How does VT virtual memory work?
The token implements an almost standard “demand paging” mechanism between the token memory and secondary storage. Before moving a page to secondary storage, the page is encrypted and authenticated with the token high speed cryptographic accelerator . The secondary storage can be either some standard non secured static RAM linked to the coprocessor or the program’s main memory. When a page is retrieved, it is checked for tampering and then decrypted before being used.
