CA 2529580

A memory device authentication method that includes providing a memory device in a host device, and providing both with an encryption algorithm, triggering the encryption algorithm during writing of data in the memory device, wherein the encryption algorithm alters 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, then verifying authenticity of the memory device by comparing the device altered data and the host altered 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.
