Abstract: In various examples, a technique for verifying data integrity is disclosed that includes receiving a request to access a data block of a plurality of data blocks stored in a non-secure memory. The technique further includes identifying, in a secure memory, an authentication token associated with the data block. The technique also includes generating an updated authentication token based on the data block. The technique further includes determining whether the updated authentication token corresponds to the identified authentication token stored in the secure memory. The technique still further includes in response to determining that the updated authentication token corresponds to the identified authentication token stored in the secure memory, performing one or more operations using the data block.
