AMD Restores Memory Encryption in Consumer CPUs Following User Feedback

In response to user concerns, AMD is bringing back memory encryption features in its consumer CPUs. Previously, the company had removed Transparent Secure Memory Encryption (TSME) from its Ryzen processors, a move that sparked significant backlash. TSME is designed to encrypt all data stored in memory, rendering it inaccessible to attackers who might attempt cold boot attacks or other physical intrusions. This feature was initially introduced in AMD's high-end CPUs about ten years ago and later extended to more affordable Ryzen models. Users had come to rely on this security enhancement, even though some experts argue that consumer-grade chips are less likely to face physical threats. The sudden removal of TSME from lower-end AMD CPUs went largely unnoticed by many users, especially on Windows systems, while Linux users faced challenges in identifying the change. Last week, AMD chose not to comment on the decision to eliminate the feature, but the company has now acknowledged the demand for its reinstatement.
