As the need for data security increases, the need to support both encrypted data and less sensitive data within the same system is also on the rise. One approach for providing so-called red/black separation of sensitive and encrypted data in embedded computer systems is the use of partitioning operating systems such as MILS (Multiple Independent Levels of Security/Safety). For some users, though, a software-based partition solution is unappealing, because of concerns about robustness, design risks, or the associated costs of commercial operating systems, which have to undergo a rigorous National Security Agency (NSA) certification process.
