Following user outcry, AMD reinstates memory encryption in consumer CPUs

AMD has reinstated memory encryption protections in its consumer CPUs following significant user outcry. The feature, known as Transparent Secure Memory Encryption (TSME), was silently removed from consumer Ryzen processors, prompting backlash from users who had come to rely on its security against physical attacks. TSME encrypts all data stored in memory, rendering it inaccessible to adversaries attempting cold boot attacks or other intrusions requiring physical access to the hardware. AMD initially introduced TSME to its high-end CPUs approximately a decade ago and subsequently expanded its availability to lower-end consumer processors, including the Ryzen line, which are typically priced below their professional counterparts. The removal of this protection from consumer chips was not announced and was difficult to detect on Windows systems, requiring advanced technical steps to identify on Linux. AMD had previously declined to comment on the change last week. The company's decision to reintroduce TSME addresses concerns raised by security experts and consumers regarding the unexpected removal of a valued security measure.
