Abstract
A memory device authentication method that includes providing a memory device in a host device, and providing both an encryption algorithm, triggering the encryption algorithm during writing of data in the memory device, wherein the encryption algorithm allters the written data and generates a device altered data, then storing the written data in the memory device, running the encryption algorithm in the host device on the data written in the memory device and generating a host altered data, the verifying authenticity of the memory device by comparing the device altered data and the host alerted data. An authentication device and associated system that includes a host device that comprises a unit, a first encryption algorithm that is stored in the host device, and a second encryption algorithm, identical to the first encryption algorithm, that is permanently stored in a memory of the unit.
