A Drop-in KEM Replacement for Client Signatures in Post-Quantum SSH

The transition to post-quantum cryptography is reshaping the Secure Shell (SSH) protocol for remote administration. Post-quantum key exchange has been deployed in OpenSSH and is being standardized, while SSH authentication largely remains a signature-replacement effort. This path preserves the familiar public-key crede...

Tlcp hardening with formal analysis and post-quantum design

KEMTLCP is proposed, a post-quantum secure variant of TLCP that leverages key encapsulation mechanisms (KEMs) for both key exchange and authentication while preserving TLCP’s architectural principles through a novel explicit authentication mechanism.
