Segregated cores or virtual processors within a processor establish at least two separate encryption paths via software virtualization. Guest operating systems and encryption applications operate on input data with an enforced level of synchronicity. Output is compared to determine if each encryption path arrives at the same encrypted output. If the outputs are identical, the encrypted data is passed on; if not, an error report is generated. No individual vulnerability may produce a single point of failure to produce erroneously encrypted or unencrypted output.
