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 ...

A decade ago, AMD added a protection to its high-end CPUs to protect them against cold boot attacks and other types of physical exploits that siphon sensitive data out of the connected memory chips.

Without announcement, AMD has disabled the security feature TSME on certain Ryzen processors. Customers protested, AMD reacts.

The last decade-plus has seen a wealth of advancements designed to secure data at the microprocessor level, but a team of academic researchers recently punched through those defenses with a tiny ...

UPDATE 06/22: In a statement to PCMag, AMD acknowledges that a BIOS option to enable Memory Guard on certain non-PRO Ryzen 9000-series desktop processors "was previously available but was removed in a ...

VMware announced support for AMD secure encrypted virtualization-encrypted state (SEV-ES) in the latest update to its vSphere virtualization platform. SEV-ES provides hardware layer encryption of ...

Many AMD processors – but not all – can transparently encrypt and decrypt working memory. This feature, called Transparent Secure Memory Encryption (TSME), protects against very few and very specific ...

AMD appears to have yanked a memory encryption protection from consumer Ryzen chips, leaving users to play firmware detective. For those who came in late: a decade ago, AMD added Transparent Secure ...

Security researchers have built a $50 device that can bypass the confidential computing defenses of both Intel and AMD processors used in hardware powering cloud environments, thus allowing attackers ...
