Draft Standards For Quantum Safe Cryptography Are Here

The world of security is constantly evolving, and in the few short weeks that have passed since my last blog on What It Takes To Make An SoC Design Quantum Safe, there have been some new and exciting developments in the world of quantum safe cryptography. On August 24th, 2023, NIST published the first three draft standards for general-purpose Quantum Safe Cryptography (also known as Post-Quantu... » read more

What It Takes To Make An SoC Design Quantum Safe

When it comes to quantum computing attacks, the first question people ask is “will my design be impacted?” In the majority of cases, the answer is yes. For any device that cannot function with manually programmed symmetric keys, which is most devices, you must plan to make upgrades. The good news is that your architecture is not impacted. Secure domains remain secure domains and keys can be... » read more

Post-Quantum Cryptography: The Algorithms That Will Protect Data In The Quantum Era

There is no doubt that quantum computers will play a significant role in helping the world solve complex challenges not possible on current classical computers. However, quantum computers also pose a serious security threat. They will eventually become powerful enough to break traditional asymmetric cryptographic methods, that is, some of the most common security protocols used to protect sensi... » read more

Automotive Security: Meeting The Growing Challenges With Certified Hardware Security Module IP

Automotive systems, and the semiconductors used within them, are some of the most complex electronics seen today. The radical transformation from an isolated mechanical car to a connected software-driven car is driving the increased use of semiconductors in vehicles: these include advanced driver assistance systems (ADAS), electrification, and enhanced driver/passenger experience. More conne... » read more

Selecting The Right Root Of Trust For Your Application And Architecture

A Root of Trust is defined as the security foundation for a semiconductor or electronic system. Any secure function performed by the device or system relies in whole or in part on this Root of Trust. Based in hardware, the Root of Trust handles the cryptographic functions, stores and manages cryptographic keys, and is typically part of the secure boot process providing the foundation for the so... » read more

Securing IoT Devices With Lightweight Cryptography

The National Institute of Standards and Technology (NIST) recently announced the selection of a new family of cryptographic algorithms called ASCON, which have been developed for lightweight cryptography applications. In this blog, we will explore what lightweight cryptography is and why it is worth considering for specific Internet of Things (IoT) use cases. In summary, lightweight cryptogr... » read more

Leveraging The Benefits Of A FIPS 140 CMVP Certified Root Of Trust IP

Expectations that security IP designs meet the highest security standards are growing rapidly. As companies face increased product development costs and time pressure, choosing an IP that has been certified demonstrates not just compliance with a standard, but offers a valuable tool to reducing overall project risk. The Federal Information Processing Standard (FIPS) 140 is published by NIST,... » read more

Architecting Hardware Protection For Data At Rest, In Motion, And In Use

Planning the security architecture for any device begins with the security threat model. The threat model describes the types of attacks that the device or application may face and needs to be protected against. It is based on what attackers can do, what level of control they have over the product (i.e., remote, or direct access), and how much money and effort they are willing and able to spend... » read more

Setting The Standard For Automotive Security

Vehicle systems and the semiconductors used within them are some of the most complex electronics seen today. In the past, electronics going into vehicle systems implemented flat architectures with isolated functions controlling various components of the power train and vehicle dynamics. These electronic systems communicated primarily through legacy bus interconnect protocols, like controller ar... » read more

DPA Countermeasures Done Right

In the late nineties, Paul Kocher, Josh Jaffe, and Ben Jun published a paper that caused many across industry sectors to reconsider what cryptographic implementations should look like. They described an exploit wherein an adversary could extract secrets from a device by analyzing the power consumption or electromagnetic emittance from the device when it was executing cryptographic operations. S... » read more
