The AMD PSP (Platform Security Processor) 30 Device is a security-related hardware component in AMD processors. It provides essential security features, such as secure boot, firmware security, and cryptographic operations, helping protect systems from various types of attacks. The "30" in the name typically refers to a version or specific iteration of the PSP.

The PSP is responsible for handling secure execution environments, trusted execution environments (TEEs), and other security-related tasks on systems with AMD processors. In some cases, it may be referred to as part of AMD's Secure Technology, which is akin to Intel's Intel TXT or Intel SGX.
