Abstract: A technique includes receiving a request to initialize a region of a memory. Content that is stored in the region is encrypted based at least in part on a stored nonce value and a key. The technique includes, in response to the request, performing cryptographic-based initialization of the memory, including altering the stored nonce value to initialize the region of the memory.
