Abstract
A method of communicating securely between an application program and a secure kernel is performed by passing command requests and arguments between the application program and the secure kernel through a kernel block memory and a command block memory so that security intensive and real time intensive applications can co-exist without a security breach. The secure kernel retrieves the command requests and the arguments from an application program data memory and processes the information within the secure kernel. The secure kernel returns the processed data to the application program. All data transfers are under control of the secure kernel software, and thus numerous 'active attacks' against the security of the system are defeated.
