Abstract
Secure communication of data between devices includes encrypting unencrypted data at a first device by reordering unencrypted bits provided in parallel on a device bus, including data and control bits, from an unencrypted order to form encrypted data including a plurality of encrypted bits in parallel in an encrypted order defined by a key. The encrypted data may be transmitted to another device where the encrypted data is decrypted by using the key to order the encrypted bits to restore the unencrypted order thereby to reform the unencrypted data.
