Auto Sector Leads The Way In IC Security
By Ann Mutschler - 03 Apr, 2025 - Comments: 0

Concerns about chip and system security are beginning to bear fruit in some markets, driven by the overlap in safety and security in automotive applications and the growing value of algorithms and complex systems in others. But how and when that security is implemented is still all over the map, and so is its effectiveness. The reasons are as nuanced as the designs themselves, which makes it... » read more

SW-HW Co-Design Mitigation To Strengthen ASLR Against Microarchitectural Attacks (MIT)
By Technical Paper Link - 26 Feb, 2025 - Comments: 0

A technical paper titled "Oreo: Protecting ASLR Against Microarchitectural Attacks" was published by researchers at MIT. Abstract "Address Space Layout Randomization (ASLR) is one of the most prominently deployed mitigations against memory corruption attacks. ASLR randomly shuffles program virtual addresses to prevent attackers from knowing the location of program contents in memory. Microa... » read more
