Abstract: Various additional and alternative aspects are described herein. In some aspects, the present disclosure provides a method of authenticating executable images in a system-on-chip (SoC), the method comprising: storing a plurality of executable images; storing, as separate from the plurality of executable images, a signed image of hashes comprising a plurality of hashes corresponding to the plurality of executable images and a first signature; authenticating the signed image of hashes based on the first signature; and using a first hash of the plurality of hashes to authenticate a first executable image of the plurality of executable images when the signed image of hashes passes authentication.
