The processing hardware is to receive an encrypted data segment with a validator and derive a decryption key using the secret value and a plurality of entropy distribution operations. The processing hardware is further to verify, using the received validator, that the encrypted data segment has not been modified. The processing hardware is further to decrypt the encrypted data segment using the decryption key to produce a decrypted data segment responsive to verifying that the encrypted data segment has not been modified.
