Five Tips To Avoid Security Errors In Product Development
By Keysight - 07 Jan, 2026 - Comments: 0

Riscure, now part of Keysight, has been helping chip vendors and device manufacturers improve the security of their products for years. The security scenario has changed a lot over time. The attacker profile evolved from individuals motivated by curiosity, with very limited resources and attack potential, to well-funded and organized adversaries with malicious motivations and the capacity to ex... » read more

TEE.fail: When Your Security System Leaves the Window Open
By Scott Best - 04 Dec, 2025 - Comments: 0

Let’s talk about a cybersecurity attack that’s been making waves: TEE.fail. TEE stands for Trusted Execution Environment. Sounds reassuring, right? But here’s the kicker: exactly what a TEE is, and what it’s supposed to guarantee, is surprisingly unclear. TEEs have been around for about a decade, but as with many things in security, the rules are more like guidelines. You might think, �... » read more

Confidential Computing To Secure AI Workloads
By Ajay Kapoor - 06 Nov, 2025 - Comments: 0

Artificial Intelligence (AI), data analytics, and high-performance computing (HPC) are transforming industries such as healthcare, finance, and manufacturing. These workloads rely on distributed systems managing massive datasets with high reliability. As computational demand grows, so does the need for end-to-end data protection. Traditional security addresses Data at Rest (DAR) and Data in ... » read more

Private Delegated Computations Using Strong Isolation
By Arm - 14 Feb, 2024 - Comments: 0

Computations are now routinely delegated to third-parties. In response, Confidential Computing technologies are being added to microprocessors offering a trusted execution environment (TEE) that provides confidentiality and integrity guarantees to code and data hosted within—even in the face of a privileged attacker. TEEs, along with an attestation protocol, permit remote third-parties to est... » read more

AI/ML Workloads Need Extra Security
By Bryon Moyer - 15 Nov, 2021 - Comments: 0

The need for security is pervading all electronic systems. But given the growth in data-center machine-learning computing, which deals with extremely valuable data, some companies are paying particular attention to handling that data securely. All of the usual data-center security solutions must be brought to bear, but extra effort is needed to ensure that models and data sets are protected ... » read more

HECTOR-V: A Heterogeneous CPU Architecture for a Secure RISC-V Execution Environment
By Technical Paper Link - 09 Nov, 2021 - Comments: 0

Summary "To ensure secure and trustworthy execution of applications, vendors frequently embed trusted execution environments into their systems. Here, applications are protected from adversaries, including a malicious operating system. TEEs are usually built by integrating protection mechanisms directly into the processor or by using dedicated external secure elements. However, both of these... » read more
