Machine for testing e.g. flash type memory in cryptographic key generation device, has comparing unit for comparing message with another message and providing validation signal if former message is identical to latter message

摘要

The machine has a storage unit for storing data, and a generating unit for generating a random number. A communication unit communicates with a product under test to transmit the random number and receive a message calculated from the data and the random number. Another storage unit stores another data, and a calculating unit calculates another message from the latter data and the random number. A comparing unit compares the messages and provides a validation signal if the former message is identical to the latter message. An independent claim is also included for a method for testing a product under test.
