A memory test system may include: a data storage device including a nonvolatile memory device, and a controller configured to control an operation of the nonvolatile memory device; and a test device configured to: request a test to the data storage device; request, to the data storage device, an output of a variable to be generated through driving of a firmware for performing the test, while the test is performed in the data storage device; and determine whether the firmware is normally driven based on the variable outputted from the data storage device.

Memory test system and an operating method thereof

A method and apparatus for authenticating packets in a controller area network (CAN) are disclosed. The method includes transmitting messages using a mixture of message authentication codes (MACs) in a controller area network (CAN). In addition, a first MAC is generated using a first message and the first MAC is divided into a first MAC part and a second MAC part. A second MAC is generated using a second message and the second MAC is divided into a third MAC part and a fourth MAC part. A linear operation is performed between the second MAC part and the third MAC part to generate a first authentication MAC. The first message is transmitted with the first MAC part and the second message is transmitted with the first authentication MAC.

A method of transmitting K messages using divided message authentication codes (MACs) in a controller area network (CAN) includes: generating a MAC using a first message and a specific MAC, performing a first operation with respect to j using j-th messages subsequent to the first message and a second MAC part of the generated MAC, performing a second operation with respect to j using a result of the performed first operation and a j-th subblock subsequent to a first MAC subblock among K MAC subblocks obtained by dividing a first MAC part of the generated MAC, transmitting the first message along with the first MAC subblock, and transmitting K-1 j-th messages in an order of j, each of the j-th messages being transmitted along with a j-th result of the performed second operation.
