Poster
.qtm is a novel, open, self-contained file format designed for post-quantum protection of critical documents. It embeds post-quantum encryption (Kyber), digital signatures (Dilithium), and access policies into each file, ensuring long-term integrity and sovereignty — even offline and without PKI. This poster illustrates the architecture, standardization path (ETSI/IETF), and comparative features vs CMS, OpenPGP, and COSE, and highlights its applicability across Telco Cloud, data retention, compliance, and edge scenarios.
