**Objective**:
Design and evaluate **HQBChain**, a high-fidelity hybrid cryptographic protocol that combines **Quantum Key Distribution (QKD)**, **Post-Quantum Cryptography (Kyber, Dilithium)**, and **AES-GCM symmetric encryption** to deliver secure, scalable, and quantum-resilient blockchain communication

**Job Purpose**:

- Lead the **design, implementation, and simulation** of HQBChain for next-generation secure blockchain systems.
- Develop Python-based modules for **QKD-based key exchange**, **PQC authentication/signatures**, and **AES-GCM transaction encryption**.
- Build a **simulation-driven environment** incorporating quantum noise models (IBM Quantum), PQC benchmarks (NIST, liboqs), and blockchain transaction workloads (Hyperledger Fabric).
- Publish research outcomes, including **protocol architecture, benchmarking results, and security analysis**, in high-impact journals.

**Required Qualification**:

- Master’s or Ph.D. in **Computer Science, Cryptography, Applied Mathematics, Cybersecurity, or Quantum Information Science**.
- Strong background in **post-quantum cryptography, QKD protocols (BB84, E91), and hybrid cryptographic systems**.
- Proficiency with **Python** and cryptographic libraries

**Tools to be Familiar**:

- **Programming**: Python (mandatory); familiarity with C/C++ is a plus.
- **Simulation/Testing**: Jupyter, IBM Quantum noise models.
- **Blockchain Frameworks**: Hyperledger Fabric, Python-based blockchain simulators.

**Required Experience**
- At least **2+ years of research or development** in cryptography, protocol design, or blockchain security.
- Hands-on experience with **post-quantum algorithms** (e.g., Kyber, Dilithium, Falcon, SPHINCS+) and **QKD simulations**.
- Track record of **publishing reproducible, peer-reviewed research** with algorithmic and experimental rigor.

**Required Knowledge/Skills**
- **Hybrid cryptography** (QKD + PQC + symmetric crypto).
- **Simulation-driven security evaluation** using realistic noise models and blockchain workloads.
- **Security metrics**: key generation rates, QBER, transaction throughput, block validation latency.
- Familiarity with **quantum attack models** (eavesdropping detection, side-channel threats, adversarial modeling).
- Ability to **benchmark and optimize algorithms** for scalability in blockchain networks.
- Develop, simulate, and validate **HQBChain**, a hybrid quantum-resilient protocol for blockchain.
- Implement **QKD key exchange, PQC signatures (Dilithium), and AES-GCM encryption** in Python.
- Run simulation experiments using **IBM Quantum noise data, NIST PQC benchmarks, and Hyperledger Fabric** workloads.
- Benchmark HQBChain against **RSA/ECDSA** and **PQC-only systems**, measuring performance and resilience under quantum adversarial conditions.
- Contribute to **Scopus/SCI-indexed publications**, prepare datasets, maintain reproducible code (Git), and respond to reviewer feedback.
- Ensure **academic integrity, originality, and transparency** across all stages of the research cycle.
