Consumer AMD CPUs will once again offer encryption protections against physical attacks after facing user backlash for silently removing the feature.
As Ars reported last week, AMD stripped the protection, known as TSME, from consumer Ryzen processors. Short for Transparent Secure Memory Encryption, TSME encrypts the entire contents stored in memory, making the data useless to adversaries performing cold boot attacks and similar intrusions requiring physical access.
Now you see it, now you don’t, soon you’ll see it again
About a decade ago, AMD added TSME to its high-end CPUs. Over the next few years, AMD added the protection to lower-end processors, including the consumer version of its Ryzen chips, a CPU that costs less than the Pro version. Over the years, users of these lower-end chips...
