PQConnect: automated post-quantum end-to-end tunnels
PQConnect is a post-quantum end-to-end tunneling protocol that
automatically protects all packets between clients that have installed
PQConnect and servers that have installed and configured PQConnect.
Like VPNs, PQConnect does not require any changes to higher-level
protocols and application software. PQConnect adds cryptographic
protection to unencrypted applications, works in concert with existing
pre-quantum applications to add post-quantum protection, and adds a
second application-independent layer of defense to any applications
that have begun to incorporate application-specific post-quantum
protection.
Unlike VPNs, PQConnect automatically creates end-to-end tunnels to any
number of servers using automatic peer discovery, with no need for the
client administrator to configure per-server information. Each server
carries out a client-independent configuration step to publish an
announcement that the server’s name accepts PQConnect connections. Any
PQConnect client connecting to that name efficiently finds this
announcement, automatically establishes a post-quantum point-to-point
IP tunnel to the server, and routes traffic for that name through that
tunnel.
