A first instruction to store an entity identification (ID) in a memory of a device may be received. The entity ID may be stored in the memory in response to receiving the first instruction. Furthermore, a second instruction to store a value based on a key in the memory of the device may be received. A determination may be made as to whether the value based on the key that is to be stored in the memory corresponds to the entity ID that is stored in the memory. The value based on the key may be stored in the memory of the device when the value based on the key corresponds to the entity ID.
