Abstract: Techniques for authenticating data on a computing device are provided. An example method according to these techniques includes generating a first cryptographic output by applying a first cryptographic algorithm to each block of a first subset of the plurality of blocks of data to be authenticated, combining a last block of the first cryptographic output with a second subset of the plurality of blocks of data to generate an intermediate result, and generating an authentication output by applying a second cryptographic algorithm to the intermediate result, the second cryptographic algorithm being different than the first cryptographic algorithm.

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.
