Abstract
A system can include a processor having a secure mode and a non-secure mode, and a secure module configured to respond to tokens posted by the processor in the secure mode. Each token can identify a secure asset, and source and destination addresses within secure and public address spaces. The secure module can include a memory storing secure assets identifiable by the tokens and a memory access circuit to read data from source addresses and write processed data to destination addresses. The system can further include a cryptography engine configured to process the read data using identified secure assets. The secure module can respond to tokens posted in the non-secure mode. The memory can store, with each secure asset, a respective rule defining the address spaces where the memory access circuit may read and write data. The secure module can ignore tokens that do not satisfy respective rules.
