Introduction EchoPulse is a symbolic-logic-driven KEM architecture optimized for low RAM/ROM usage and real-time embedded environments. It addresses modern post-quantum challenges using mutation-dynamic graph encoding for key generation and encapsulation. 2. Key Features - RAM usage under 9KB - ROM footprint under 15KB - AI-adaptive mutation paths - Built-in session replay protection - High resistance to side-channel analysis 3. Security Considerations EchoPulse integrates symbolic mutation logic with post-quantum principles, complicating adversarial prediction and key recovery. It is particularly robust against pattern analysis, timing inference, and memory probing. 4. IANA Considerations This document has no IANA actions. 5. References None yet formalized. Appendix A. Acknowledgements This draft was generated with AI assistance under a multi-role verification model and symbolic simulation framework.
