Cyber-Physical Security from Chip to Cloud with Post-Quantum Cryptography

In our interconnected world, systems ranging from smart cities and autonomous vehicles to industrial control systems and healthcare devices have become everyday components of our lives. This fusion of physical and digital systems has led to a term called cyber-physical system (CPS). Ubiquitous connectivity is exposing the systems to a wide range of cyber-threats and robust security measures are needed to safeguard the systems.

Securing the Chip, the Cloud and the Communications

At the heart of cyber-physical systems are the chips that control various functions. Securing these chips is crucial because compromised hardware can lead to vulnerabilities that are nearly impossible to detect. Cryptography plays a role at this level by ensuring that the communication between different components of a chip is secure and the data is protected. One of the exciting developments in chip-level security is the integration of hardware-based security features that work in tandem with cryptographic protocols. These features can include physically unclonable functions (PUFs), secure enclaves, and tamper-resistant designs. Such measures not only protect data at rest but also help prevent attacks on the chip’s operation. In the context of CPS, secure communication between devices and the cloud is paramount. Whether it’s transmitting data from sensors in an industrial setting or updating the software on an autonomous vehicle, the integrity of this communication is imperative. And, the cloud is where the data from CPS is often processed, stored, and analyzed and is a prime target for cyberattacks. Leveraging cryptography in cloud security protocols is vital to safeguarding the data and services hosted on the cloud. This ensures that even if bad actors gain access to the cloud infrastructure, they won’t be able to decipher sensitive information.

The field of cryptography is quite advanced and time-tested encryption algorithms such as RSA and ECC have been widely-deployed to ensure cyber-security of connected systems. But dedicated hardware support is very important as secure processing and management cannot be accomplished solely with software.

But the onset of quantum computing poses a significant threat to current cryptographic methods.

Post-Quantum Cryptography (PQC)

To counter the quantum threat, researchers are developing post-quantum cryptography, a new generation of cryptographic techniques that are designed to withstand attacks from quantum computers. These cryptographic methods are being designed to be quantum-resistant, ensuring that the confidentiality and integrity of data remain intact in a quantum-powered world. Post-quantum cryptographic algorithms can be employed to secure the communication channels, ensuring that data remains confidential and protected from quantum eavesdropping. Techniques like lattice-based cryptography, code-based cryptography, and hash-based cryptography offer robust security even against quantum adversaries. While PQC is in various stages of standardization currently, what customers need now are solutions that can be easily upgraded to incorporate PQC.

The ease of upgrading CPS to incorporate PQC protection is essential in order to expect rapid adoption of cyber-threat safeguards across a very wide base of systems. This means deploying embedded security systems that are PQC ready. Secure-IC offers solutions that fit this criterion.
