Problem:
IoBT nodes often lose connectivity with centralized Public Key Infrastructure (PKI), leaving them vulnerable to key compromise, replay attacks, and confidentiality breaches when operating offline.

Goal:
Design a decentralized and lightweight key management scheme that ensures secure communication even under network partitions.

Proposed Solution & Tasks:
Implement a RAM-only key storage system for tactical nodes (keys vanish if devices are captured).
Develop a peer-to-peer ephemeral certificate exchange system based on self-issued credentials.
Integrate elliptic-curve lightweight cryptography (e.g., Curve25519, ChaCha20) for constrained devices.
Simulate adversarial scenarios such as node capture and network jamming to test resilience.

Evaluation Criteria:
Key compromise resistance (measured by % of scenarios where captured nodes reveal useful credentials).
Cryptographic overhead (CPU and memory usage).
Communication resilience in partitioned networks (latency, delivery ratio).
