Abstract:
Memory security technologies are described. An example processing system includes a processor core and a memory controller coupled to the processor core and a memory. The processor core can receive a content read instruction from an application. The processor core can identify a cache line (CL) from a plurality of CLs of a cryptographic cache block (CCB) requested in the content read instruction. The processor core can load, from a cryptographic tree, tree nodes with security metadata. The processor core can retrieve, from the memory, the CCB. The processor core can generate a second MAC from the CCB. The processor core can compare the first MAC with the second MAC. The processor core can decrypt the CCB using security metadata when the first MAC matches the second MAC. The processor core can send at least the identified CL from the decrypted CCB to the application.

Claim (Index 5):
The processor of  claim 2 , wherein the processor core is further to:\n verify, using the first MAC, that encrypted data in the memory was not modified while resident in the memory; and verify, using the counter data, that the VER data in the memory was not modified while resident in the memory.
