Riset-disertasi

Riset-1 (ROI + Ascon via CoAP) → Paper Conference [port 5001 - 6001]

Tujuan: menunjukkan keunggulan selective encryption untuk multimedia di IoT. Evaluasi:

1. Kinerja sistem

• CPU usage / execution time enkripsi (per gambar, per resolusi).
• Latency end-to-end (ClientA → ServerB).
• Payload size (bytes dikirim).
• Retransmisi (via pcap).

1. QoE (Quality of Experience)

• SSIM/PSNR area non-ROI (harus ≈1 / ∞ → fidelity utuh).
• SSIM area ROI (rendah → privasi terlindungi).

1. Cryptographic footprint

• Distribusi bytes terenkripsi antar gambar/resolusi.

1. Privasi visual

• Apakah ROI (misalnya wajah) tak terbaca setelah enkripsi.

Riset-2 (App-layer vs Transport-layer vs Hybrid) → Paper Q1 [port 5002 - 6002]

Tujuan: membandingkan keamanan di layer aplikasi (ROI+Ascon) vs layer transport (OSCORE) vs kombinasi keduanya (cross layer). 1. Perbandingan overhead antar layer

  * Latency (CoAP vs OSCORE vs ROI+Ascon+OSCORE).
  * Payload size (besar header tambahan OSCORE).
  * CPU usage: ROI+Ascon (app) vs OSCORE (transport).

2. Reliabilitas komunikasi

  * Packet retransmission / packet loss.
  * Goodput (gambar/MBps efektif).

3. Security

  * Transport: full payload protected, tapi tidak selective.
  * App-layer: selective encryption, lebih hemat.
  * Kombinasi: double protection, overhead lebih tinggi.

4. Platform diversity

  * Evaluasi di VM (GNS3) vs Raspberry Pi vs ESP32.
  * Apakah constraint hardware mempengaruhi performa signifikan.

Riset-3 (NanoCipher – AEAD baru) → Paper Q1 [port 5003 - 6003]

Tujuan: membuktikan NanoCipher sebagai AEAD ringan khusus multimedia. Evaluasi inti (kriptografi + sistem): 1. Benchmark kriptografi (MCU/CPU level)

  * Cycles/byte (ukur dengan benchmark Ascon/PRESENT/ChaCha20).
  * Throughput (MB/s).
  * Code size (flash, KB).
  * RAM usage.
  * Energy/byte (estimasi via current measurement di Raspberry Pi/ESP32).

2. Keamanan algoritma

  * Correctness: Known Answer Test (KAT).
  * Nonce misuse resistance (uji basic).
  * Konsistensi constant-time (cek dengan alat timing).

3. Perbandingan dengan cipher lain

  * Ascon.
  * PRESENT.
  * ChaCha20.
  * AES.

4. Integrasi

  * Kirim gambar (via libcoap) dengan NanoCipher.
  * Latency, payload, CPU, QoE → dibandingkan Ascon/AES/ChaCha20/PRESENT.

Riset-4 (NanoCipher + OSCORE) → Paper Q1 [port 5004 - 6004]

Tujuan: menguji apakah NanoCipher bisa jadi alternatif AEAD di OSCORE (transport security). Evaluasi: 1. Integrasi OSCORE

  * Modifikasi libcoap → NanoCipher jadi AEAD opsional di COSE.
  * Kinerja encode/decode OSCORE.

2. Perbandingan OSCORE-AES vs OSCORE-Ascon vs OSCORE-NanoCipher

  * Latency per message.
  * Payload overhead.
  * CPU usage.
  * Energy consumption.

3. Robustness

  * Correctness (uji KAT + interop message decrypt).
  * Replay protection (uji ulang id_context, sequence number).

4. Resource impact (IoT)

  * Memory footprint tambahan bila OSCORE pakai NanoCipher.
  * Apakah Raspberry/ESP32 masih muat (RAM/flash).
