Abstract

See full text

An embodiment includes executing, by a hypervisor, a bootloader with access to a first logical partition of a non-volatile memory, the first logical partition storing a keystore. The embodiment also includes loading, by the bootloader, a kernel with access to the first logical partition of the non-volatile memory. The embodiment also includes receiving, by the bootloader, an encryption key from the keystore. The embodiment also includes performing, by the bootloader, a cryptographic algorithm using the encryption key on the kernel. The embodiment also includes executing, by the bootloader in an event that the performing of the cryptographic algorithm produces a first result, the kernel with access to the first logical partition of the non-volatile memory. The embodiment also includes halting, by the bootloader in an event that the performing of the cryptographic algorithm fails to produce the first result, booting of the kernel and generating an error message.
