I build security-critical systems and cryptographic primitives from scratch —
the fastest way to understand how something breaks is to implement, attack, then defend it.

Project What it is Stack
SecureIoT-Protocol Mutually authenticated secure channel for IoT — ephemeral X25519 + ChaCha20-Poly1305 + HKDF, sliding-window anti-replay, all crypto from scratch and RFC-validated C++17
car-security-simulator Automotive CAN-bus security platform — AUTOSAR SecOC, intrusion detection, UDS Security Access, attack simulation Python
network-traffic-analyzer PCAP parsing, protocol decoding, anomaly detection and an HTML reporting dashboard Python
stb-34.101.31 The STB 34.101.31 (Bel-T) standard — block cipher, hashing and modes, to spec C++

  • Applied cryptography — implementing primitives and protocols from scratch, validated against RFC/NIST test vectors
  • Network & traffic security — packet analysis, protocol dissection, anomaly detection
  • Embedded / automotive security — CAN bus, AUTOSAR SecOC, UDS, intrusion detection
  • Offensive security — exploit fundamentals and tooling (currently sharpening)
