Secure Networking With MACsec, IPsec, And TLS
By Bart Stevens - 06 Feb, 2025 - Comments: 0

As digital networks grow in complexity, securing data in transit has become a top priority. Cyber threats, ranging from man-in-the-middle attacks to large-scale data breaches, make strong encryption and authentication mechanisms essential. But network security is not a one-size-fits-all solution. Instead, it operates at different layers of the OSI model, with each layer offering unique protecti... » read more

Cryptography Does Not Equal Security
By Bart Stevens - 09 Jan, 2025 - Comments: 0

At Rambus, we often receive RFIs, RFPs and RFQs for security silicon IP cores to be used in our customer’s next semiconductor product. Such requests often contain a long shopping list of required cryptographic algorithms, their modes of operation, their key lengths or strengths and performance and sizing requirements. Depending on the target segment, additional requirements such as robustness... » read more

Securing AI In The Data Center
By Bart Stevens - 09 May, 2024 - Comments: 0

AI has permeated virtually every aspect of our digital lives, from personalized recommendations on streaming platforms to advanced medical diagnostics. Behind the scenes of this AI revolution lies the data center, which houses the hardware, software, and networking infrastructure necessary for training and deploying AI models. Securing AI in the data center relies on data confidentiality, integ... » read more

Safeguarding IoT Devices With SESIP And PSA Certified Root Of Trust IP
By Bart Stevens - 11 Mar, 2024 - Comments: 0

IoT is everywhere. By the end of 2024, it’s forecasted that there will be a staggering 207 billion IoT devices in the world, that’s 25 each for every human being on Earth. The connectivity of IoT devices brings great value for consumers and businesses alike, but with great connectivity comes greater vulnerability to a wide variety of malicious attacks from cyber criminals. IoT devices ar... » read more

Side-Channel Attack Protection For Quantum Safe Cryptography
By Bart Stevens - 04 Jan, 2024 - Comments: 0

A recent Reuters Special Report discussed the race between the US and China to protect digital assets and communications from the potential threat posed by quantum computers. Cryptographically relevant quantum computers, those that are powerful enough to crack existing public key-based encryption methods, could compromise military, economic, and personal information across the globe. While the ... » read more

Getting Ready For The Quantum Computing Era: Thoughts On Hybrid Cryptography
By Bart Stevens - 07 Dec, 2023 - Comments: 0

Once quantum computers, more specifically Cryptographically Relevant Quantum Computers (CRQCs), have become powerful and reliable enough, they will enable adversaries to break current asymmetric encryption, placing important data and assets at risk. New digital signatures and key encapsulation mechanisms (KEMs) are needed, and while considerable progress has been made in recent years to develop... » read more

Securing AI/ML Training And Inference Workloads
By Bart Stevens - 02 Nov, 2023 - Comments: 0

AI/ML can be thought about in two distinct and essential functions: training and inference. Both are vulnerable to different types of security attacks and this blog will look at some of the ways in which hardware-level security can protect sensitive data and devices across the different AI workflows and pipelines. The security challenges encountered with AI/ML workloads can be addressed by i... » read more

Draft Standards For Quantum Safe Cryptography Are Here
By Bart Stevens - 07 Sep, 2023 - Comments: 0

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
By Bart Stevens - 03 Aug, 2023 - Comments: 0

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
By Bart Stevens - 01 Jun, 2023 - Comments: 0

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
