Abstract: Aspects of the present disclosure involve a method, a system and a computer readable memory to perform a secure update of a target device, including communicating an update instruction to the target device, generating one or more data values using the update instruction, generating a first authentication value using the data value(s), receiving a second authentication value from the target device, wherein the second authentication value is generated by the target device in response to the update instruction, and determining whether the secure update has been successful based on a comparison of the first authentication value and the second authentication value.
