AMD reinstates memory encryption in consumer Ryzen CPUs after user backlash
By
Dan Goodin
Summary
AMD has reversed its decision to remove Transparent Secure Memory Encryption (TSME) from consumer Ryzen processors after significant user backlash. TSME encrypts all memory contents, protecting against physical attacks like cold boot attacks. AMD had silently stripped this feature from consumer CPUs, which critics saw as a tactic to push users toward more expensive chips. Following the outcry, AMD reinstated the security feature in consumer-grade processors.

· 4 pulledConsumer AMD CPUs will once again offer encryption protections against physical attacks after facing user backlash for silently removing the feature.
AMD stripped the protection, known as TSME, from consumer Ryzen processors.
TSME encrypts the entire contents stored in memory, making the data useless to adversaries performing cold boot attacks and similar intrusions requiring physical access.
Critics saw the move as an underhanded way to steer them toward more costly chips.
