98 Hardware Security Failure Scenarios (NIST)
By Technical Paper Link - 03 Dec, 2024 - Comments: 0

A new technical paper titled "Hardware Security Failure Scenarios: Potential Hardware Weaknesses" was published by NIST. Abstract "Hardware is often assumed to be robust from a security perspective. However, chips are both created with software and contain complex encodings (e.g., circuit designs and firmware). This leads to bugs, some of which compromise security. This publication evaluate... » read more

Using Formal For RISC-V Security
By Ed Sperling - 19 Nov, 2024 - Comments: 0

Finding and closing up security holes is becoming more important as chips are used in safety- and mission-critical applications, but it's increasingly important for chips designed for much less costly devices, where the selling price typically doesn't warrant a significant investment in security. The problem is these devices are connected to some of the same networks, and any access points for ... » read more
