The End of RSA and ECC? How PUF-Based PQC is Redefining Cybersecurity

The rise of quantum computing is set to transform industries, but it also introduces a severe security crisis for modern cryptographic systems. Encryption methods that have safeguarded sensitive information for decades—such as RSA (Rivest-Shamir-Adleman) and Elliptic Curve Cryptography (ECC)—are now vulnerable to quantum attacks.

The urgency to adopt Post-Quantum Cryptography (PQC) has intensified due to concerns over the "harvest now, decrypt later" strategy. Adversaries can collect encrypted data today and decrypt it in the future when quantum computers become sufficiently advanced.

To address this looming challenge, eMemory Technology Inc. and its subsidiary

PUFsecurity have introduced the world’s first PUF-based PQC solution. By integrating Physical Unclonable Function (PUF) technology with quantum-resistant cryptographic algorithms, they have set a new benchmark for secure computing.

Understanding the Quantum Computing Threat

Why Traditional Cryptography is at Risk

Modern encryption methods rely on the mathematical difficulty of certain problems. However, quantum computers can efficiently solve these problems using specialized algorithms:

Traditional Cryptographic Algorithm	Quantum Algorithm That Breaks It	Estimated Time to Break Encryption
RSA (2048-bit)	Shor’s Algorithm	Minutes to Hours
ECC (256-bit)	Shor’s Algorithm	Minutes to Hours
AES-128	Grover’s Algorithm	Quadratically Reduced Time
AES-256	Resistant to Quantum Attacks	Not currently breakable

Shor’s Algorithm can efficiently factor large prime numbers, making RSA and ECC obsolete in a post-quantum world.

What is Post-Quantum Cryptography (PQC)?

The Shift Toward Quantum-Resistant Algorithms

PQC refers to encryption techniques designed to withstand attacks from both classical and quantum computers. These algorithms use different mathematical approaches, such as:

• Lattice-based cryptography (e.g., Kyber, Dilithium)

• Hash-based cryptography (e.g., SPHINCS+)

• Code-based cryptography (e.g., McEliece)

• Multivariate polynomial cryptography

The U.S. National Institute of Standards and Technology (NIST) has been leading the effort to standardize PQC algorithms. In July 2022, NIST selected four key PQC candidates:

Algorithm	Cryptographic Purpose	Security Basis
Kyber	Key encapsulation	Lattice-based
Dilithium	Digital signatures	Lattice-based
Falcon	Digital signatures	Lattice-based
SPHINCS+	Digital signatures	Hash-based

What is Physical Unclonable Function (PUF) Technology?

How PUF Works

Physical Unclonable Functions (PUF) leverage the natural variations in semiconductor manufacturing to create unique, unclonable digital fingerprints for each chip. These variations occur at the atomic level and cannot be replicated, making PUF an ideal solution for secure key generation and authentication.

Feature	Description
Intrinsic Security	No need for key storage, reducing attack surfaces
Non-Clonable	Unique per-chip, based on silicon variations
Tamper-Resistant	Impossible to replicate or extract keys
Low Power Consumption	Suitable for resource-constrained IoT and AI chips

NeoPUF: A Quantum-Secure PUF Solution

NeoPUF, developed by eMemory, enhances conventional PUF security by introducing quantum tunneling mechanisms in silicon, ensuring even higher randomness and resilience.

Key Benefits of NeoPUF

How eMemory and PUFsecurity’s PUF-Based PQC Works

The PUF-based PQC solution developed by eMemory and PUFsecurity combines PUF-generated randomness with NIST-selected PQC algorithms (Kyber & Dilithium).

How the PUF-Based PQC Solution Works

1. NeoPUF generates a unique entropy source on-chip

2. Kyber (ML-KEM) encapsulates encryption keys
