Abstract
Provided is an arbitrary automation system for secure communications. The system includes a utility device configured for processing critical data associated with the arbitrary automation system, the critical data being structured in accordance with utility device access levels. A key management module (i) provides a data protection key (DPK) for protecting the critical data in accordance with each of the utility device access levels and (ii) generates a user key encryption key (UKEK) for encrypting the DPK based upon the device access levels. The system additionally includes a software module configured for masking an execution state of software within the utility device and the key management module via principles of evasion and resistance.
