Summary
👤
Senior🎓
Top SchoolJoshua Hill is an Information Security Scientist with over 20 years in the field and a decade focused on rigorous entropy evaluation for both physical and non-physical noise sources. He blends deep mathematical training (MS/PhD-level work in number theory and cryptography) with hands-on experience validating products to U.S. Federal standards like FIPS 140 and SP800-90B, including authoring test tools and substantive corrections to NIST’s reference implementations. Joshua has led and created entropy analysis groups and product offerings, produced influential technical reports for CMVP, NIAP, and NSA, and translated complex standards into practical lab procedures. He pairs cryptographic and statistical expertise with broad security engineering experience—from protocol and firmware reviews to threat analysis for payment terminals—and has a track record of improving standards and tools through detailed, field-tested feedback. An often-unsung strength is his ability to teach and communicate advanced math and crypto topics to diverse audiences, turning theoretical models into auditable, production-ready evaluations.
