AMD SEV-SNP
Secure Encrypted Virtualization for Cloud Core NFs
Hardware-based CPU memory encryption that protects virtual machines running 6G core functions from hypervisor memory tampering and replay attacks.
Technical Explanation
AMD Secure Encrypted Virtualization-Secure Nested Paging (SEV-SNP) provides hardware memory encryption for virtualized 6G core functions. Each virtual machine running an AMF or UPF is encrypted with an isolated key managed directly by the CPU secure processor. Even if an attacker gains root access to the underlying Kubernetes host hypervisor, they cannot read virtual machine RAM, inject malicious code, or alter routing tables.
Key Functions
- Hardware AES-256 memory encryption for every running virtual machine instance
- Hardware memory integrity protection preventing hypervisor replay and memory-remapping attacks
- Cryptographic measurement and remote attestation verifying virtual machine boot state
- Zero performance overhead hardware decryption engine embedded directly on the CPU die
- Premier cloud execution architecture for public cloud hosted 6G core functions
