Thalorin COMSEC & Post-Quantum is a compliance management platform designed to address simultaneous cryptographic transitions in defense and national security environments. The platform tracks multiple concurrent modernization programs including the Department of Defense transition from legacy EKMS (Electronic Key Management System) to KMI (Key Management Infrastructure), NSA CNSA 2.0 post-quantum cryptography adoption requirements, field programmable encryption device deployments, and coalition cryptographic coordination across allied nations. The platform provides account-level tracking for EKMS to KMI migration with visibility into fiscal year 2027 timeline targets and hybrid environment support. It includes system inventory mapping against post-quantum cryptography requirements with deadline compliance tracking for CNSA 2.0 mandates, which require new NSS systems to follow CNSA 2.0 by January 1, 2027, and equipment transitions to complete by December 31, 2030. The solution addresses algorithm migration planning from RSA and elliptic curve cryptography to quantum-resistant alternatives including ML-KEM for key encapsulation, ML-DSA for digital signatures, and enhanced hash functions. It provides audit trail capabilities for over-the-air cryptographic updates to field programmable COMSEC devices such as RESCUE, which achieved NSA High Assurance certification in October 2024. The platform includes cross-national cryptographic configuration tracking for coalition operations and convergence planning capabilities that optimize sequencing across simultaneous modernization programs to avoid double migrations and maintain interoperability.
