved, but processing demands and key management costs increase significantly
Solution Approach 1:
The patent segments the encryption process into two distinct phases: asymmetric key exchange for initial security establishment, followed by symmetric encryption for actual data transmission. This segmentation allows each algorithm to be used only where it is most effective, reducing overall processing demands while maintaining security.
Solution Approach 2:
The patent uses symmetric encryption keys as a simplified copy or alternative to complex asymmetric encryption for the bulk of data transmission. Once the secure channel is established via asymmetric methods, the symmetric key serves as a lighter-weight mechanism that replicates the security function without the computational overhead.
2Device complexity
If static-digitized encryption keys are used for secure communication, then key management is simplified, but susceptibility to quantum crypto-analysis increases
Solution Approach 1:
The patent implements dynamic key generation where symmetric encryption keys are generated anew for each communication session rather than using static keys. This dynamic approach ensures that even if one key is compromised, previous and future communications remain secure, providing resistance against quantum crypto-analysis while maintaining manageable key processes.
Solution Approach 2:
The patent changes the temporal parameter of key usage from static (reusable) to dynamic (ephemeral). By making keys time-limited and session-specific, the system achieves quantum resistance without complicating key management, as keys are automatically discarded after use rather than requiring long-term storage and rotation.
3Reliability
If session keys are exchanged for secure communication, then encryption security is improved, but the authentication and key exchange process becomes more complex
Solution Approach 1:
The patent merges the authentication and key exchange processes into a unified asymmetric encryption framework. The digital signature verification serves dual purposes: authenticating the identity of the communicating party and simultaneously establishing the symmetric session key. This eliminates separate authentication and key exchange steps, reducing overall process complexity.
Solution Approach 2:
The asymmetric encryption mechanism is designed to perform multiple functions simultaneously: authentication, key exchange, and encryption setup. By making the asymmetric encryption system universal, the patent eliminates the need for separate protocols for each function, thereby simplifying the overall authentication and key management process while maintaining strong security.
