Abstract
A memory subsystem includes a memory interface for accessing a non-volatile memory (NVM), a host interface for communicating with a host, and a processor. The processor is configured to calculate a signature over program code that is used by the host and is stored in the NVM, to verify, upon detecting a boot process performed by the host, whether the boot process is legitimate, and, only if the boot process was verified to be legitimate, to provide the signature to the host for authentication to a remote server.
