Job Title:

Job Type:

Objective:

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.
