RETBLEED: New Spectre-BTI Attack (ETH Zurich)
By Technical Paper Link - 13 Jul, 2022 - Comments: 0

New Spectre-BTI attack that "leaks arbitrary kernel memory." It's detailed in this research paper titled “RETBLEED: Arbitrary Speculative Code Execution with Return Instructions” from researchers at ETH Zürich. Mitigations are available. Abstract "Modern operating systems rely on software defenses against hardware attacks. These defenses are, however, as good as the assumptions they m... » read more

Implementing Memory Encryption To Protect Data In Use
By Rocky Zhang - 11 Jul, 2022 - Comments: 0

In my blog “The Methods of Memory Encryption to Protect Data in Use,” I discussed how the XTS/XEX mode of encryption was the appropriate choice for protecting data stored in and accessed from memory, also known as, protecting data in use. As a quick recap, XTS/XEX uses two keys, one key for block encryption, and another key to process a “tweak.” The tweak ensures every block of memory i... » read more

Security Risks Widen With Commercial Chiplets
By Ed Sperling - 07 Jul, 2022 - Comments: 0

The commercialization of chiplets is expected to increase the number and breadth of attack surfaces in electronic systems, making it harder to keep track of all the hardened IP jammed into a package and to verify its authenticity and robustness against hackers. Until now this has been largely a non-issue, because the only companies using chiplets today — AMD, Intel, and Marvell — interna... » read more

A New Phase In The Journey To Trustworthy Electronic Products
By Andreas Kuehlmann - 07 Jul, 2022 - Comments: 0

Semiconductor chips drive our everyday lives – and our global economy – in more ways than any of us could have envisioned when Tortuga Logic was founded in 2014. And similarly, the importance of hardware security has grown dramatically beyond what anyone could have predicted at that time. This has led us to redouble our effort to help the industry develop trustworthy products in the next ph... » read more

Protecting ICs Against Specific Threats
By Ed Sperling - 18 May, 2022 - Comments: 0

Identifying potential vulnerabilities and attack vectors is a first step in addressing them. Anders Nordstrom, security application engineer at Tortuga Logic, talks with Semiconductor Engineering about the growing risk of remote hardware attacks, what to do when a chip is hacked, and where to find the most common weaknesses for chips. » read more

Complex Chips Make Security More Difficult
By John Koon - 07 Apr, 2022 - Comments: 0

Semiconductor supply chain management is becoming more complex with many more moving parts as chips become increasingly disaggregated, making it difficult to ensure where parts originated and whether they have been compromised before they are added into advanced chips or packages. In the past, supply chain concerns largely focused primarily on counterfeit parts or gray-market substitutions u... » read more

Common Weakness Enumeration
By Ed Sperling - 06 Apr, 2022 - Comments: 0

Understanding potential design vulnerabilities up front can help prevent future cyberattacks. Jason Oberg, CTO at Tortuga Logic, talks with Semiconductor Engineering about why CWE is so important, when it needs to be considered, and why no hardware design is completely bulletproof. » read more

Why It’s So Difficult — And Costly — To Secure Chips
By Ed Sperling - 02 Dec, 2021 - Comments: 0

Rising concerns about the security of chips used in everything from cars to data centers are driving up the cost and complexity of electronic systems in a variety of ways, some obvious and others less so. Until very recently, semiconductor security was viewed more as a theoretical threat than a real one. Governments certainly worried about adversaries taking control of secure systems through... » 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
