Post-quantum cryptography
Migrating systems off classic RSA and ECDH before harvest-now-decrypt-later traffic becomes readable. Hybrid key exchange, quantum-resistant signatures, and protocol design.
Founder · GhostKey Development
Kyeson Utley is the founder of GhostKey Development, a Texas-based engineering firm that builds post-quantum, cryptocurrency, and covert-network systems, and breaks them before anyone else can.
Kyeson Utley is a security engineer who spent years in blockchain forensics, tracing stolen cryptocurrency for fraud victims. Following the money through mixers, bridges, and exchange wallets showed exactly where digital-asset systems fail. Kyeson founded GhostKey Development to build systems that don't get robbed in the first place.
At GhostKey, Kyeson Utley leads the firm's post-quantum cryptography, crypto-engineering, and offensive-security work. That covers quantum-resistant protocol design, custody and signing infrastructure, smart-contract and cryptographic audits, in-house penetration testing, and Tor and I2P infrastructure for clients who can't afford a leak.
Kyeson also writes GhostKey's Field Notes, short pieces of general doctrine on post-quantum migration, operational security, and key custody. Kyeson's personal site is kyesonutley.com.

Tracing stolen funds across chains and through mixers and bridges. That investigative background now shapes how GhostKey designs custody systems.
