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.

Abstract: Electronic devices are adapted to facilitate execution of software signed by more than one entity. According to one example, an electronic device can store software including a hash table segment. The hash table segment can include at least one hash entry, a first signature and first certificate chain from a first entity for the at least one hash entry, and a second signature and second certificate chain from a second entity for the at least one hash entry. The electronic device may validate the first and second signatures. If both the first and second signatures are validated, the electronic device can execute the software. Other aspects, embodiments, and features are also included.
