Abstract

Various examples are directed to a host device comprising a memory system, a host device memory, and a processor. The processor is programmed to receive from the memory system a first logical-to-physical (L2P) pointer message that comprises a first L2P pointer and a first digital signature. The processor executes a cryptographic operation based at least in part on the first L2P pointer and a cryptographic key and verifies the first digital signature based at least in part on the cryptographic operation. The processor caches the first L2P pointer at the host device memory.
