Abstract
A security kernel of a secure processing system for providing security management, key management and kernel security functions. The secure processing system includes two parallel subsystems, a red subsystem and a black subsystem. The red subsystem may communicate only with the kernel since this system transfers plain text data. The black subsystem may communicate with the red subsystem and also other processing systems for the transmission of cypher text data. The security kernel is a single standard interface for tasks associated with the red and black subsystems for communicating in a secure manner with one another and with other processing systems. Various security services are provided to red and black subsystem applications by a single security kernel.
