Chip Security Now Depends On Widening Supply Chain
By Ann Mutschler - 01 Aug, 2024 - Comments: 0

Securing chips is becoming more challenging as SoCs are disaggregated into chiplets, creating new vulnerabilities that involve hardware and software, as well as multiple entities, and extending threats across a much broader supply chain. In the past, much of the cyber threat model was confined to either hardware or software, and where multiple vendors were involved, various chips were separa... » read more

Security Focus Widens To HW, SW, Ecosystems
By Ann Mutschler - 02 Jul, 2024 - Comments: 0

Hardware security strategies are pushing much further left in the chip design flow as the number of vulnerabilities in complex designs and connected devices continues to grow, taking into account potential vulnerabilities in both hardware and software, as well as the integrity of an extended global supply chain. These approaches leverage the speed of fixing problems in software, and the effe... » read more

Data Center Security Issues Widen
By Adam Kovac - 04 Apr, 2024 - Comments: 0

The total amount of data will swell to about 200 zettabytes of data next year, much of it stored in massive data centers scattered across the globe that are increasingly vulnerable to attacks of all sorts. The stakes for securing data have been rising steadily as the value of that data increases, making it far more attractive to hackers. This is evident in the scope of the attack targets —... » read more

Securing DRAM Against Evolving Rowhammer Threats
By Aharon Etengoff - 07 Mar, 2024 - Comments: 0

Advanced process nodes and higher silicon densities are heightening DRAM's susceptibility to Rowhammer attacks, as reduced cell spacing significantly decreases the hammer count needed for bit flips. Rowhammer exploits DRAM’s single-capacitor-per-bit design to trigger bit flips in adjacent cells through repeated memory row accesses. This vulnerability allows attackers to manipulate data, re... » read more

Security Becoming Core Part Of Chip Design — Finally
By Ann Mutschler - 07 Dec, 2023 - Comments: 1

Security is shifting both left and right in the design flow as chipmakers wrestle with how to build devices that are both secure by design and resilient enough to remain secure throughout their lifetimes. As increasingly complex devices are connected to the internet and to each other, IP vendors, chipmakers, and systems companies are racing to address existing and potential threats across a ... » read more

Five Things You Should Know To Avoid The Most Common Security Errors
By Riscure - 03 Aug, 2022 - Comments: 0

Since 2001, Riscure has been helping chip vendors and device manufacturers improve the security of their products. Over the years, the security scenario has changed a lot. The attacker profile evolved from individuals motivated by curiosity, with very limited resources and attack potential, to well-funded and organized adversaries with dark motivations and the capacity to execute very sophistic... » read more

Building A Robust Hardware Security Program
By Tortuga Logic - 01 Jun, 2022 - Comments: 0

Even mature chip development teams and processes aren’t immune to security errors. While many semiconductor and hardware manufacturing organizations have mature development processes, existing security testing practices, and formal signoff requirements, the complexity and duration of the chip lifecycle creates many opportunities for security issues to be overlooked. Semiconductors now play... » read more

Building Security Into ICs From The Ground Up
By John Koon - 05 May, 2022 - Comments: 0

Cyberattacks are becoming more frequent and more sophisticated, but they also are starting to compromise platforms that until recently were considered unbreakable. Consider blockchains, for example, which were developed as secure, distributed ledger platforms. All of them must be updated with the same data for a transaction to proceed. But earlier this year a blockchain bridge platform calle... » read more

Anti-Tamper Benefits Of Encrypted Helper-Data Images For PUFs
By Rambus - 01 Dec, 2021 - Comments: 0

PUFs are mixed-signal circuits which rely on variations unique to a specific chip to self-generate a digital “fingerprint.” Most PUFs require a “helper-data” image that is generated during the initial digitization process, also known as Enrollment. Leveraging the chip-unique transformation function of PUFs and encrypted helper data, an unclonable challenge-response mechanism can be impl... » read more

Importance Of Programmability In Next-Generation Security Appliances
By Xilinx - 01 Dec, 2021 - Comments: 0

Traditional methods of deploying network security through software-based firewalls do not scale because the latency and bandwidth requirements cannot be addressed. The flexibility and configurability of Xilinx adaptive devices combined with IP and tool offerings significantly improves security processing performance. This white paper explores multiple firewall architectures, which include so... » read more
