....data from the off chip region. The on chip region is pinned inside the secure CPU s cache so they cannot be evicted to external memory. Data from the off chip region may be stored in external memory. The kernel efficiently authenticates data stored in external memory using a Merkle tree [6, 9]. A Merkle tree is a tree of hashes. Each intermediate node in the tree contains an array of PA, hash pairs, where PA specifies the physical address of one of the node s children, and hash is the cryptographic content hash of that child. Each leaf node stores hashes of data in external memory, one ....
