A security researcher this week released the PSPtool, a software tool that “aims to lower the entry barrier for looking into the code running" on the AMD Platform Security Processor (PSP), officially known as AMD Secure Technology, and other AMD subsystems. The PSP serves similar functions to those of Intel’s Management Engine (ME) processor. However, just like the Intel ME, the secretive and undocumented nature of the chip worries security and privacy advocates.
A ovo je dobro:
Others also believe that the PSP could enable NSA backdoors. The suspicion may not be completely without merit, as Intel’s similar technology, the Management Engine was found to have an undocumented mode that was specifically developed for the NSA. As these subsystems are kept mostly undocumented and their operations secret from the user, we may still not know the full extent of these chip’s operations.
