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

Performance Implications for Multi-Core RISC-V Systems with Dedicated Security Hardware
By Technical Paper Link - 18 Apr, 2022 - Comments: 0

Abstract "The RISC-V instruction set architecture (ISA) is a promising open-source architecture supporting the Open Era of Computing. As RISC-V matures, consumers, industry leaders, and nation states are looking at the potential benefits RISC-V offers –especially for secure systems which may require privileged architecture implementations, physical memory protection (PMP), or trusted executi... » read more

Cybersecurity For Cars Starts With Chips And IP
By Dana Neustadter - 06 Jan, 2022 - Comments: 0

The automotive industry is undergoing a significant transformation. Cars are becoming more sophisticated and valuable with increased connectivity and capabilities to provide a better user experience. They are also collecting and transmitting more and more sensitive data and thus are becoming very attractive targets for attacks. Cybercrime in the automotive industry is growing rapidly. How bad i... » 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

Isolate Security-Critical Applications On Zynq UltraScale+ Device
By Xilinx - 01 Dec, 2020 - Comments: 0

Implementing a TEE on the Zynq UltraScale+ platform (RFSoCs and MPSoCs) greatly reduces the attack surface of security-critical applications. Explore this white paper to find out • What a TEE is • How the requirements for a TEE are easily met on the Zynq UltraScale+ platform • Why a TEE is needed, even if hypervisors are used • An example architecture of Prove & Run’s Proven... » read more

All-in-One Vs. Point Tools For Security
By Bryon Moyer - 03 Sep, 2020 - Comments: 0

Security remains an urgent concern for builders of any system that might tempt attackers, but designers find themselves faced with a bewildering array of security options. Some of those are point solutions for specific pieces of the security puzzle. Others bill themselves as all-in-one, where the whole puzzle filled in. Which approach is best depends on the resources you have available and y... » read more

Security Verification For Processor-Based SoCs
By Ruud Derwig - 02 Apr, 2020 - Comments: 0

By Ruud Derwig and Nicole Fern Security in modern systems is of utmost importance. Device manufacturers are including multiple security features and attack protections into both the hardware and software design. End-product system security, however, cannot be guaranteed by using a secure processor alone. The final product security results not only from using proven, secure hardware component... » read more
