PaxQubit

PaxQubit · PyeongJeong Technology Co., Ltd.

From NAND to Qubits.

Hardened, standards-compliant error-correction & encryption IP — FPGA & ASIC ready, built by the engineers who design storage silicon.

One vendor, the full coding-theory spectrum

Error correction, cryptography, and quantum — under one roof

Classical ECC

BCH · QC-LDPC

Deterministic and soft-decision error correction for NAND, SSD and communications.

Cryptography

AES-256 · PBKDF2

Standards-compliant encryption and key derivation for data at rest and in flight.

Quantum

qLDPC

Real-time syndrome decoding for quantum error correction.

Storage Security Stack

A single datapath, key unwrap to NAND protection

PaxQubit ships every block of the secure-storage datapath — no multi-vendor integration.

01

PBKDF2

Unwraps the media key from a passphrase

02

AES-256-XTS

Encrypts data sector by sector

03

BCH / QC-LDPC

Corrects NAND bit errors

Why PaxQubit

From authentication to device lifetime

Authentication

Brute-force-resistant keys

PBKDF2-HMAC key stretching (salt + tunable iterations) — ~0.1 s for the user, years for an attacker. RFC 8018 / NIST SP 800-132.

Full datapath

One-vendor secure storage

PBKDF2 → AES-XTS → BCH/LDPC, with the SHA core shared for eMMC RPMB — one vendor, less area and verification.

Device lifetime

Longer NAND lifetime

Soft-decision QC-LDPC and high-strength BCH extend TLC/QLC NAND endurance and retention margins, keeping drives in service longer.

Standards

Silicon-grade & compliant

FPGA & ASIC-ready RTL aligned to FIPS, NIST, IEEE 1619, 3GPP and JEDEC.

Standards & compliance targets

FIPS 197NIST SP 800-38IEEE 1619PKCS#5 / RFC 80183GPP NRJEDEC NAND
