Q-SHIFT
Security Beyond Patterns: In-Kernel Post-Quantum Live Patching. Re-engineering the cryptographic fabric of the Linux kernel in real-time.
Harvest Now,
Decrypt Later.
Modern encryption is facing an existential clock. Nation-state actors are currently executing HNDL (Harvest Now, Decrypt Later) strategies—mass capturing encrypted traffic today to decrypt it using future Quantum Computers.
Standard TLS 1.3 protects you today, but it is a transparent window to the technology of 2030. Q-Shift intercepts this timeline by injecting post-quantum cryptographic (PQC) integrity into existing flows without service interruption.
Sovereign & Stateless
Privacy-by-Design
No logs. No telemetry. Q-Shift operates within the memory boundaries of your kernel, ensuring no cryptographic material ever leaves your control.
Zero Data Storage
State is ephemeral. By leveraging AF_XDP and ring buffers, packet transformation happens in-flight with zero persistence on disk.
Local Control
Deploy on your bare-metal or private cloud. Q-Shift is infrastructure-agnostic, giving you sovereign control over your encryption gateway.
The 6 Phases of Quantum Shift
A deep-dive into the architectural mechanics of the Q-Shift kernel injection engine.
Ring-0 Intercept
eBPF/XDP hooks at the NIC driver level ensure zero-copy packet interception before the kernel stack processing begins.
SEC("xdp_qshift")
Memory Bridge
AF_XDP socket implementation facilitates ultra-low latency userspace-to-kernel communication via shared UMEM regions.
AF_XDP_ZERO_COPY
Dynamic TLS Pointer Jumper
Real-time identification and manipulation of TLS 1.3 handshake pointers to inject PQC-KEM public keys dynamically.
KEM_INJECT_V1
FIPS 203 Quantum Forge
Integration with Cisco QRNG API for high-entropy sources, feeding the FIPS 203 (ML-KEM) compliant cryptographic engine.
API_QRNG_SYNC
Dynamic MTU TCP Segmentation
Handling the increased payload size of PQC keys by re-calculating TCP segmentation and MTU windows in real-time.
TCP_RESEG_OFFLOAD
The Re-Entry
Final checksum validation using RFC 1071 standards before re-inserting the packet into the kernel’s transmit path.
XDP_PASS_VALIDATED
Deploy at the Edge
Q-Shift isn’t just a library; it’s an Invisible Cryptographic Gateway. By operating at the kernel level, it seamlessly augments standard load balancers like Nginx and HAProxy.
There is no need to recompile your applications or upgrade your entire server fleet’s OpenSSL versions. Q-Shift patches the pipe, not the application, ensuring that every packet leaving your edge is quantum-resistant by default.
